Review on 🧼 U.S. Pumice Pumie Scouring Stick - Heavy-Duty Powerhouse Pumice Cleaning Bar (2 Pack) by Jennifer Howard

I have tried literally everything on the market to remove streaks and plumbing rings in my toilets (CLR, Bleach, Bartenders Friend, Ajax, Comet and many other ready made toilets cleaner in the form of a gel). There's nothing more frustrating than knowing your toilet is clean but still looks ugly. I tried this pumice stone after reading the reviews. In short, they work in mineral deposits. It took about half a stone to clean my three toilets. Now my ten year old toilets are clean and look clean. Not sure if they work for rust and iron deposits, but for yellowish/brownish calcium type mineral deposits they are the solution.
