Don't waste your money. Absolutely useless. It's not even a good buffer. As for cleaning. It is best to wipe off with a paper towel. I bought it because of its supposed cleaning power. Since after a few passes the dirt on my tile wouldn't come off with the sponge, I knelt down and used a similar sponge to make sure it wasn't some kind of glue. It's not like this. He came up with some hand scrubs. I bought a mop so I don't have to wash the tiles with my hands and knees. I repeat that this product costs nothing!
