Can I use Bathroom & Shower Cleaner on the toilet bowl?Updated 13 days ago

TL;DR: Yes, above the waterline. Bathroom & Shower Cleaner handles the seat, lid, rim, under-rim, bowl walls, base, and exterior of the toilet. For below the waterline (where the product would dilute and flush away), use Loo Cleaner Tabs instead. Scrub with Loo Blade, flush, and you're done.

How do I clean the toilet bowl above the waterline?

Spray Bathroom & Shower Cleaner onto the seat, lid, rim, under-rim, and the bowl walls above the waterline. Let the foam sit for a few minutes to break down grime. Scrub around the bowl and under the rim with Loo Blade. Wipe the seat, lid, and outside of the toilet with a damp cloth. Flush. This method handles everyday cleaning and light build-up in one pass.

✓ Above the waterline, 4 steps

1

Spray the bowl. Seat, lid, rim, under-rim, and bowl walls above the waterline. Cover the area.

2

Let the foam dwell. A few minutes to break down grime and any mineral staining.

3

Scrub. Loo Blade around the bowl and under the rim. Damp cloth for the seat, lid, and exterior.

4

Flush. Clears any rinse water and loosened grime from the bowl.


What about below the waterline?

Use Loo Cleaner Tabs instead. Spraying Bathroom & Shower Cleaner into water below the waterline just dilutes the product, so it doesn't do much. Loo Cleaner Tabs are designed to sit in the water and dissolve over time exactly where you need them. Drop a tab in, let it soak (10 to 15 minutes for light soil, overnight for heavy build-up), scrub with Loo Blade, flush.

✓ Below the waterline

Drop a Loo Cleaner Tab into the bowl. Let it soak (10 to 15 minutes light soil, overnight for heavy build-up). Scrub with Loo Blade. Flush. Designed to work in water, where Bathroom & Shower Cleaner can't.

How do I get a full bowl clean?

Combine both products. Drop a Loo Cleaner Tab in to soak while you work on the rest. Spray Bathroom & Shower Cleaner on the seat, lid, rim, under-rim, and exterior. Let both dwell for 10 to 15 minutes. Scrub everything with Loo Blade (above and below the waterline). Wipe the exterior with a damp cloth. Flush. That's the full toilet clean in one session.

✓ Full toilet workflow

1

Drop the tab. Loo Cleaner Tab into the bowl. Let it soak while you work on the rest.

2

Spray everything else. Bathroom & Shower Cleaner on the seat, lid, rim, under-rim, and exterior.

3

Dwell 10 to 15 minutes. Both products work at once. The tab soaks below the waterline, the foam clings above.

4

Scrub above and below. Loo Blade handles both zones. Damp cloth for seat, lid, and exterior.

5

Flush. Done. Full toilet clean in one session.
