Do Loo Cleaner Tabs have a fragrance?Updated 13 days ago
TL;DR: No. Loo Cleaner Tabs are fragrance-free. No added perfumes, no synthetic scents, no masking agents. The formula is Sensitive Choice approved. If you prefer an added scent, drop 2 to 3 drops of essential oil into the bowl alongside the tab. Eucalyptus, lemon-scented tea tree, and lavender are popular picks. Never add essential oils to the cistern tank.
Are Loo Cleaner Tabs fragrance-free?
✓ Nothing added to hide anything
No perfumes. No masking agents. No synthetic scents. The oxygen-based formula is inherently low-odour, so there's nothing to mask. Sensitive Choice approved by the National Asthma Council of Australia. GECA eco-certified.
What does the bowl smell like during cleaning?
✓ Faint clean fizz, nothing harsh
The fizzing smells fresh and mineral, like sparkling water, not chemical or perfumed. Once flushed, the bowl is left with no lingering scent. If you're used to bleach-cleaner smell, the absence of strong scent can take a few cleans to feel normal.
Can I add a scent to the Loo Cleaner Tab?
✓ How to add a scent
2 to 3 drops of essential oil into the bowl alongside the tab. Koh's three options are Eucalyptus Oil, Lemon Scented Tea Tree Oil, and Lavender Calm Essential Oil. Add to the bowl water only. Let everything dissolve, scrub, sit, flush.
Can I add essential oils to the cistern tank?
⚠ Never add essential oils to the cistern tank
Oils don't dissolve in water and can build up on rubber seals, flapper valves, and fill valves inside the cistern, leading to leaks and running toilets. Note: the tab itself is fine in the cistern (it dissolves cleanly in water). Oils are not. Keep oils in the bowl only.

Fragrance-free. Sensitive Choice approved. GECA eco-certified. Add your own scent in the bowl if you want one.
