Iron OUT Automatic Toilet Bowl Cleaner is a drop-in tank tablet that releases cleaning agents with every flush to prevent rust and hard water stains. Each tablet is claimed to last up to 45 days, and the formula is marketed as safe for toilet components, plumbing and septic systems. It is a maintenance product, not a stain remover: Iron OUT itself says heavy rust needs its powder or spray first. That puts it against other in-tank tablets and rim-hanging cleaners, which are easier to place but often shorter-lived and scented.

Iron OUT Automatic Toilet Bowl Cleaner is a set of concentrated tablets that helps keep a toilet bowl clean and free from rust stains. The formula is unscented. It will not harm toilets, internal components, plumbing, or septic systems.
To use, drop a tablet in the toilet tank. For severe rust stains, treat first with Iron OUT powder or liquid spray, then switch to the tablets for ongoing maintenance. The tablets also help prevent rust and hard water stains.
