TL;DR: No. Loo Cleaner Tabs are fragrance-free. No added perfumes, masking agents, or synthetic scents.

Are Loo Cleaner Tabs fragrance-free?
Yes. Loo Cleaner Tabs are 100% fragrance-free. No added perfumes, no synthetic scents, no masking agents. Most mainstream toilet cleaners use heavy fragrances to mask the chemical smell of the cleaning ingredients. Koh skips that entirely. This makes Loo Cleaner Tabs a better choice for sensitive noses, allergy-prone households, and anyone who prefers clean-smelling-like-nothing.
✓ Nothing added to hide anything
No added perfumes. No masking agents. No synthetic scents. Nothing to irritate sensitive airways. If you're sensitive to toilet bowl cleaner smells, Loo Cleaner Tabs are designed for you.
Can I add a scent to the Loo Cleaner Tab?
Yes. Drop a couple of drops of your favourite essential oil directly into the toilet bowl along with the Loo Cleaner Tab. Popular choices are eucalyptus (fresh and clean), tea tree (antimicrobial feel), and lavender (calming). Two to three drops is plenty per clean. Any more won't make the scent stronger and risks leaving an oily residue on the bowl. Add the oil to the bowl only, never to the cistern tank.
✓ How to add a scent
2 to 3 drops of essential oil in the bowl along with the Loo Cleaner Tab. Eucalyptus, tea tree, or lavender are the popular picks. Swirl gently, let it soak, scrub, flush. That's the full routine.
Can I add essential oils to the cistern tank?
No. Never add essential oils to the cistern tank. Oils can build up on the rubber seals, flapper valve, and fill valve inside the cistern, causing them to degrade or warp over time. This leads to leaks, running toilets, and costly plumbing repairs. Add essential oils to the bowl only. If you use the cistern method for Loo Cleaner Tabs, keep oils out of it.
⚠ Never add essential oils to the cistern tank
Essential oils can degrade the rubber seals, flapper valve, and fill valve inside the cistern, leading to leaks and running toilets. Oils belong in the bowl only, alongside the tab.
