Question

Just curious, there were some stains on the tile in my bathroom that an ordinary sponge wouldn’t get out, but a magic eraser got rid of with ease!

I thought I read where it’s a microscopic abrasive. I think it’s the structure of the eraser. It’s called melamine foam and u can look it up in WIKI.
