Review on 🧽 Durable Melamine Sponge 50 Pack: Powerful Magic Cleaning Sponges for All Surfaces - Kitchen, Bathroom, Furniture, Leather, Floor and Walls! by Susan Cox

I've read reports of crumbling but haven't seen any crumbs and I've scrubbed pots and even the kitchen floor really hard. It is great. I thought they were just cute white styrofoam sponges, but now that I understand what melamine foam is and how it works, I understand how they can "erase" all sorts of things, like things stuck to an egg, or as little as the amount of rust that can form on wet knives or even a magic marker on a countertop. I scrubbed my clean sink very hard/well and saw the invisible, ultra-small food residue left by the nylon mesh scrubber. 50 of them for $9 is a great deal.
