Yellowing plastic on appliances is a common problem that can make your kitchen look dirty and unhygienic. Fortunately, there are effective ways to brighten these plastics and restore their original appearance. Below, we’ll explain in detail how to brighten yellowing plastic on appliances using simple methods and readily available products.

What causes plastic to yellow?
Plastic turns yellow when exposed to sunlight, heat, and air over time. These factors degrade the plastic over time, causing it to yellow and age. Appliances like microwaves, refrigerators, and washing machines are more susceptible to this phenomenon because they are used frequently and are often found in kitchens.

Products Needed
To restore the yellowed plastic of your devices to white, you will need a few basic items:

Hydrogen peroxide (40 parts by volume): Strong bleaching agent.
Plastic foil (PVC): To cover the treatment area.
Brush or cloth: To apply the hydrogen peroxide.
