How to clean a soldering iron tip with ammonia

How do I now clean the shower curtain from dirt with ammonia?

Over time, the shower curtain becomes dirty, stubborn stains and even mold appear on it. It is not always possible to wash it properly with a simple powder. I found a life hack online where the author, using a mixture of hydrogen peroxide and ammonia, quickly and easily cleaned a curtain of dirt. I tested this method and now I use it constantly.

Step 1. Prepare the mixture and soak

From a small container I mixed:

• 2 tbsp. l. ammonia;

• 4 tbsp. l. hydrogen peroxide;

I dipped a clean dish sponge into the resulting mixture and thoroughly treated the shower curtain along the bottom edge (this is the most contaminated place).

Left it for 30 minutes.

Step 2. Erase

Within half an hour the fabric became noticeably cleaner.

To finally get rid of dirt:

1. I loaded the curtain into the drum of the washing machine.
2. I added a little (literally 2 tbsp) regular powder.
3. I poured 2 tbsp into the drum. l. ammonia and peroxide.
4. I chose a short program with water heating at 30 degrees.
5. Activated the extra rinse.
6. I poured another 2 tbsp into the rinse aid compartment. l. ammonia diluted with water. When rinsing, ammonia strengthens the cleansing effect of washing and protects the curtain from dirt.

Step 3. Dry and evaluate the result

I stretched the damp curtain across the crossbar.

Soaking with ammonia and hydrogen peroxide really helped remove dirt and stains and left the fabric clean. The mixture helped lighten the damaged bottom of the curtain.

I did not notice any particular protective effect from using ammonia. A month later, the curtain still had to be washed as usual. True, soap scum and dirt came off easily, without additional soaking and reuse of the cleaning mixture.

Conclusion

The life hack works.

Shirt collar: how to remove yellow stripes, how to bleach them from greasy conditions

It is quite possible to wash a shirt collar at home, even if the dirt on it is very strong. Household substances and special chemicals help remove yellowness and gray tints.

Features of washing a shirt collar

When wearing a shirt, the collar is in especially close contact with the body. It is not surprising that yellowness from sweat and sebum quickly appears on it. Dirt is very noticeable, especially if the shirt is light-colored.

You can wash the gate if you follow some rules:

1. A stained collar must be washed immediately, without waiting for the dirt to be absorbed. Ideally, it is recommended to change white shirts daily; even after one day of wearing, the clothes lose their freshness.
2. Fresh dirt on the collar should not be rubbed with your hands or a napkin. This will only worsen the situation; sebum and sweat will penetrate deeper into the tissue structure, and it will be more difficult to remove them.
3. When cleaning a shirt, it is better not to use hard brushes; you should not rub the fabric too hard with your hands. Rough mechanical impact damages fabric fibers, making it more difficult to remove dirt from them. At the same time, the shirt can maintain a neat appearance for a long time, but it will be more difficult to return the whiteness of the collar each time.

The collar is the most vulnerable part of any shirt to stains.

Since it is quite difficult to wash the collar to its original color, it is recommended to carry out the treatment in 2 stages. First, the shirt is soaked in a basin and problem areas are locally treated with bleaching agents. Only after this is the entire product washed by hand or in a machine; with normal quick washing, dirt does not come off the collar well.

How to wash a shirt collar

Many chemicals and household products can be used to wash white collars. Among the most effective are:

• vinegar and hydrogen peroxide;
• laundry soap and starch;
• lemon juice;
• chlorine- and oxygen-containing industrial bleaches.

When choosing a detergent, it is necessary to take into account the characteristics of the material. If we are talking about a thick cotton product, you can wash the shirt with quite aggressive means and at high temperatures. But silk and synthetic items require delicate handling - you need to use liquid washing gels for them, and it is better not to use strong acids and alkalis.

How to clean a shirt collar using traditional methods

If chemical bleaches and stain removers are not at hand, you can wash the collar of a colored shirt or white shirt using simple folk methods. Homemade acids and alkaline preparations work well even on old stains.

How to wash a collar on a men's shirt with vinegar

Yellowness and gray-black stripes on the collar are easily removed by ordinary table vinegar 9%. Use it like this:

• moisten the soiled collar with water;
• a small amount of vinegar is applied to a cotton pad;
• gently wipe the dirty collar, trying to thoroughly remove the dirt;
• leave the shirt on for 15 minutes.

Vinegar removes both yellowness and fat from collars and cuffs well.

After the expiration date, the collar is rinsed several times in running water. Then the shirt can be washed in the usual way in a basin or in an automatic washing machine to remove any remaining dirt.

How to wash dirt off a shirt collar with ammonia and salt

Another effective household solvent is ammonia. To remove yellow and gray stains on the collar, you need to:

• dilute 1 small spoon of salt in 50 ml of ammonia;
• add 50 ml of clean water to the solution;
• mix the product and then apply it evenly to the soiled shirt collar;
• leave the clothes for 20-30 minutes so that the ammonia and salt have time to have the desired effect.

Dry ammonia for soldering

> Tools > Soldering flux

The article provides answers to the questions: what are soldering fluxes for and what do they consist of? Almost all metals are naturally covered with an oxide film. It is this circumstance that becomes an obstacle to liquid solder. To overcome this obstacle, fluxes are used.

What it is? This is a mixture of substances of organic and inorganic origin, which has the properties of removing oxides and reducing surface tension in solder areas. Such substances are called fluxes.

In addition, the product promotes better spreading of liquid solder and protects the parts to be connected during soldering from the influence of the external environment.

Types of fluxes for soldering

The main property of soldering fluxes is its chemical neutrality with respect to solder. The substance may be in the form of a liquid, solid or paste. The main types of fluxes for soldering are presented in the following list:

• rosin;
• ammonia;
• borax;
• orthophosphoric acid;
• acetylsalicylic acid;
• fppu 25.

Rosin

For quick and high-quality soldering, rosin is used as a flux. The basis of the substance is pine resin with the addition of turpentine. The technical characteristics of rosin are determined by GOST 19113-84.

The properties of pine resin as an auxiliary material for soldering have been known for a long time. Rosin, not having a crystalline structure, is an amorphous glassy fragile body. The translucent mass can be of different shades: from pale yellow to dark brown.

Rosin is hydrophobic, but easily dissolves in alcohol and acetone. Flux is widely used at home for soldering radio components, copper wiring and other things. The material has a low melting point. When heated above 700 C, the flux becomes liquid and is easily transferred by the soldering iron tip to the soldering site.

Soldering wires with rosin

If you need to solder two ends of the wires, proceed as follows:

• The ends of the wires are stripped of insulation. They do it with a knife;
• If the wire is stranded, then it is twisted into a pigtail by hand;
• The exposed wires are heated with a soldering iron;
• The soldering iron tip is dipped into rosin in order to then transfer the product to the metal;
• Using longitudinal movements of the tip, the pigtails of the wires are impregnated with flux;
• Then they put molten solder on the soldering iron tip;
• By running a soldering iron along the ends of the wires, the metal is tinned;
• Tinned braids are twisted together;
• A thin layer of molten tin is applied to the junction of the wires with a soldering iron tip.

Ammonia

The chemical compound ammonium chloride NH4Cl is known as ammonia. Ammonium salt looks like a white, odorless powder. Liquid flux is a solution of 77 parts salt in 100 parts water.

Ammonia is obtained as a by-product of soda production. At soldering temperatures (above 3380), ammonium chloride vapor completely decomposes into two compounds: NH3 and HCL.

Why are ammonia fluxes needed? They are used for tinning and soldering steel products. Ammonia, in contact with heated metal, decomposes into two substances: ammonia (NH3) and hydrochloric acid (HCL). The acid dissolves the metal oxide layer and cleans the soldering surface, ensuring 100% adhesion of the solder to the metal.

Plastic packaging with ammonia

On sale you can always find a solution or powder of ammonia intended for soldering. The flux is sold in convenient plastic packaging. The product is also used to clean soldering iron tips from carbon deposits and scale.

Borax

This substance is extracted from drying salt lakes. In addition, borax solder paste is obtained by neutralizing boric acid with sodium carbonate. The resulting mixture is dehydrated by evaporation followed by filtration of the solution.

To make soldering flux with your own hands, proceed as follows:

• boil the soda solution in a container, stirring it constantly;
• Having brought the solution to a boil, pour in boric acid granules, preventing the mixture from foaming;
• the solution is boiled for 30 minutes;
• then the mixture is cooled and filtered.

The result is a white crystalline powder. The resulting borax is a high-temperature flux that is used for soldering joints of cast iron, steel, and copper alloys. Prepare a borax paste by grinding the powder in a mortar and adding boric acid in a 1:1 ratio. To increase the chemical activity of the flux, chloride and fluoride salts are added to it. During soldering, a layer of salt will form that will need to be removed.

An example of soldering copper parts using borax

There are cases of failure of a water heating column or installation of a heated floor system and other water heating equipment. You need to connect the pipe to the fitting. In order to solder such a connection, proceed as follows:

1. The end of the pipe and the inner surface of the fitting are cleaned with fine sandpaper;
2. Borax in the form of solder paste is applied with a brush to the joints;
3. The pipe is inserted into the fitting and turned slightly in both directions. This gives an even distribution of flux over the entire joint surface;
4. Use a gas burner to heat the assembly from the outside so that the heat penetrates inside;
5. A rod of soft solder is led along the seam, following the burner flame;
6. Under capillary action, the solder will begin to penetrate deep into the neck of the fitting;
7. Solder must be inserted from bottom to top in both directions;
8. Soldering must not be cooled with water. The connection should cool naturally;
9. Remains of flux are removed with a damp cloth.

Orthophosphoric acid

The formula of this inorganic substance looks like H3PO4. Acid is an effective rust remover. Along with this, phosphoric acid is used as a soldering flux.

The acid is used for soldering low-alloy and carbon steels. The flux effectively removes the oxide film on both the base material and the solder. Rust, under the influence of acid, becomes loose and floats on the surface of the flux. A protective layer is formed at the cleaning site, which prevents the formation of a new oxide film. After soldering, all acid residues are easily washed off with warm water.

This flux is successfully used when soldering parts made of stainless steel, nickel and their alloys. Ferrous metal compounds are also treated with acid. In radio engineering, acid is not used because it can corrode contacts.

Acetylsalicylic acid

A situation may arise that you urgently need to solder the wire connections, restore contact in the electrical circuit, but there is no flux for soldering in the house. Don't despair. A regular aspirin tablet (acetylsalicylic acid) will help out.

This is the case when you can make a soldering flux with your own hands. The wire processing process is as follows. The exposed section of the wire is pressed with a tinned soldering iron tip to an aspirin tablet. As a result of the movement of the soldering iron tip along the wire, the varnish on the metal is destroyed, and the conductor is covered with a thin layer of solder.

  Why do you need soldering acid when soldering?

FPPU 25

There is a legend among people about a universal soldering agent that was used in military factories of the Soviet Union. What is FPPU 25 flux? This is a solder paste similar in composition to epoxy resin. The name of the product is the initial letters of the words: flux, universal soldering paste.

You can still find solid sealed pipes with this flux made in the Soviet Union. The paste is truly universal and suitable for soldering many metals. Its only and significant drawback is the toxic fumes that arise during soldering work. Working with such flux at home is extremely hazardous to health. Today on the market you can still find a soldering agent under this name.

How to solder correctly

How to tin a soldering iron: preparation and care of the soldering iron

This chapter will talk about how to properly solder simple connections of metal parts. In order to obtain high-quality soldering, you need to follow certain rules. A summary of these rules is reflected in the following paragraphs:

1. A soldering iron, a small sponge or rag, solder, tweezers and wire cutters are laid out on the table;
2. The soldering iron is connected to the mains, trying to melt the solder;
3. The end of the tip is covered with molten solder;
4. The ends of the wires are removed from the insulation using wire cutters;
5. Using short movements with a sponge, remove the remains of old tin from the surface of the heated tip;
6. The areas to be soldered are tinned with solder using a soldering iron, alternately dipping the tip into a mass of flux (rosin or other flux);
7. Clamping the ends of the wire together with tweezers, apply solder to the tinned areas. If the wires are of small diameter, then their ends are simply twisted and then soldered;
8. After the soldering area has cooled, check the connection for strength;
9. Remove flux residues with a cotton swab dipped in alcohol or acetone.

There is no need to master the technique of soldering printed circuit boards on your own. It is best to gain experience in this matter in direct contact with the master. It is the specialist who will teach you in a short time the soldering technique, the correct choice of soldering equipment and the selection of the required flux.

How not to spoil silver by trying to clean it with ammonia?

Cleaning silver with ammonia has its pros and cons. On the one hand, the caustic substance allows you to quickly clean products. With it you can easily remove dark spots and dirt in hard-to-reach places. Ammonia will dissolve everything without tedious friction. But there are also disadvantages.

It can ruin low-quality products - cause cloudiness and porosity. It cannot be used to clean blackened silver, items with pearls and some other inserts.

You also need to handle it carefully so as not to get a chemical burn to the skin and mucous membranes of the nose and eyes.

Can silver be cleaned with ammonia?

In the age of technology, using ammonia to clean silver is at least illogical. There are a lot of special tools: HG, Re:Shine, Aladdin and others. They do their job perfectly and are quite inexpensive, considering the volume of the bottle (from 250 rubles for 300 ml).

But if you really want to, you can use ammonia. It is also popularly called ammonia and ammonia. Although it's not exactly the same thing. Ammonia is a gas, and ammonia is an aqueous solution of ammonium hydroxide, or 10% ammonia in water. At this concentration, the ammonia solution is not dangerous for silver. Except for 3 types of products.

Exceptions

Some types of silver items require special care and careful cleaning. Ammonia can damage them.

You cannot clean with a folk remedy:

• blackened silver;
• low-quality silver with a high copper content, products with silver plating;
• jewelry with pearls, amber, coral, ivory.

The remaining stones are not afraid of short-term exposure to ammonia. You can use it to clean products with cubic zirconia, sapphire, emerald, ruby, garnet, topaz and turquoise without fear.

How to clean products correctly?

Blackness on silver is a product of oxidation. Ammonia reacts with oxides and turns them into ammonium salts. It does not dissolve silver, but impurities, which are almost always added to the alloy, can. Ultimately, you may end up with a “dead” piece of jewelry—dull, rough, and discolored. To prevent this from happening, you need to follow 3 rules:

1. Note the time. You can't keep silver in ammonia for long. Use a watch.
2. Maintain proportions. Do not pour liquid onto your eye. Often, ammonia is diluted with water. Do not increase the dosage and strictly adhere to the recipe.
3. Clean gold and silver jewelry separately. If you put them in ammonia together, a chemical reaction may occur that will cause the silver to yellow.

Safety precautions

When working with ammonia, you need to take precautions. A pungent odor is only half the story. Inhaling vapors can cause poisoning. And if handled carelessly, ammonia can cause burns to mucous membranes and irritation to the skin.

7 golden safety rules when working with ammonia:

1. Don't try to remove the lid with your mouth!
2. Do not lean over ammonia to avoid inhaling fumes.
3. Pour the liquid carefully to avoid splashing.
4. Use tweezers when removing the product from the ammonia.
5. Wear rubber gloves to protect your hands.
6. Open all windows while cleaning. The room should be well ventilated.
7. If ammonia gets on your mucous membranes, immediately rinse the area with water and consult a doctor.

Step-by-step instruction

To clean silver at home, you will need the following materials:

• ammonia 10% (ammonia for external use and inhalation);
• water;
• utensils not used for drinking and cooking;
• soft cloth (flannel, suede, wool).

Step-by-step instruction:

1. Prepare a solution of 1 part ammonia and 10 parts water.
2. Place the items in it.
3. Waiting time is from 15 to 30 minutes.
4. Rub the stained areas with a cloth.
5. Rinse under running water and dry.

Soak the silver in ammonia for a short time. It is better to repeat the procedure than to spoil the product.

Folk recipes

Previously, when special compositions for cleaning jewelry were in short supply, people actively used improvised means. Recipes with ammonia were considered the most effective. The pharmaceutical product was used in its pure form and mixed with other solvents for better effect.

With hydrogen peroxide

Peroxide affects the oxidative process with the help of oxygen. Together with ammonia, it actively dissolves plaque on precious jewelry.

Recipe:

1. Pour a glass of water into a bowl, add 2 tbsp. spoons of ammonia and hydrogen peroxide, mix.
2. Dip the jewelry into the solution and wait 15 minutes.
3. After the specified time, arm yourself with a soft cloth, preferably lint-free, and rub the products.
4. Rinse with water.

With "Fairy"

Dishwashing detergent acts on the greasy traces left on the product after contact with human skin. Together with ammonia, Fairy and its analogues effectively remove plaque and rid silver of blackness.

Recipe:

1. Add 1 teaspoon of Fairy and 2 tbsp to a glass of water. spoons of ammonia.
2. Immerse the products in the solution for 20 minutes.
3. Remove and rub with a piece of cloth.
4. Rinse with water.

With tooth powder

This recipe is suitable for cleaning products with old plaque, but without stones. Tooth powder, like ammonia, can be found at the pharmacy. It acts as an abrasive, removes plaque and polishes the surface.

How to clean silver from plaque at home:

1. Mix 5 tbsp in a glass. spoons of water, 1 tbsp. spoon of tooth powder, 2 tbsp. spoons of ammonia.
2. Dip a cloth into the solution and clean the items.
3. Rinse off any remaining composition with water.

Prevention of darkening

Silver plaques 6 times faster than gold. If gold items need to be cleaned once a year, then silver items need to be cleaned on average every 2 months.

The cause of blackness is impurities. Copper is added to silver for strength. The lower the sample, the more impurities there are in the product and the faster it becomes contaminated. Copper reacts with sulfur from human sweat, and black crystals appear on the surface of the jewelry - silver sulfide. Sulfur may also be present in the air.

To keep your silver items shiny and clean longer, take the following steps:

1. Choose a dry and dark place for storage.
2. Wrap the items in a soft cloth so that they do not touch each other.
3. Remove jewelry when bathing, cleaning, or applying cosmetics.
4. Don't leave silver wet. Wipe up spills immediately.

It is believed that silver jewelry darkens faster on people who have problems with stomach acidity.

Silver is a noble metal. He is credited with healing and mystical properties. Many people love silver jewelry much more than gold. But in order for them to serve for a long time, it is necessary to follow the rules of care. Ammonia is an effective home remedy for black on silver. However, its use is associated with a certain risk. Therefore, when choosing ammonia for cleaning, you need to study the list of “contraindications” and strictly follow the instructions.

Unusual use of ammonia in the country and at home

Not many people know that the pharmaceutical product - ammonia - can be used in everyday life. We will tell you about five options for using a penny product in the country and at home.

Gardeners can stock up on this product, since flower and vegetable crops love ammonia subcortex. It’s easy to do: take 50 ml of ammonia for 4 liters of water and mix everything. This composition is used to water seedlings of tomatoes, cucumbers, bushes of lilies, geraniums, clematis and other plants.

After such watering, garden plants will delight their owners with a healthy, strong appearance. By the way, indoor “inhabitants” will also not mind such feeding. Ammonia fertilizer, in addition to benefiting flowers, will also rid people of mosquitoes and midges in the room.

Window cleaning

Washing windows is a thankless job. Once you put them in proper shape, rain or wet snow will again leave streaks on the glass.

For perfect cleanliness and to make it easier to wash off the settled dirt later, a special composition is used. It is recommended to wipe already clean glass with a mixture of water, glycerin and a small amount of ammonia.

The proportions of water and glycerin in milliliters are 30:70. Just a few drops of ammonia are added to this composition. Ice does not form on glasses wiped with this solution; the glycerin film prevents this. It also helps to quickly remove settled dirt.

Bleach

Ammonia will also help in washing and bleaching clothes. It will soften the water and neutralize magnesium salts, which cause the formation of yellowness on white things. To prevent this from happening, soak linen and cotton products in soapy water, into which 5-6 tablespoons of ammonia are poured. To enhance the whitening effect, add a few tablespoons of turpentine composition.

But woolen and silk items are bleached in a different solution. To prepare it, take 12 liters of water, 8 heaped tablespoons of rock salt, 60 g of washing powder, 3 tablespoons of peroxide and 30 milliliters of ammonia. Linen made of wool and silk is kept in this solution for up to 4 hours.

Shine furniture and household appliances

Ammonia will remove stains and grime from upholstered furniture. To do this, add 50 ml of ammonia and table vinegar to 1 liter of water. Mix the mixture well and clean the contaminated upholstery with it.

Remove dirt with a cloth or soft sponge, then wipe the surface with a dampened cloth, rinsing off any remaining composition. This solution is also suitable for wiping household appliances.

Against ants in the kitchen

The pungent smell of ammonia will repel insects for a long time. Therefore, it will be easy to fight hordes of ants in the kitchen that appear from nowhere. It is enough to make a solution of 1 liter of water and 100 ml of ammonia.

The resulting composition should be used to wipe all the furniture in the room where the “tenants” tend to nest. The specific smell will disappear in a matter of minutes. It is absolutely safe for people, but insects will forget the way to this place. They will feel this “aroma” for a long time and will not want to appear here anymore.

Ammonia will also save you in nature from annoying midges and mosquitoes. To find peace from insects, you need to spray this remedy around the tourist shelter. The same composition helps relieve itching and eliminate the feeling of discomfort from an insect bite.
