What should I do if the shell of an electrical appliance that has been used for a few years turns ye

In life, I believe that friends like to buy some white things, such as white furniture, white appliances. This is because white makes people look clean and fresh. The main cause of yellowing of household appliances is the aging of the white plastic casing, as well as the change of ultraviolet or other light rays in the plastic chain polymer and other polymer materials.

Because our home appliances are basically made of some plastic polymer composites. Another point is that the casing of household appliances will slowly turn yellow due to corrosive substances.

Let the appliance return to white, but remember not to use too much force, just wipe it gently. In home life, there is often no problem with the quality of electrical appliances that have been used for several years, but the shell is yellow, which directly affects the appearance level of electrical appliances and directly brings a "minus" effect to the living space, so people hope to find a way to solve their problems and restore the electrical shell to as new as new.

These shells are basically polymers, and "toners" or "masterbatches" can be added to obtain various colors during injection molding, so that the shells have different colors for users to choose. In the "toner", it is divided into "high temperature toner" and "ordinary toner", because enterprises often use "ordinary toner" in consideration of the cost, but "ordinary toner" will decompose and change color at high temperature, so the shell appears yellowing.

Toothpaste is an excellent multi-purpose cleaner for removing dirt from the surface of the enclosure. It is recommended to use a white toothpaste to remove contamination and remove the yellow color. The toothbrush has slight friction and will not damage the surface of the appliance case, and the white and yellow appliance case can turn white.

If the electrical shell has been yellowing at home for a long time, such as the yellowing shell of the wall-mounted space, at this time you can use plastic yellowing agent to solve the problem of yellowing the shell. By using this special yellowing agent, the shell can be whitened and 70 to 80 percent brand new so that the overall appearance will not be affected.

If the shell of an electrical appliance at home has been yellowing for a long time, such as the yellowing of the shell of a wall-mounted space, you can use a plastic yellowing agent to solve the problem of yellowing of the shell. Through the use of this special electrical shell yellowing agent, the shell can be turned white, so that it will not affect the overall aesthetics. Hydrogen peroxide can be used directly to clean the white shell of the electrical appliance, and through the chemical action of hydrogen peroxide, the original yellowed shell can be bleached and restored to a new appearance.

Baking soda and toothpaste can be said to be a "one-size-fits-all" combination in life, which can help solve many problems in life, including removing the yellowing of electrical housings.

It may be that it has been exposed to direct sunlight and irradiation, it may be that it has been used for a long time, and it may be that the temperature in this appliance is relatively high; You can brush it with toothpaste or toothbrush, soak it in orange peel or rice water for a period of time and wipe it clean, or you can use vinegar to remove the mold on it.

Because the enclosures of electrical appliances are plastic, they may oxidize when placed in a damp place, which will corrode, resulting in yellowing of the enclosure; You can use a rag dipped in laundry detergent to wipe it, and if the yellowing is more serious, you can ask a professional cleaning staff to clean it.

First of all: we need to understand why the shell of the appliance turns yellow.

Because most of the shells of household appliances are plastic products, plastic is a polymer material, which is affected by oxidation, ultraviolet rays, temperature and other reasons in the process of long-term use. The properties of the polymer will change, coupled with the so-called aging, so yellowing is inevitable.

Are there any tips to solve this problem?

1: If you want to completely solve the yellowing surface of the plastic shell and restore the electrical shell to new state, you can either use a grinding machine to re-polish the plastic shell and polish the surface layer that has aged and yellowed. Leak out the bottom layer that has not aged and turned yellow.

However, this requires certain technical means, if you simply use hard objects to scrape, it is easy to scratch the plastic surface, which is not only ugly, but also uneven.

2: Now there are some so-called "little tricks" to use toothpaste, wind oil essence, vinegar, baking soda, facial cleanser and so on. If it is for household appliances that have been used for many years and the shell is obviously aging and yellowing, it can be said that these methods are basically useless operations (I don't believe you can give it a try, after using the old household appliances that have been yellowed for ten or eight years, no matter how much you touch the toothpaste), it is useless).

3: Judge the degree of aging according to the depth of color and the time of use of the appliance. For example, some home air conditioners and washing machines have only been used for 1 or 2 years after they were bought, and they look a little yellow.

But this is not because the wind oil essence and toothpaste play a special role, but because the toothpaste plays the role of putty, and the oil in the wind oil essence plays a bright role. It is difficult to reverse the aging of the plastic composition and make the plastic shell white.

Tips: 1: The fastest aging appliance in the home is the washing machine on the balcony. Because of prolonged exposure to the sun. Accelerates the aging rate of plastics. Therefore, we can usually add an outer cover to the washing machine, which can slow down the aging and yellowing of the shell.

2: The current production process is much better than before, and under normal circumstances, it is almost time to replace the yellowing. Although the appliance is not broken, it is also necessary to pay attention to the service life, because after a long time, the main components and wires inside the appliance will age, reduce performance, and consume electricity.

3: There will be some chemicals for cleaning the yellowing of household appliances on the Internet, and the use steps of some products are quite complicated. One will need to be wrapped, and the other will need to be sunbathed.

Let's not talk about the effect? The point is that it is also very inconvenient to move around. Like some home appliances, if you move around, you still need to install it twice.

White household appliances, after a long time, basically have the phenomenon of yellowing. The main reason for this is that white plastic or topcoat, after long-term exposure to the air, will change color after oxidation, and the color will become darker, close to yellow.

This oxidation is irreversible and is not a surface dirt, so it is difficult to remove unless the surface layer is yellowed by grinding off.

The shell of the electrical appliance is yellow, one is to update it, buy a new one to replace it, and the second one can also use wind oil essence or toilet water, and gently wipe it with a soft cloth, so as to alleviate the yellowing phenomenon.

It can be cleaned with a stain remover, and it must be washed frequently to keep it fresh and leave no traces of oil.

How to restore the original luster of the electrical shell that has been used for several years is yellow?

The shell of household appliances is made of polymer material composite materials, and the most feared of plastic is the ultraviolet radiation in the sun, and the hazards of its continuous high temperature and organic chemical cleaning liquids, which will become more and more yellow over time, so many household appliances bought have been yellowed for two years. According to the application of the electric grinding machine, the plastic shell is polished again, and the material that has long been aged and yellowed is polished out. Leak out the bottom layer that has not yet aged and turned yellow.

Bleach with hydrogen peroxide cleans. This kind of bleach is generally sold on the market, and for small plastic parts, you can put the yellowed plastic parts into a multi-vessel filled with bleach, soak them for more than a week, and then dry them to restore their original appearance.

Spray the surface of household appliances with antiyellowing agent and then clean them as they go. Because the yellowing agent itself changes with the material of the home motor shell, it can wipe off a layer of yellowed material of the case.

Method 2: Apply hydrogen peroxide to complete the solution. In the case of hydrogen peroxide, water should be released in the double water, and then the blending should be carried out. Later, a towel should be dipped in the prepared hydrogen peroxide solution to scrub, so that the mild yellowing can be reduced.

Method 3: Cleaning with detergent. After adding water to the cleaning solution, we then use a damp rag to clean the surface of this electrical product. In this way, you can add some of the appearance of electrical products, and all the dirt that is attached to it is cleaned and tidy, so that the household appliances will look new.

Method 4: You can also use a special type of disinfectant alcohol to carry out cleaning. Disinfectant alcohol is configured according to the concentration value, and in our case, the surface of the electrical product is sprayed with disinfectant alcohol and then cleaned with a towel.

That way, you can also wipe off a lot of electrical products. However, it is necessary to pay attention to the use of disinfectant alcohol, sometimes it is not possible to see the use of fire, and it is very easy to cause fire.

You can use some cleaning agent to wipe it, you can also use some disinfectant to wipe it, you can also use some stain remover for cleaning, you can also use some iron sand for sanding, you can tear off the protective film on the surface.

It can be cleaned with bleaching with hydrogen peroxide, baking soda with toothpaste, or with white vinegar.

I think you can use some yellowing agent to clean it, so that you can remove the yellow stains from the outside of these appliances, and you can also use soda with toothpaste, and you can also use white vinegar with lemonade.

We can pour baking soda with white vinegar, stir well, and wipe the shell of the appliance to restore its original luster.

Tip 1: Use a yellowing agent for processing.

1. We first scrub the surface of household appliances with a clean rag. 2. Spray the surface of the electrical appliance with antiyellowing agent, and then scrub it accordingly. Due to the change between the yellowing agent itself and the material of the electrical shell, a layer of yellowed material of the shell can be wiped off.

Tip 2: Use hydrogen oxygen for processing.

When we use double water, we add water to the double water and then make it. After that, use a cloth dipped in the prepared hydrogen peroxide to wipe it, so that the slight yellowing can also be relieved.

Tip 3: Scrub with detergent.

We mix the detergent with water and then use a damp rag to scrub the surface of these household appliances. In this way, you can add some of the surface of household appliances, and all the stolen goods that are attached to them can be scrubbed clean, so that the appliances will look new.

Tip 4: You can also use special disinfectant alcohol to scrub.

Disinfectant alcohol is prepared according to the concentration, and when we use it, we spray disinfectant alcohol on the surface of household appliances and then scrub it with a rag. This can also wipe off a lot of household appliances. However, it is necessary to pay attention to the disinfection of alcohol, sometimes you cannot see the open flame, which is easy to cause fire.

The yellowing of household appliances for a long time is due to the problem of heat, that is, the heat of the electricity itself cannot be dissipated, and there is no good way to turn yellow from the inside out.

Because the electrical shell is exposed to the air for a long time, the white factor on the surface is oxidized, so it appears yellow, which is generally unavoidable, because air is everywhere.

If the household appliances in the house are yellow, first of all, we can use some baking soda to clean it, which is also okay.

Turn off the electricity and brush it with dish soap or steel wool, and take advantage of the fact that the only way is to clean.

Let's talk about why the casings of these household appliances are prone to yellowing. In fact, it is very simple, because the shells of these household appliances are made of plastic, and they are most afraid of ultraviolet radiation, coupled with the influence of temperature, as well as the dish soap and disinfectant commonly used in brushing household appliances, which will cause chemical reactions and make the plastic gradually turn yellow. For example, household appliances such as air conditioners, water dispensers, and washing machines will look particularly old once the shell turns yellow.

It looks like it's been over 20 years old, but when I look at my shopping history, it's less than 5 years old.

<> a good new house, just because these things become old houses, you say let life not be angry. When I yellowed the washing machine, I bought "plastic yellowing agent" on the Internet, and the owner gave me a tutorial and would do it step by step. I didn't have much hope at first, but it turned out really good.

Although it's not brand new, it does look a lot better than before. The cleaning power of toothpaste is incredible, and a lot of dirt can basically be removed with a toothbrush.

Using a toothbrush, squeezing toothpaste, and gently wiping the surface of the appliance can remove yellow stains without scratching the surface. Many friends know that washing rice water has a certain cleaning effect, and orange peel is a bit strange, in fact, both have a good cleaning ability. In addition to the yellowing of the white casing of some appliances, the white tape in the refrigerator now sometimes turns yellow and moldy.

In this case, we can remove it with vinegar. Add vinegar and water in a ratio of 1:5, then use a dry cloth or old toothbrush dipped in vinegar and toothpaste to gently wipe the moldy and yellowed areas of the rubber strips.

For white appliances, do not place them in direct sunlight, and at the same time can cover them with a decorative cloth to avoid excessive light exposure, thereby delaying the time for the appliance to turn yellow. If it's already yellow, remember not to let it get darker. When it comes to cleaning the enclosure of a home appliance, people generally think of detergents.

Remind you that there is a corresponding detergent for each material, and if the detergent is not suitable, it may become more and more yellow and even cause more damage to the box. From this point of view, only the use of the right detergent can keep the body as white as possible.
