Review on Dr.WOW 21 Pack Extra Thick Magic Sponge - Best Price Melamine Sponge for Kitchen Air Fryers, Bathroom, Office - 2X Thicker, 2X Longer Lasting Cleaning Power - Effective Eraser Sponge by Erin Abbott

I don't know what other people are complaining about. Yes, just like branded and real erasers, they will wear out and shrink as you use them. And yes, just like Mr. Clean, they can leave residue or small particles, but you can easily wipe them off with a damp cloth. If your eraser gets dirty, I find it best to just spray it with a kitchen sprayer. I do a deep clean in a smoke house and they work great removing stains and tar/nicotine from walls, doors and baseboards. In my actual testing, they last as long, if not longer, than Mr. Clean and cost a lot less. Next, I take sheets as they are great for small or dirty items.
