This stone seems to be softer than the one I've used before because the stone wears out faster. I'll try a different pumice stone next time. I have used pumice stone to remove scale stains in toilets for many years. They work. You must take care to keep the stone very wet during use. Soak it in water, rub it a few times, and then soak it again, otherwise you will get scratches.
