Proven ways to remove oxide from aluminum products at home

Aluminum products are used very widely.
They are light and comfortable and have shine. But during operation, the shine fades quite quickly, and oxide forms on the surface, which greatly spoils the appearance. To solve the problem with the oxide that appears, you can use special means and folk recipes, as well as adhere to the operating rules.

We will tell you how to remove oxide from aluminum in this article.

How to clean with improvised means?

When using aluminum items, dark spots appear on their surface. Oxide can be removed using simple cleaning methods.

Lemon acid

To treat an aluminum container, it is necessary to prepare a solution in the following proportion: for each liter of water - 2 tablespoons of citric acid. The resulting solution must be boiled for a quarter of an hour (or a little longer if there is a lot of oxide). After this, the container is washed.

Apples

Fruit acid, which is found in fresh apples, copes well with oxide.

Procedure:

1. The fruit is cut in half.
2. Dark spots are rubbed with a cut.
3. Leave to act for 30 minutes.
4. The container is washed.

Coca Cola

The sweet carbonated drink contains orthophosphoric acid, which copes well with the oxide. The use of Cola is very simple:

• pour the drink into an aluminum container;
• leave for 1.5 hours;
• Rinse.

Sorrel

Fresh sorrel is required for processing. Application procedure:

1. A bunch of leaves is placed in a container that needs to be processed.
2. Fill the container with water.
3. Boil over low heat for half an hour.
4. The solution with the leaves is poured out.
5. The container is washed.

Salt, vinegar and mustard powder

If the darkening from the oxide is on the outside of the container, you can use the following method:

• add 1 tablespoon of salt and mustard powder into a bowl;
• pour in 1 tbsp. vinegar;
• stir;
• using a sponge, apply the resulting slurry to areas with oxide;
• leave for a quarter of an hour;
• rinse with warm water.

Kitchen salt

Table salt diluted with water can also be used to eliminate the oxide. Work order:

1. Pour 2 tbsp into a bowl. salt.
2. Pour in 1 tsp. warm temperature water.
3. Mix.
4. Apply with a sponge to areas with darkening.
5. Leave for 30 minutes.
6. Rinse.

Soda solution

To eliminate oxidation from the surface of aluminum objects, you can use an aqueous solution of soda. This recipe is suitable not only for dishes, but also for removing darkening from various parts of mechanisms.

Pour water into a large container in which aluminum objects will be cleaned by immersion and add baking soda in the following ratio: for every liter of liquid - 2 tablespoons of powder.

Processing order:

• pour the soda solution into the container;
• the item to be processed is lowered into the container;
• bring to a boil;
• boil for at least 10 minutes, monitoring the effect.

It may not be possible to completely eliminate foci of oxidation the first time, so if necessary, the process can be repeated even several times.

Corrosion is classified according to the degree of damage to steel as follows:

• Corrosion stains: characterized by shallow penetration depth. Such corrosion spreads broadly, not deep into the iron.
• Pitting is small spots that penetrate deep into the body of a material. With further development of pitting corrosion, through holes appear on the steel.
• Through corrosion is through damage to the material.
• Under-film corrosion: pockets of rust form under the surface of the coating. Layers of paint in places where rust has formed swell. But sometimes subfilm corrosion remains unnoticed until the steel undergoes complete destruction.

Material processing

Treating the material against rust before painting can be done using the following methods:

• mechanical;
• chemical;
• thermal.

Use of household chemicals

You can find special products for cleaning and polishing aluminum products. Their use gives a good effect, but not all of them can be used to clean dishes from the inside in contact with food.

Shine Coins for cleaning and polishing

The domestically produced product is intended for cleaning and polishing products, both aluminum and coins . The product contains surfactants and an ultra-nanodisperse abrasive component, which is gentle on the aluminum surface.

Shake the product before use. It is convenient to apply the drug with a sponge using rubbing movements. After processing, the aluminum product is rinsed. The cost for a volume of 150 ml is from 250 rubles.

Autosol Aluminum Cleaner

Aluminum cleaner is an auto chemical product. The product is produced in Germany. The drug is suitable for eliminating complex contaminants and areas of oxidation . Can be used to process aluminum cookware.

The cleaner is applied by spraying and works within 10 minutes. After the treatment, the surface is cleaned and polished with a rag. Cost for 500 ml – from 600 rubles.

Cleaner Moreman

In addition to oxide, the product removes lime deposits, rust, etc. The cleaner is biodegradable. Manufacturer – Spain. Price for 1 liter – from 1,500 rubles.

What to choose in the store

When you go shopping for a stainless steel dish cleaner, you need to:

• analyze reviews - recommendations will help you make the right choice;
• study the composition - the product should not contain abrasives, chlorine and ammonia;
• pay attention to the markings - the manufacturer must indicate for which materials a particular product is suitable.

It is advisable to give preference to proven means. Judging by the reviews, they have proven themselves well:

• "Dafor";
• "The Shine of Steel";
• "Selena";
• "Shumanite";
• Luxus;
• Help;
• Delu;
• Dr. Beckmann;
• Fresh.

Some housewives use oven cleaners to clean stainless steel cookware from grease and other contaminants. They apply the gel for 15-20 minutes, then wash the product with regular detergent.

Removal from aluminum cookware

Cookware made from aluminum is susceptible to scale formation. This circumstance is directly related to the composition of tap water. The more metal salts it contains, the more actively scale will form. For processing, you can use the tools that you have on hand.

Lemon acid

For descaling treatment, a solution of citric acid is prepared . For every 1.5 liters you need to add 25 grams of acid. The container is brought to a boil and left to cool. After this, you can rinse the inside.

Vinegar

For processing you will need table vinegar. It is diluted half and half with water or used undiluted. The solution is poured into the container so as to cover the areas with scale.

After bringing to a boil, remove the aluminum pan from the heat and allow to cool. The liquid is drained, and the dishes themselves are washed and boiled with clean water.

If the smell of vinegar remains on the dishes, you can eliminate it in a simple way: put an orange peel in a container and fill it with water. After a quarter of an hour, the container can be washed and used for its intended purpose.

Overview of types of burrs and defects

A burr may look like a sharp edge of a metal sheet that has been pulled up. It occurs during any metal forming process - cutting, welding, coordinate punching of products. They are divided into two types based on their appearance:

Mechanical: These are again divided into two types: those resulting from overturning and those resulting from breaking. The first and last types occur during drilling, trimming, guillotine cutting and cutting. They can be eliminated by using the right tool and setting the correct speed and feed rate.

Thermal: Occurs during the thermal processing process and is caused by heat from plasma or laser cutting. They are easily avoided by properly setting the correct cutting speed on these rigs and using the proper optics and cutting attachments.

During the waterjet cutting process, corrosion may occur which can be removed using brush modules, sandpaper and other similar tools.

Where does rust come from?

To know how to deal with rust, you need to know where this “enemy” comes from. Rust can appear on any metal surface, and you should not “underestimate” it: this problem can lead to the fact that metal objects affected by it will have to be completely disposed of.

Rust can only appear with the participation of water or moist air. Under such conditions, iron molecules react with oxygen molecules, in other words, iron is oxidized. To avoid this, the surface is treated with an anti-corrosion coating. If this has not been done, the rust can be removed - there are a large number of different ways to do this.

All of the methods listed below will help get rid of rust of any nature on absolutely any object, be it some kind of metal part, car body, spare part, mesh, pipe, knife or anything else.

The methods below will help you get rid of rust on any item.

How to remove rust from a metal surface using heat treatment

During heat treatment, damage is affected by high temperatures, often combined with air or water flow.

This type of work to remove rust from metal at home is carried out with a hair dryer.

The hot air flow will remove rust stains by progressively softening the scale and breaking it up.

Garlic

Garlic not only wards off vampires, but also restores the sunny shine to your jewelry. Especially if it is made of copper:

1. Take a couple of garlic cloves and finely grate them.
2. Add salt to the grated garlic (no more than a pinch).
3. Apply to darkened jewelry.
4. After 8-10 minutes, wash off the garlic.
5. Wash the chains and ring thoroughly (with soap) to remove the not very pleasant garlic smell.
6. Wipe the stones with a dry cloth.

Soap solution

To clean your jewelry, a regular soap solution will be enough. This product is especially good for the same “silver”, for jewelry with pseudo-gold plating, as well as “glass” (rhinestones):

1. You take soap (the more caustic it is, the better), dissolve it in water. Try to make the solution as concentrated as possible.
2. Add a thickener (glycerin is fine).
3. You dip your pets into a caustic foam “bath.” Keep it in it for 10-15 minutes.
4. You shake the “bathtub” a little so that all the rust and dirt comes off more easily.
5. Pull it out and wipe it with a sponge (soft).
6. Finally you rinse with water.

If the shine on your jewelry has not completely returned and it is still dull, you will have to clean it again:

1. Add a tablespoon of ammonia to the foam bath.
2. You take a toothbrush and soak it in the soapy solution.
3. Rub it well on chains and stones.
4. You wash off the remaining foam from them.

Well, now everything is in order - the trinkets are prettier again.

Baking soda

The best way to “rejuvenate” jewelry that imitates silver jewelry is with a baking soda mixture. Do the cleaning product like this:

1. Take a little soda and add water.
2. Stir a little to form a mixture similar to puree or thick porridge.
3. Apply a mixture of water and soda to the “almost” darkened jewelry.
4. Let the baking soda decorate them for about 20 minutes.
5. Then rinse the mixture with water or brush with a toothbrush.
6. Wipe the jewelry with a dry cloth.

Well, these cute metal trinkets have regained all their beauty. It's time to take them for a walk.
