Sea Glow is great to use on the bottom of your sneakers. It restores and maintains the original snowy whiteness of white plastic and rubber that have become yellowed.

It's easy to use! 

Just apply the Sea Glow with a paper towel (using a scuff pad or a brush helps reach the crevices).  Place in the sunlight to activate the Sea Glow; the longer in the sun, the better.  Take a wet paper towel and wipe off any remaining Sea Glow.

Repeat this process as needed until the yellow is gone.
