They work great! However, they can be pricey. You can buy sponges that are the identical material as the Magic Eraser online for as little as $0.29 per sponge with free shipping!

These things work on everything! Love using them in the shower to get the hardened stuff off the bottom of the shower or around the edges. I just leave it in there, wet down and scrub away.

Great for cleaning the tub and the hard to clean shower door. Helps get grime. Only complaint is when the eraser starts to flake apart with vigorous scrubbing.

Cleans things like new that you would never think would be clean again. Mandatory for spring cleaning!

It is 'MAGIC'!! For on the spot cleanups of scuff marks on your walls & patio furniture this little eraser works amazingly.
The only issue for walls it cleans too well if that makes sense. I usually have to do a whole section so it's all bright & clean. As cleaning one spot that's marked makes a noticeable cleaner difference.

You wet the eraser a little & it goes a long way. No need to rub too hard.
My household is fully satisfied with Mr Clean Magic Eraser (all Mr Clean products tbh) that we buy it & the heavy duty new one quite often.
We are a family with 3 children so there is lots to clean up & my kids actually enjoy using the magic eraser, which is a bonus as it's their 'mess' on the walls! ;-)

I use the Magic Eraser to clean my baseboards mainly and greasy fingerprints on my walls. Amazing! Doesn't require much elbow grease and really effective. Just don't be too enthusiastic with your scrubbing though, you can take the paint off your walls! )

This is one of the best products on the cleaning market today! I very much recommend this product for stubborn marks on walls (crayons, markers and scuff marks)

It works really well for a majority of mishaps. I just don't like how it crumbles into small bits after awhile. It leaves them everywhere

Un produit qui fait maintenant parti de ma vie. Efficace sur quasi toutes les surfaces, il fait presque des miracles. J'ai réussi à faire disparaître des taches que rien d'autre n'avait fonctionné. Ma dernière découverte, il est génial sur le pvc blanc de la piscine.

I have used Mr Clean Erasers for so many things.. and each time I am blown away by how well it performs. It started out because I had young children... crayons, markers... fingerprints, were no match for MCE. Then I took them outdoors.. patio furniture looked new! I have even used this on the inside of my fish tank to get algae off. I had some people freak and say it would kill my fish, but it didn't.. and I did it for years.
Makes life easier.. and I am all about easier!
