Editor's Pick: Hard water stains and yellow buildup around the inside rim and under the rim of the toilet can be tough to scrub away with regular cleaners. This one uses an acidic formula—just pour it in, let it sit for a bit, and stubborn mineral deposits and discoloration start to loosen on their own. The thicker consistency clings to the bowl surface, so you don't have to keep reapplying. It also tackles rust and odors, and won't leave a harsh bleach smell lingering in the bathroom afterward. If you have hard water at home or just want to save yourself some scrubbing effort, this is worth a try.
