Promising review: “I was skeptical at first, but after one use, I’m a believer. I had moved into an apartment where both the toilet tanks had what looked like black mold, mineral deposits, and rust. Every time we flushed the toilet, you could smell mold. I had tried multiple products, even draining the tank and trying to scrub it. Nothing worked. After one treatment, only half a bottle per tank, and the tank is pristine, white as can be. All of the mold, rust stains, and minerals are gone. I will continue to buy this product forever! Literally, you pour half a bottle in, stir, wait eight hours, and presto!!!!” —AD
