These are amazing. They can make showers, tile, sinks, and walls look brand new. I even had some coffee stains on white marble, and a couple of minutes of rubbing with a Magic Sponge got them out.
These are great at cleaning random marks off of my white apartment walls. Whether it is scuffs from my dog kicking the wall when he runs around, or black marks left from picture frames, these clean them right off.
Best thing that was invented, I use it for so much, also to clean the outside of the home or garage. The use for it are endless. Works great.
The only thing I've found that removes smudges from painted walls without leaving a mark. thumbs up!
I wish I had taken a before picture, but two of these saved an awful looking tub that we thought we'd either have to buy expensive chemicals to clean or we'd have to get it reglazed. I decided to try a magic sponge I bought to get a stain out of my countertop and it did an amazing job! I used the remaining two to clean my whole kitchen with and just ordered a new box!
