Guide to Making Yellowed Plastic White Again

1. Getting Ready
Wear rubber gloves to keep your hands safe. Clean the yellowed plastic surface with a damp cloth to remove dirt and dust. This allows the hydrogen peroxide to work directly on the plastic.

2. Using Hydrogen Peroxide
Apply a generous amount of 40-volume hydrogen peroxide to the yellowed area using a brush or cloth. Spread it evenly across the surface.

3. Putting Plastic Wrap on Top
Cover the treated area with plastic wrap to keep the peroxide in contact with the plastic and prevent it from drying out too quickly.

4. Being in the Sun
Place the appliance or plastic part in direct sunlight. Sunlight boosts the whitening effect. Leave it in the sun for about one hour.

5. Taking Off the Plastic Wrap and Cleaning
Remove the plastic wrap and wipe off any remaining peroxide with a damp cloth. Repeat the process if necessary until you reach the desired result.
