Yellowed white plastic can be a frustrating eyesore, especially when it comes to household items or even electronics. However, rest assured that there are simple and effective ways to restore the original white appearance to your plastic items. In this guide, we will walk you through the step-by-step process of whitening yellowed white plastic.

What Causes Plastic to Turn Yellow?

Before we delve into the solution, let’s understand why white plastic tends to turn yellow over time. The primary culprit behind yellowing plastic is oxidation. Exposure to UV light, heat, and certain chemicals causes the plastic molecules to break down, resulting in a yellowed appearance.

Materials You Will Need

  • Bleach or hydrogen peroxide
  • Baking soda
  • Clean cloth or sponge
  • Plastic-safe cleaner
  • Protective gloves and goggles

The Step-by-Step Guide

Step 1: Preparation

Start by gathering all the necessary materials and ensuring you are in a well-ventilated area. Put on your protective gloves and goggles to safeguard against any potential hazards.

Step 2: Cleaning

Begin the process by cleaning the yellowed plastic thoroughly. Wipe off any dust or dirt using a clean cloth or sponge and a plastic-safe cleaner. This will prepare the surface for the subsequent whitening treatment.

Step 3: Mixing the Whitening Solution

In a small container, mix equal parts bleach or hydrogen peroxide with baking soda. Ensure you have enough of the mixture to cover the yellowed areas of the plastic.

Step 4: Applying the Whitening Solution

Using a sponge or a cloth, gently apply the whitening solution to the yellowed plastic surface. Make sure to cover the entire area evenly and be cautious not to oversaturate the plastic.

Step 5: Let it Sit

Allow the whitening solution to sit on the plastic for at least 30 minutes. This allows the solution to penetrate and break down the yellowed molecules.

Step 6: Scrubbing

To remove any remaining yellow stains, use a soft-bristled brush or sponge to scrub the plastic. Apply gentle pressure while scrubbing to avoid scratching the surface. Continue scrubbing until the yellowed areas have significantly lightened.

Step 7: Rinse and Dry

Thoroughly rinse the plastic with clean water to remove any residue from the whitening solution. Ensure you remove all traces of the solution. Finally, dry the plastic completely using a clean cloth or by air-drying it naturally.

Step 8: Repeat if Necessary

If the yellowing is still present after the first treatment, you can repeat the process. However, avoid overdoing it, as excessive exposure to bleach or hydrogen peroxide may cause damage to the plastic.

Step 9: Prevent Future Yellowing

To prevent yellowing in the future, it is recommended to store white plastic items away from direct sunlight, extreme temperatures, and harsh chemicals. Regularly clean and maintain the plastic to remove any dirt or substances that could contribute to yellowing.

By following this step-by-step guide, you can effectively whiten yellowed white plastic and bring back their original beauty. Remember to always follow safety precautions and test any whitening solution on a small, inconspicuous area before applying it to the entire plastic surface.
