Looking to get rid of those pesky yellow stains on your white plastic appliances? Here’s a quick and easy guide on how to whiten yellowed plastic and make your appliances look good as new!
To whiten yellowed plastic on appliances, you can try using a mixture of baking soda and water. Mix the baking soda and water together to form a paste, then apply the paste to the yellowed areas of the plastic. Use a soft cloth to rub the paste into the plastic, working in circular motions. Rinse the plastic with water and dry it with a clean cloth.
This method should help to restore the plastic to its original color. Alternatively, you can try using a commercial plastic whitener, which can be found at most hardware stores. Follow the instructions on the product label for the best results.

Plastic appliances, such as kitchen utensils, bathroom fixtures, or electronic devices, can become discolored and develop a yellowed appearance over time. This can be caused by a variety of factors, including exposure to sunlight, aging, or chemical reactions. However, there are several simple and effective methods you can use to whiten yellowed plastic and restore its original color.
