How to Remove Yellow Stains from Plastic

Yellow stains often appear on plastic caused by food, sunlight or chemical reactions. There are many ways you can try to remove these stains, such as soaking the plastic in bleach, rubbing alcohol, or hydrogen peroxide. If you’d rather scrub than soak, try using lemon juice, salt, or baking soda to remove yellow stains from plastic.

Use rubbing alcohol to dissolve yellow stains. If it’s plastic containers, you can pour alcohol into them and let the alcohol soak for a few minutes. If the plastic item does not hold liquid, you can pour alcohol into another container and soak the plastic in it. ^{[1] X Research Source}

Wash plastic items with soap and water after pouring alcohol on them.
If alcohol is not available, you can also use hand sanitizer instead of alcohol.

Try applying bleach to a small portion of the plastic before soaking the entire item to make sure the bleach doesn’t damage the plastic.

Use vinegar if you’re afraid to use bleach. White vinegar works just as great on plastic as bleach without causing harm. Mix 1 part white vinegar with 1 part water before pouring the mixture into or on top of plastic. Soak the resin in white vinegar for several hours before washing it off with soap and water. ^{[4] X Research Sources}

If you’re trying to remove stains from plastic that won’t hold liquids, pour the white vinegar solution into a container and let the plastic soak in.

Soak in hydrogen peroxide to remove the yellow color on plastic. Hydrogen peroxide works well on yellowed plastic surfaces instead of just a stain. Pour enough hydrogen peroxide into the plastic bag to cover the plastic surface. Put the plastic item in a bag of hydrogen peroxide and let it dry in the sun. Leave for 3-4 hours before rinsing with water. ^{[5] X Research Sources}

You can buy hydrogen peroxide at drugstores.
If you handle plastic machinery, be sure to remove all non-plastic parts before immersing in hydrogen peroxide.
If you want, you can also use an old toothbrush to scrub the hydrogen peroxide on the plastic.
