How do I clean the Loo Blade?Updated 10 days ago

TL;DR: Hold the Loo Blade head over a drain and pour boiling water from the kettle over it, slowly, with rubber gloves on. The heat and the flow carry off whatever the flush left on the blades, so there is nothing sitting there to smell. Let it air dry, then stand it back in the ceramic pot. Once a week suits most homes.

How do I clean the Loo Blade head?

Hold the Koh Loo Blade head over a drain, then pour boiling water from the kettle over it slowly and steadily with rubber gloves on. The heat and the flow lift the film a cold rinse leaves behind, so nothing is left on the blades to smell. Let it air dry, then stand it back in the ceramic pot.

✓ The kettle method, in three steps

1

Hold the head over a drain. The toilet bowl works, so does a sink or a bathtub drain. Somewhere the water can run straight away.

2

Pour boiling water over it. Straight from the kettle, slowly and steadily, so the water runs through the blades rather than bouncing back at you.

3

Air dry, then put it away. The flexible head sheds water quickly. Once it stops dripping, stand it back in the ceramic pot.

✓ Why boiling water is enough

Nothing sticks to the flexible head the way it does to bristles. A swipe of hot water at pressure lifts the film that a cold rinse leaves behind, and once that residue is gone there is nothing left on the blades for an odour to come from. No detergent, no bleach.


How often should I do it, and what if it starts to smell?

Once a week suits most households, with a quick rinse in the fresh flush water after each use in between. If the Koh Loo Blade starts to smell, residue has built up where the head meets the handle or in the base of the pot. Pour the kettle over the head, rinse the pot, and let both dry fully before reassembling.

✓ How often

Once a week covers a normal household, and it fits neatly onto the end of your weekly bathroom clean. A rinse in the fresh flush water after every use is enough in between.

✓ If it starts to smell

An odour means residue has built up somewhere, usually where the head meets the handle or in the bottom of the pot. Pour the kettle over the head, tip the pot out and rinse it too, then let both dry fully before they go back together. Water trapped under a wet head is the usual culprit.

What should I watch out for?

Wear rubber gloves, pour slowly and steadily, and keep the head low over the drain so the water cannot splash back. Keep children and pets out of the room. Chlorine bleach can degrade the flexible head of the Koh Loo Blade over time, so leave it out of the routine and stick to boiling water.

⚠ Handling boiling water

Wear rubber gloves and pour slowly and steadily. Keep the head low over the drain so the water has nowhere to splash, and keep children and pets out of the room while you do it.

⚠ Keep bleach off the head

Chlorine bleach can degrade the flexible head over time, so leave it out of the routine entirely. Boiling water and a rinse are what the head is designed for. Loo Cleaner Tabs are the product to pair with it in the bowl.

What replacement heads and accessories are there?

Koh Loo Blade Head is the replacement head, sold on its own, and it pushes straight onto the handle you already own. If the blades have gone soft or splayed, cleaning will not restore them and a fresh head is the fix. Koh Loo Blade Rim Cleaner attaches to an existing Loo Blade and takes the same kettle rinse.

When a rinse is not enough

If the blades have gone soft or splayed, cleaning will not bring them back. Loo Blade Head pushes straight onto the handle you already own. Pop the old one off, push the new one on.
