Clorox Tough Stain Remover does the thankless job it's made for and does it well. I won't say there isn't a little elbow grease involved, but it's not as bad as trying to remove hard water stains with other cleaners can be.
If you have hard water then you know how fast a toilet bowl can turn grimy. Leave in products hardly stand up to it at all. Luckily there's the Clorox. I usually let it set in the bowl for a little while before scrubbing. It removes hard water stains better than any other product I've tried. The bottle is conveniently shaped with the nozzle at an angle, making it easy to squirt around without reaching an entire arm into the bowl.
It removes unpleasant smells from the toilet and leaves it deodorized. I've smelled more pleasing toilet bowl cleaners than this one, but the scent is not my primary concern when using this cleaner so I'll say it smells as well as it needs to smell.
Squeeze a few ounce of Clorox Tough Stain Remover Toilet Bowl Cleaner into the toilet bowl and let it do its magic. The formula is capable of killing 99.9% of the germs in the toilet bowl, totally removing dirt and grime, and delicately dissolving tough to remove stains, resulting in a sparkly bright toilet bowl.
