How to Clean Yellowed Plastic With Hydrogen Peroxide
Hydrogen peroxide might be the easiest and quickest way to restore your white plastic after it's yellowed. Depending on your specific plastic and the items you have around the house, you might find this method brings back that familiar white without too much elbow grease required.
- Hydrogen peroxide
- Pour straight peroxide into a container.
- Put the plastic in the container.
- Allow the plastic to soak in the sunlight until the stain lifts.
- Rinse and dry.
This method works exceptionally well for cleaning clear cellphone cases.
How to Clean Yellowed Plastic With Bleach
If you don't have hydrogen peroxide, you might have some bleach in your cleaning cabinet. One of the most common ways to clean yellowed plastic is to give the item a bleach bath.
Much like the hydrogen peroxide method, cleaning your yellowed plastic with bleach is pretty easy on the elbows. You can even get some things done around the house while you wait for the bleach to work its magic.
- For electronic parts, remove the yellowed plastic.
- Fill a sink with an 8:1 water to bleach mix.
- Put on some gloves.
- Submerge the plastic in the bleach.
- Soak until white again.
- Remove from the solution.
- Wash with mild soap and rinse.
Safe Method to Whiten Yellowed Plastic Toys
A worn-in toy is just a sign that your child had an absolute blast during playtime. But you might need a safe way to white those yellowed plastic toys.
In this case, you can stay clear of bleach and peroxide. Especially those toys that make their way into a kiddo's mouth. Give the baking soda and dish soap a try for safely restoring your child's favorite toy.
- Baking soda
- Dish soap (Dawn works great for this method)
- Soft bristle brush or toothbrush
- In a container, form a paste with Dawn and baking soda.

Remove Yellow From Plastic With Lemon
The lemon method for removing yellow from plastic is also a safe way of whitening your child's toys. It cleans the item gently and leaves behind a fresh scent, so it's a win for everyone.
- Lemon or lemon juice
- Dish soap
- Bristle brush or toothbrush
- Pour lemon juice into a container. (This can work exceptionally well if it's a yellowing plastic container you need to clean, too.)
- Soak the toy in the lemon juice.
- Allow it to soak for at least an hour in the sun.
- After an hour, put a bit of Dawn on the brush and brush off the toy.

This method can work for small toys and items but will be ineffective for bigger ones.

Spaghetti night is all fun and games until your favorite plastic container goes from crystal clear to yucky yellow. When you have some containers yellowed from food or stains, pull out the white vinegar. This gentle cleaning method is safe for food containers and items that children frequently use.

- Scrub the plastic with the magic eraser.
- Dip and wring out the eraser as needed.

Why Does Plastic Yellow?
Yellowing plastic is a sign of stains or simple aging. For example, yellowing plastic on your Tupperware might be a stain from that spaghetti sauce or leftover chili. However, yellowing plastic on a game console is typically caused by UV light exposure.
The reason behind yellowing plastic may differ from item to item, but overall it's just a sign that the item is being used regularly or is aging as it sits in your home.

With the know-how at hand, you can restore countless plastic items to their original appearance. Find the method that's best for your particular plastic (and your family) and watch the yellow fade to white.
