Works great for cleaning black marks on bats used at batting cages
I got a new bat which was mostly white.  Using it at the batting cages put tons of black marks all over it (from the yellow balls that get a bunch of "junk" on them).  It doesn't really hurt anything, but it did make the bat look pretty bad.  A rag, soap, and water didn't take them off (at least not easily).  These Magic Erasers took off all of the black marks with ease.  The bat looks brand new again.
