While I don't know what scary chemical is in this product, I recommend it ALL THE TIME! It gets the most stubborn stains out, no problems. It works great out outdoor patio furniture in the spring, stubborn marks on walls, etc. If someone mentions they have a stubborn stain and have tried everything to get it out, I suggest the magic eraser.
The one complaint I have, is that I'm very sensitive to tactile products and I do not like the feel of the sponge so I have to wear gloves while using this. Given that it takes out anything, whatever the chemical is, I'm sure that's probably for the best anyhow!

Work well for marks on walls and stubborn furniture!!

I love the Mr Clean Magic Eraser! I find it get stains off of things that I could not get off before, like dog slobber ( (I have a boxer who likes to slobber a lot) finger marks off walls, stains on our white leather boat seats, fridge stove.....etc.

Works great on outdoor furniture

Mr. Clean Magic Erasers are pretty darn impressive. The first time I used one I could not believe how easily marks came off of my wall. Seriously, I was not expecting them to work quite that well. There were a few marks on the wall from moving in and within minutes they were all gone, with no hard scrubbing required. The only little complaint that I have is they do tend to leave a bit of gritty residue on the wall but that's easy enough to wipe off with a damp cloth.

Such a great product.....its also great for cleaning the outer surface of my fridge and stove!!

Good for white walls but if could take off some paint if used too much or used on cheap paint.

LOVE LOVE LOVE !!!
I do all my white walls with these, as it just brings the whines out so well !
My favorite product !
WISH THEY WERE BIGGER THO ! So we could cut them to our own size as the pads they give me I end up cutting in half so I don't waste the middle of the pad ! But I need at least 3 boxes to do my Entire kitchen, out side of cabinets and the fridge and walls .

I always use the magic eraser when I have a tough stain on a hard surface. It works so well and really is magic. I alway have at least one on hand for any tough spots that I need to clean.

Mr. Clean Magic Eraser works pretty well. There is still some stuff that it won't get rid of, but for the most part it does what it's supposed to.
