These work amazing, every problem I have had with stains on counters or in the bathroom come off!
I don't recommend using this on your walls because it strips the paint!
I also recommend keeping this is a very safe place because it is very toxic for children!

I've tried this products and was really surprised by the effectiveness of it. This stuff cleans very well.

I've had problem though on walls that were recently painted. The Magic Eraser got rid of the spill but you still can see a light film on the wall where the magic eraser got applied. I would recommend being careful on freshly painted walls!

Otherwise this is a very good product, that you can get for cheap on sale!

The best thing ever invented .... I love the magic eraser of any kind. It is a magic sponge, as i like to call it. Working in childcare these little erasers do wonders for crayon on the wall or furniture and marker and paint stains ... and now at home with the 14 month old it does wonders. Great product !

We always have these around the house now. They're good for cleaning lots of random things, and hold up to lots of scrubbing before they need to be thrown out.
I've used these mainly to get rid of marks and smudges on walls and other household things - it's pretty amazing to see how much dirt they pick up, that you didn't even know was there!!! Plus I like that they have no scent, and pretty much only require some water to use. (You just have to be careful to use the perfect amount of water or squeeze it all out so the sponge doesn't drip.)
These are definitely good to have around the house.

Love these!! They are absolutely amazing on soap scum in the shower. They save so much time. Sales are out regularly for these and there are coupons out every so often for them as well.

I love the Mr. clean magic eraser, I have kids and scuff marks all the time, so when I use the magic eraser, it takes them all away and you couldn't tell at all.

These are an amazing product. when we bought our house there was an area on our kitchen counter that was coated in......something no clue what it was. I fought for months trying to get up what ever the sticky substance was to no avail. We got to a point where we were going to tear it out and put in a new counter top when my husband suggested trying the Magic Eraser. I hadnt wanted to thinking it might take off the finish but figured we are ripping it out anyways what did it matter. So out came the magic eraser and out came whatever the mess was on our counter! Didnt even have to put any effort into scrubbing it came off like it was water! Now I ALWAYS have magic erasers in my cupboard they really are magic!

Take all kinds of smudges, scuffs and what-not off our white walls! Definitely would recommend these for all sorts of situations, they really live up to their hype.

I love using these erasers that do work great. They do get marker, crayons nail polish, and everything else the boys decide to use on my walls. The only down fall that i found is that if you press to hard or use to much in one spot on the wall it can take off the paint. I have recommend these to all family and firends.

Best invention since peanut butter !!! LOL I use it for a LOT of jobs -- even removes dried paint spattered on wooden door frames !!
