How do I use Loo Cleaner Tabs?Updated 7 hours ago

TL;DR: Drop one Loo Cleaner Tab into the bowl (or cistern tank) and let it soak for 10 to 15 minutes. Leave overnight for heavy soiling. Scrub around the bowl and under the rim with the Loo Blade, then flush. Repeat weekly for a consistently clean bowl. For stubborn build-up on aged bowls, swap the Loo Blade for a Diamond Sponge.

How do I use Loo Cleaner Tabs directly in the bowl?

Drop one Loo Cleaner Tab directly into the toilet bowl. Wait at least 10 to 15 minutes so the tab fully dissolves and the solution breaks down soiling (leave overnight for heavier build-up). Just before flushing, scrub around the bowl and under the rim with the Loo Blade to lift anything loosened by the tab. Flush. Repeat weekly to keep the bowl consistently clean.

✓ Bowl cleaning method

1

Drop one tab directly into the toilet bowl.

2

Wait 10 to 15 minutes so the tab dissolves fully. For heavier soiling, leave overnight.

3

Scrub around the bowl and under the rim with the Loo Blade.

4

Flush. Repeat weekly.


How do I use Loo Cleaner Tabs in the cistern tank?

Drop one Loo Cleaner Tab into the cistern tank (the water reservoir behind the bowl). Allow 10 minutes for the tab to dissolve, then flush to release the solution into the bowl. Scrub around the bowl and under the rim with the Loo Blade, then flush again. The cistern method keeps the bowl freshening between regular cleans and is ideal for households that want a passive top-up routine.

✓ Cistern tank method

1

Drop one tab into the cistern tank.

2

Allow 10 minutes for the tab to dissolve, then flush to release the solution into the bowl.

3

Scrub with the Loo Blade and flush again.


What about heavily soiled or aged bowls?

For heavy, aged, or stubborn surface soiling, follow the bowl cleaning method but swap the Loo Blade for a Diamond Sponge. The abrasive sponge helps lift aged staining that a standard blade won't shift. Let the tab soak overnight for maximum effect. Wear protective gloves when scrubbing with a Diamond Sponge. If soiling persists after two consecutive weekly treatments, the build-up may be limescale, which needs a dedicated limescale remover.

⚠ Use a Diamond Sponge for stubborn build-up

For particularly aged or heavily soiled bowls, swap the Loo Blade for a Diamond Sponge. Let the tab soak overnight first. Wear protective gloves when scrubbing. If soiling persists, the build-up is likely limescale and needs a dedicated limescale remover.

Overnight soak Diamond Sponge Wear gloves

How often should I use Loo Cleaner Tabs?

Once a week for a typical household toilet. That's enough to prevent build-up and keep the bowl fresh without overusing product. High-traffic toilets (shared homes, guest bathrooms) may benefit from two treatments per week. The 14-pack of Loo Cleaner Tabs covers roughly 3 months of weekly use per toilet.

✓ Weekly is the sweet spot

Once a week per toilet prevents build-up without overuse. High-traffic toilets can handle twice weekly. One 14-pack = around 3 months per toilet. Subscribe & Save every 3 months to keep the routine running without thinking about it.
