Over time, certain plastics that were once white and bright begin to acquire a yellowish tone that makes them look old and poorly cared for. Switches, commands or electrodomers are frequent examples of this phenomenon that does not always disappear with usual cleaning.
Anyone who has tried to remove this yellowing knows that it is not always easy. There are those who rub frequently and energy, but to no avail. However, there is a simple solution that allows you to recover the original look effectively.
The causes of yellowing
According to the portal, there are several factors that explain this visual wear. Ultraviolet light, for example, breaks chemical bonds in plastics, triggering the photodegradation process.
Heat also contributes, causing chemical reactions such as oxidation. The combination of heat and air oxygen alters the plastic structure, favoring color change.
Not all plastics are equal
The quality of the material influences the speed with which it is degraded. Plastics with less impurities and better additives resist more time for natural wear.
Products that can make the problem worse
Certain cleaning products, such as chlorine or ammonia, also affect the appearance of plastics. Its frequent use can accelerate yellowing.
Dirt as an ally of discoloration
Elements such as dust, fat or tobacco smoke can adhere to surfaces and intensify the yellow tone, even if the plastic itself is not damaged.

The trick that is being successful on social networks
Influencer Alejandra Pez shared Instagram an effective trick: apply cream hydrogen peroxide with a brush and cover the zone with adherent film for 24 hours.
The liquid version of hydrogen peroxide evaporates rapidly, becoming ineffective in this context. The cream formula is more stable and easy to apply, being used in hairdressers and available in pharmacies or supermarkets.
The process may require repetitions
A single application is not always sufficient. “Depending on how yellow you are, you should repeat the process several times,” recommends Alejandra Pez.
Important precautions to take into account
Before you start, it is essential to clean the surface well and wear gloves. Cream hydrogen peroxide is abrasive and should be handled carefully to avoid injury or damage to tissues and materials.
How does this chemical reaction work?
Hydrogen peroxide is decomposed on hydroxyl radicals, reactive particles that neutralize the yellow molecules caused by plastic degradation.
Interestingly, the same UV light that contributes to the problem can also help solve it. Exposure to light during the process accelerates the action of hydrogen peroxide.
Other uses of hydrogen peroxide
In addition to lightening plastics, hydrogen peroxide serves to disinfect surfaces, treat stains on tissues, sterilize food and even eliminate odors such as cat urine, especially if combined with sodium bicarbonate.
