Things You'll Need
Instructions
Submerge the yellowed item in a bucket filled with equal parts of water and bleach.
Wait an hour or longer until the bleach has removed the yellow color. You don't need to do anything else here; just let the toy soak.
Remove the toy from the bucket.
Wash the bleach from the toy using dish detergent.
Dry the toy with a dish towel.
Gently rub superfine sandpaper along any areas that remain yellow.
Wipe the toy with a soft cloth to remove any dust from the sanding.
