Magic Eraser: Removes Anything. But Leaves Residue By ohthethinksyouwillthink on - Updated Oct 15, 2011
It was one of my finer blonde moments...
I needed to make a mural for the kid's club I volunteer at. I got my hands on an old overhead projector, stuck the poster paper to the wall, and proceeded to trace out my pattern--with a black permanent marker. When all was said and done, I took down the paper to discover that the marker had bled through the thin poster paper in some spots (Duh!), and had decorated my cream-coloured wall with black polka-dots. AHHH!
I figured it was the ideal time to try the new Magic Eraser I'd been hearing so much about.
I wet the sponge, wrung it out, and began to scrub. I could not believe my eyes! The magic eraser was taking black permanent marker off the wall! My wall now looks good as new! I smelt a 5 Star Review!
Later that evening, I discovered a white powder on my shoulder. Where'd that come from? I remembered that I had leaned up against the wall, so I went back to the area I had cleaned and ran my hand over it. My hand was covered in a chalky residue! But all was well. A damp rag cleaned up the chalkiness, and now my wall looks and feels as good as new.
The moral of the story? Use a pencil next time! (And also, Magic Eraser is amazing--just remember to rinse when you are done.) =)
Mr. Clean Magic Eraser

Yes, I found this too...actually my hubby loves these for his tires - and he wondered why they had white on them...whatever the stuff is in the eraser it does have to be rinsed :) Thanks for the info
Scotch makes one too. I've used both, but the Scotch brand seems to work better for me-just what you mentioned about the residue. Mr. Clean puts some additives in there. Either way I love these things.
Very useful tool for the house and kids hand prints.
Ooh sounds good. I just bought my first ones. I hope it works on commodes and plastic shower stalls! I hope it doesn't scratch!
This sounds like a good item to have around the house. I always wondered if it worked.
These things are great! I've used it dry on mirrors and it works.
