Think:  Sandpaper
These are amazing.  What I didn't know is that they are equivalent to fine grit sand paper, especially when wet or when you use a fair amount of pressure, so be mindful of the surfaces you use them on.  I was thinking about trying to clean bugs off my car windows and the small areas of rust off my cars, but more reading on it helped me decide that was not a good plan.  They're great around the house, though.
