I do however recall something in regard to NOT using it with bleach if I am not mistaken. I will have to look at the box again when I get home.

*edit* found the information on the website
--The Mr. Clean Magic Eraser is a highly effective cleaning tool. Test first on an inconspicuous spot with light pressure to see if surface may scratch or dull. Not recommended for use on surfaces that are polished/glossy, or on brushed, satin, dark, or faux finishes. Do not use with chlorine bleach.--

Are they referring to the bleach being full strength or is the residual enough to cause concern?
Well, ususally when you clean with bleach it is diluted in a bucket of water, not used full strength.
