I have loved these scrubby sponges for years - they get through VERY tough grime really well. When I got All Clad cookware, I stopped using them for my dishes, in order to avoid scratching the stainless steel. I still use these to clean my bathroom, but I need to be VERY careful. The green scrubby side can stain my white caulk around the tub. It still does an amazing job of cleaning grout and soap scum, but wherever there is caulk, I need to use a white scrubby sponge.
