Review on 👟 Grandma's Secret Sneaker Cleaner: Powerful Stain Remover Spray for Rubber, Canvas, and Leather Shoes - Effectively Cleans Dirt, Grime, and Grass Stains - Perfect for Outdoor Shoes, Slippers, and Moccasins - Combo, DuoPack by Nicole Thomas

Too bad I didn't take before and after photos. I tripped over a black rubber curb in a parking lot in white canvas sneakers. There was a very dark black stain on the fabric part of the sock. I tried the magic eraser and it didn't work. I thought I needed to buy a new pair of running shoes but went to Revain and found this cleaner. I read the reviews and decided to try it first. I'm so glad I did. I washed the white canvas sneakers before brushing my teeth and they turned yellow. This spray didn't turn them yellow, it made them bright and clear. I can hardly, I mean hardly, find out where the mark was. I sprayed it on, waited a bit, used a toothbrush and then did it again a little later and was very happy with the result. Definitely worth trying if you think you have a lost case like mine!
