Review on Universal Stone - Eco-Friendly All-Purpose Stone for Foam Cleaning, Polishing, Protection. Includes Sponge. Biodegradable Formula (650g) by Lori Harper

It's amazing! I can't say enough good things about him! I'm amazed at how well this works! First, it won't remove the burnt part from the oven, but it will remove everything else. Walk on mud, not mud. If it's something that needs to be "cut," you still need to do it. But boy is it great on dirt you didn't think you could clean! I tried it on my grout between the marble tiles in the bathroom. Nothing else worked. I've been trying since we bought the house, they were just stained. But I tried, a little swipe and they are white again! I was shocked! I thought I needed to paint my white fiberglass garage door, it had weird stains on it. nope Just needs a good cleaning. It will take a while but it will look brand new! Nothing else worked, I thought it was just old. It is great! It's fun to find new uses!
