Keep two bathrooms fresher with less daily scrubbing. This 2-pack of Mer-Maid Automatic Toilet Bowl Cleaner drops right into the tank and works with every flush.

Just pull the yellow tab and set each bottle upright in the tank. Mer-Maid’s sustained-release formula meters out ultra-strength cleaner that helps break down stains and residue and leaves a light, fresh scent. The signature blue water is your visual cue that it’s still releasing.

Each unit is made to last up to 3 months based on average flushes in a single-person household, so a 2-pack can cover one toilet for about 6 months or two toilets at the same time. It is a maintenance cleaner — not a substitute for periodic brushing — and it is not safe for septic systems.

What’s included: 2 Mer-Maid toilet tank cleaners
How to use: Remove tab → place upright in tank → flush as normal
When to replace: When the water is no longer blue or cleaning weakens

Not for septic tanks. Follow all package instructions before use.
