My toilet tank walls were toally covered with dark brown rust. Put in half can and checked a few hours later and it had already started to remove the rust. By morning all the rust was gone. Fantastic product. Highly recommend this product

The toilet tank cleaner works amazingly well. We put it in the tank before bed and the next morning it had done it's job. We will definitely be purchasing this product again.
