Does sunlight turn plastic yellow?

Yes, exposure to sunlight can indeed cause plastic to turn yellow. This is due to the process of photo-oxidation, where the UV component in sunlight leads to the yellowing of plastic. The UV rays initiate a reaction that causes oxidation in the plastic, resulting in the yellow discoloration over time. Therefore, prolonged exposure to sunlight can gradually turn plastic yellow.

What whitens yellowed plastic?

One effective way to whiten yellowed plastic is by using a mixture of hydrogen peroxide and baking soda. Simply combine equal parts of hydrogen peroxide and baking soda to form a paste. Then, apply the paste directly onto the yellowed plastic, making sure to cover the entire surface. Let it sit for a few hours or overnight, and then rinse off the paste with water. This method is particularly useful for smaller items that cannot be submerged in a bleach solution.

Another alternative method is to use a mixture of vinegar and sunlight. Create a solution by mixing equal parts of white vinegar and water. Submerge the yellowed plastic in this solution and let it soak for several hours or overnight. After that, place the plastic item under direct sunlight for a few hours. The combination of the vinegar and sunlight helps to break down the yellowing agents and lighten the color of the plastic. Rinse off the plastic with water afterward to remove any vinegar residue.
