I have no idea what's in the Mr. Clean Magic Eraser but it sure does a great job in cleaning everything. I've tried it on my kitchen sink and it sparkles after using the Magic Eraser. I've even tried it on my dirty white shoes and they're nice and clean afterwards.

Best invention ever. I have kids and it removes all kinds of dirt

These are an amazing invention , they have so many uses, floors , appliances , doors , cupboards , bathrooms ,motorcycles, etc.
They clean everything with ease, you won't find a better cleaning product . I always have a box of these in my cupboard .

I use the magic eraser all the time.It works on everything.Its amazing

When it first came out I thought it was a hyped up scam like most 'magic' cleaning products, but after using it I found out that it's claims were all real. it really does do wonders and cleaned off marks that nothing else could remove.

Mr. Clean Magic Eraser is the cleaning product underneath most peoples bathroom and kitchen sinks.
The fact that it is so versatile and can be used on anything in and around the house is what makes it extremely popular.
I find it very effective for marks on the walls, kitchen and bathroom tiles full of dirt and grime, around the bathroom tub where a ring begins to form, yeah I know gross but it happens, especially if you do not clean your bathroom for a while. I find it fascinating how a little sponge takes away that many stains, crayon marks on walls, juice and beverage that has spilt and splashed on the walls, I was able to remove Fruit Punch from the walls with just soaking the sponge in water and it out was gone. I would not use it to overall clean your entire walls as it does leave streaks just take out smudges, finger print, and tough stains on walls because it is the safest product you can use on your walls, it will not damage or chip paint away like many chemical products In out there in the market.
It can be priced reasonably usually it does not go on sale but it is definitely worth the time and effort scrubbing and chipping he paint on the walls away as well the versatility you can never go wrong. I love it.

Great way to clean permanent marker off of surfaces. These clean everything

I love these! I used them to clean the entire house basically when I first moved in. It really does get up all the grime and break down build up!

Works great to take any scuff marks or pen or marker type marks off of the walls. I did notice that it will take paint off if you aren't careful.

I had scuff marks on my walls that I really thought I'd have to paint over but I figured I'd try the Mr. Clean Magic Eraser first and see what happened.... well, am I ever glad I did! I didn't need to repaint anything but I did need to buy a couple more Magic Erasers because once I got started, there was no stopping me.

My biggest success with the Mr. Clean Magic Eraser was the ability to get rid of the dog spittle/nose prints that were all over my walls. (Big dog, what can I say?) Now, I've washed walls - correction - SCRUBBED THE HELL out of my walls to get the dog spit off of them before but Mr. Clean, you made it easy!

If only they sold Mr. Clean Magic Erasers in SHEET size!
