How do I use Loo Cleaner Tabs?Updated 13 days ago

Drop one Koh Loo Cleaner Tab directly into the toilet bowl, ideally near the sides of the bowl so the dissolving solution distributes evenly. Wait a few minutes for the tab to dissolve and fizz fully. Scrub around the bowl with the Koh Loo Blade, paying attention to anything visibly soiled. Let the solution sit a few more minutes, then flush to rinse the cleaner away. Repeat weekly per toilet to prevent build-up. Avoid flushing before the tab has fully dissolved, which can clog plumbing and reduces the cleaning result. The PVOH wrapper does not need to be removed and dissolves with the tab.

For aged, heavily-soiled, or stubborn surface staining, follow the same bowl method but soak the tab overnight rather than for a few minutes. The longer dwell time gives the oxygen-based bleaching agents and enzymes more time to break down protein, mineral, and organic deposits. Then scrub with a Koh Diamond Sponge instead of the Loo Blade. The fine abrasive on the Diamond Sponge lifts aged staining that the Loo Blade won't shift on its own. Wear protective gloves when scrubbing with a Diamond Sponge. If soiling persists after two consecutive weekly treatments, the build-up is most likely limescale (mineral deposits from hard water), which needs a dedicated descaler product to remove fully.

Once a week per toilet is the sweet spot for a typical household. Weekly use prevents build-up before it starts, keeps the bowl visually fresh, and avoids overuse of product. High-traffic toilets (shared houses, guest bathrooms, busy family homes) may benefit from two treatments per week. The 14-pack covers around 3.5 months at one tab per week per toilet, or approximately 2 months for an average household with multiple toilets running on the same routine.

As an alternative to the bowl method, drop a Koh Loo Cleaner Tab into the cistern tank (the water reservoir behind the bowl). Allow around 10 minutes for the tab to dissolve fully in the cistern water, then flush to release the cleaning solution into the bowl. Scrub around the bowl with the Koh Loo Blade, then flush again to rinse. The cistern method works as a slow-release top-up between regular bowl cleans and is ideal for households that want to keep the bowl freshening between active scrubs. The bowl method is still primary for visible soiling, since the dissolved solution stays in direct contact with the soiled surface for the full cleaning window. Either method is fine. Choose based on your routine.
