Introduction
Over time, the white plastics of home appliances tend to turn yellow due to the effects of ultraviolet (UV) light, heat and contact with chemicals. This aesthetic wear and tear can give the impression that the appliances are old, even if they still work perfectly.
However, it is possible to reverse this yellowing with a simple technique, using easily accessible homemade products. Below, you will learn how to give your appliances a renewed appearance.
Necessary Materials
- 10 volume hydrogen peroxide (hydrogen peroxide)
- Baking soda
- Neutral soap or detergent
- Rubber gloves
- Used brush or toothbrush
- Plastic film (film)
- Container for mixing ingredients
- Clean, dry cloths
- Safety glasses (optional)
- Mask (optional)
Step by step
1. Surface Preparation
- Cleaning: Start by cleaning the yellowed area with mild soap and water. Use a clean cloth to remove dirt, dust, and grease. Make sure the surface is completely dry before proceeding.
2. Preparation of the Whitening Paste
- Mixture: In a bowl, combine the hydrogen peroxide with the baking soda until you get a consistent paste. The ideal ratio is 1 part baking soda to 2 parts hydrogen peroxide.
3. Applying the Paste
- Protection: Put on rubber gloves to protect your hands.
- Application: Using a brush or toothbrush, apply the paste evenly over the yellowed areas of the plastic, covering all affected areas.
4. Cover with Plastic Film
- Sealing: After applying the paste, cover the area with plastic wrap. This helps to maintain moisture and enhance the whitening effect.
5. Exposure to Sunlight
- Whitening: Move the item to a location where it can receive direct sunlight. Exposure to UV light speeds up the bleaching process. Leave it on for 3 to 6 hours, checking the progress periodically.
6. Finalization
- Cleaning: After the exposure time, remove the plastic film and wash the area with water and mild soap to remove any residue from the paste. Dry thoroughly with a clean, dry cloth.

This homemade technique is an effective and affordable way to restore the original color of yellowed plastics in household appliances. By following the steps correctly and taking the necessary precautions, such as wearing gloves and eye protection, you can restore the appearance of your appliances, extending their useful life and keeping them visually appealing.
