This is truly a magic eraser! My kitchen cabinets, that are white, had these horrible black marks all over them that I just could not get off! I tried everything and it drove me crazy cause it made them look so ugly. So I thought I'd try these. When I got them I was amazed that they removed all the marks! I was so happy! These things are amazing and my cabinets look like new again! I have to say you really have to work to remove the stains, but it's worth it and they fall apart very easily but they're cheap so no worries, I'll keep buying these and use them all over my house.
