How do I use Loo Cleaner Tabs?Updated 4 hours ago
TL;DR: Drop one Loo Cleaner Tab straight into the bowl, wrapper and all. Let it fizz and dissolve, scrub the bowl and under the rim with the Loo Blade, let the solution sit a few minutes, then flush. Once a week per toilet. For aged bowls, soak overnight and scrub with a Diamond Sponge instead.
How do I use Loo Cleaner Tabs in the bowl?
✓ Five-step bowl method
Drop one tab into the bowl, near the sides so the solution spreads evenly. The wrapper stays on.
Let it fizz and dissolve for a few minutes. The PVA wrapper dissolves with the tab, so there's nothing to unwrap or bin.
Scrub the bowl and under the rim with the Loo Blade. The rim is where build-up starts, so it's worth the extra ten seconds.
Let the solution sit a few more minutes so it keeps working on the surface.
Flush to rinse everything away. Once a week per toilet.
⚠ Don't flush before the tab dissolves
Flushing a partly dissolved tab can clog plumbing and waters down the clean before it's started. Let the tab finish fizzing before you scrub or flush. A cold bowl in winter takes a bit longer, so give it the extra minute rather than rushing it.
What about heavily soiled or aged bowls?
⚠ Overnight soak, then a Diamond Sponge
Same method, longer dwell. Drop the tab in last thing at night and leave it, then scrub with a Diamond Sponge instead of the Loo Blade. The fine abrasive lifts aged staining the blade won't shift on its own. Wear protective gloves. If the marks survive two weekly treatments, you're most likely looking at limescale from hard water, and that needs a dedicated descaler rather than more tabs.
How often should I use Loo Cleaner Tabs?
✓ Once a week per toilet
Weekly stays ahead of build-up rather than chasing it. A busy shared bathroom or guest loo can take a second tab in the same week. One tab per weekly clean means a pack runs around 3 months on a single toilet. Two toilets on the same routine share the pack, so it runs about 7 weeks.
Can I put a tab in the cistern instead?
✓ Cistern method, four steps
Drop one tab into the cistern, the water reservoir behind the bowl.
Allow around 10 minutes for the tab to dissolve fully in the cistern water.
Flush to carry the solution into the bowl, then scrub with the Loo Blade.
Flush again to rinse. The bowl method is still the one to use on visible soiling.
One caveat worth respecting: if your cistern or flush valve carries a manufacturer warning against in-tank cleaning products, follow the manufacturer and stick to the bowl method.
Does the routine change on a septic or greywater system?
✓ Same method, three rules
Use only as directed. One tab per toilet per week suits a typical household.
Never pour undiluted product straight into a septic tank, greywater line or inspection opening.
Avoid excessive use beyond normal cleaning. More product doesn't clean better and it loads the system.
Loo Cleaner Tabs are septic compatible when used as directed. There's no chlorine bleach and no quaternary ammonium disinfectant, so the bacteria your system relies on aren't disrupted. Septic tanks, AWTS, greywater and caravan cassette toilets have their own article in this cluster, linked below.
⚠ If you irrigate with treated water, three things change the answer
Greywater reuse isn't only about the product. It depends on your soil type, since clay and sandy soils handle irrigation water differently. It depends on what you're watering, because edible crops carry stricter rules than ornamentals. And it depends on your local council, since requirements vary by state and council area. Check your local guidelines, and treat your system manufacturer's approved-product list as the final word.
Individually wrapped tabs, around 3 months on one toilet. Septic compatible when used as directed, with no chlorine bleach. Drop in, scrub, flush.
