Aluminium foil
This product removes rust from metal no worse than any abrasive brush, only much more economically. In addition, every housewife has aluminum foil in her kitchen, but no brush.
Removing rust from metal at home is very simple and easy. In this case, there is no need to prepare any solutions.
Cut a small piece of foil, crumple it into a tight ball, and begin cleaning the surface.
The method removes corrosion on household appliances, for example, on an iron. It can also be used to clean corrosion from any metal surface in the house.
Cleaning with foil doesn't always help. When the pipe is completely rusty, don't waste your time, better buy a new pipe. Surely in a few months (at best) traces of corrosion will again appear on it.

How to clean a bicycle chain
Bicycle chain cleaning machine
Easy to use device. To clean a bicycle chain, you need to put a machine on it, fill it with the necessary cleaning fluids and turn the pedals. The machine may already come with cleaning liquids, but if they are not available, you can use, for example, Fairy or similar (but remember that the use of certain solvents during this procedure can cause corrosion of the plastic or even breakage of the cleaning machine).
This machine does not cope very well with cleaning bicycle sprockets. Therefore, if you want to thoroughly wash your bike chain, you should clean the sprockets later using a brush and rag.
The cost of such a machine varies depending on the quality, manufacturer and additional little things included, but on average it costs about 500-800 rubles. The machine performs its function well, but you will have to clean the sprockets with other means. The disadvantages are that it is not reliable and does not cope perfectly with cleaning the stars.
Chain brushes
Choose any brush that suits you and use it to get rid of dust and dirt. For better results, you can use some detergent. This brush will be convenient to take with you on a bike ride. The downside is that it is not the best cleaning result and is also highly labor intensive.
Cleaning in white spirit
This method is considered, if not the best, then one of the best for sure. To do this, you will need a plastic bottle or other similar container into which you will pour white spirit. Then, after removing the chain from the bike, soak it in the liquid for 15-20 minutes. To achieve the best effect, it is advisable to shake the bottle from time to time. Using this method, you can quite easily get rid of almost any contaminants.
Detergent, rag and toothbrush
The most budgetary method, but not particularly inferior to the previous ones. You will need to have a stiff toothbrush (the cheapest one will do) and some detergent (example: Fairy). Then soak a rag in the liquid and use it to wipe off all the dirt and old grease. What is difficult to wipe off, scrub with a toothbrush. You can also use a screwdriver in this method to get rid of old pieces of dirt. This is a budget method, albeit a very labor-intensive one.
Solvents and kerosene can be used as alternatives to household cleaners. There is some debate about the advisability of using gasoline as an analogue for detergent, but some cyclists use it too. When working with such products, we strongly recommend using gloves to avoid damage to the skin of your hands.
Combined chain cleaning method
The most labor-intensive, but at the same time the most effective method. Use all the tools and items listed in the points above. First, wipe the chain with a rag soaked in washing liquid, then use a cleaning machine, then start cleaning the dirt using special brushes and, if necessary, a toothbrush. The procedure ends with re-using the washing machine, and after all the manipulations the bicycle chain will look like new.
Chemistry
The best and fastest way to remove rust from metal is with a converter. Chemical reagents remove corrosion even in hard-to-reach places.
The converter will save you a lot of time. The main component in such compositions is phosphoric acid and other substances that accelerate the reaction of converting rust into iron oxide, which becomes part of the protective coating.
How to remove rust:
- First, the surface should be treated with a degreasing compound.
- Then apply rust converter. Wear gloves to avoid getting the product on your hands.
- Leave the composition on the metal for 15 minutes, this is enough for the rust to turn into orthophosphate. It turns gray.
- After which the converter must be washed off with plenty of water.
Rust removal is carried out very quickly. You can remove corrosion in one go, but sometimes you need to repeat the procedure.
Zinkar rust converter is used to work with metals such as steel. Not only can it wash away corrosion, this product creates a protective film on the surface so that it does not appear again.
Formalin
A composition that you can prepare yourself will help remove corrosion from a metal surface; the main ingredient is formaldehyde in a volume of 250 g.
Also, to prepare the solution you will need 250 ml of water, 50 g of caustic soda and 50 ml of ammonia.
The resulting mixture is diluted in 1 liter of water. Objects that require cleaning are placed in this solution.
But first, all products must be degreased. After treatment, wait half an hour, then rinse and dry the products.
Lemon juice
- Take the rusty item and clean it with detergent.
- Wait for the moisture to dry completely.
- Add six teaspoons of oxalic acid to a glass of water.
- Immerse the item in the solution for 30-40 minutes.
- Remove any remaining rust with a washcloth.
Advice! To clean small hardware, you can place it in a plastic container and fill it with converter. It won't be difficult to remove the marks. It is enough to leave it for a while, and then dry and clean it.

- Place small parts or paint the rusty surface with the solution using a brush.
- All that remains is to dry the elements and protect them from further oxidation.
Several types of rust can easily coexist on one piece of metal. In our country, iron is considered the most vulnerable to corrosion, and given the widespread use of alloys based on this chemical element, we can encounter rust everywhere.
Corrosion Prevention
To prevent your bike from rusting, you need to store it in a case.
The only way to protect your bike from rust is proper storage. For the winter, the vehicle is stored in a dry, warm room, in which humidity levels remain at the same level throughout the year. If the only place in the house suitable for wintering is the balcony, then the bicycle is put in a thick waterproof case.
In the spring, before use, the chain is lubricated with mineral oil. If chips appear on the frame, it is covered with paint and varnish.
If unpleasant orange and brown spots do appear, it is better to immediately use one of the described methods to eliminate corrosion. Otherwise, rust will spread and ruin the bike.
What can cause discoloration on jewelry?
Before choosing what you can use to clean your jewelry yourself, it makes sense to figure out where the darkening comes from. The fact is that the materials from which cheap jewelry is made are quite active. Therefore, they easily react with oxygen in the air, as well as with particles of sweat and fat that are released by human skin. The products of these reactions have a dark color, which can be observed with the naked eye on the surface of the jewelry.
Expert opinion
Irina Kovtun
Jewelry made from precious metals, such as white gold, is more inert and resistant to environmental factors. Therefore, they do not change their color over time.
Unusual ways
You can remove traces of corrosion using unusual but effective methods.
Coca Cola
You can quickly get rid of unpleasant traces of metal oxidation from a stroller, household utensils, and even a car body with the help of a popular drink - Coca-Cola. Soda should be poured into a plastic tray or container, and then items damaged by corrosion should be placed in it. Usually a few hours are enough for the drink to corrode even severe rust.
Soda can be used to remove rust from a circuit board or other delicate products. In this case, you need to soak a rag or sponge in Coca-Cola and wipe the surface. Repeat the action if necessary.
Advice! You can also use cheaper sparkling water. It is important that it contains phosphoric acid, because it is what transforms oxidation.
Ketchup or tomatoes
If there are expired canned tomatoes or ketchup in the refrigerator, do not rush to throw them away, as they can be used to clean metal from red marks. To eliminate them, just apply ketchup, tomato paste or tomatoes on them and leave for 20 minutes. If the damage is severe, the treatment time can be increased. Afterwards, you just need to wash everything well to remove traces of food.
Electrolysis
If a wash or folk remedy is not effective enough, electricity can be used to solve the problem. You need to follow the algorithm of actions:
- Pour warm water into a plastic tub or tray.
- Add a couple of tablespoons of salt or baking soda.
- Take a car battery charger.
- Screw a metal plate to one terminal.
- Connect the part from which you want to remove rust to another wire.
- Dip both ends into the prepared solution and apply current, setting the current to 4-6 amperes.
- Leave for 30 minutes or more.
- Remaining traces can be easily wiped off with a brush or rough sponge.
Use extreme caution when processing metal using this method. Do not remove the product from the bath until the power is turned off.
Choose the right option to remove rust from damaged metal and restore its aesthetics or functionality. To prevent the problem from returning, protect the surface with primer, paint, varnish, oil or another product.

2) Household chemical cleaning
- They try to remove rust mechanically using brushes or abrasive materials. The relatively low adhesion of oxides to steel makes it possible to quite effectively remove them from the surface of various products.
- Chemical reagents dissolve oxides. As a result of the interaction of Fe₂O₃ and FeO with acids, iron salts are formed. In this way it is easy to get rid of the oxide film.
- Heat treatment is used to heat the entire product. The coefficient of thermal expansion of the metal and oxides are different, so the surface layer of rust peels off. By cooling a metal product in a stream of liquid or air, the oxidizing coatings are destroyed. They fall down on their own.
Another common remedy that any housewife has in her kitchen. If necessary, you can buy lemon juice at your nearest grocery store. The advantage of treatment with citric acid is the formation of an oxide film. The layer will be able to protect the metal surface after removing the rust for a couple of days, which is enough to apply an anti-corrosion substance or lubricant.
Clean with baking soda
A food product such as soda is well capable of cleaning metal from rust. This tool is truly universal. Using soda, you can also wash clothes until they are white and remove coffee, blood and green grass stains.
- It is necessary to prepare the composition so that you get a texture like store-bought sour cream, but not too thick. To do this, you will need to mix baking soda with plain water in a separate container. Select the proportions yourself, focusing on the area to be processed.
- Apply the paste to the metal surface. Allow the product to sit for a while before rinsing with water. 30 minutes is enough, you can support it more, but it will not become more effective.
- After half an hour, scrub the surface with a brush with metal teeth, then rinse with water.
This technology is not particularly effective. Baking soda can only remove small stains at a time. If the processing area is large, more paste will be needed, and therefore more time and effort.
