These scrubby sponges work very well for an affordable price. I use these sponges for dishes, the dishwasher, pots, pans, sinks, other bathroom surfaces, and more. I haven't experienced any scratches, I think the roughness is just right. The sponges last for a good month to a month and a half. And if you get them in packs, they're great to stock up on. They're easy to rinse off, and don't keep a stench.
