Is Bathroom & Shower Cleaner fragrance-free?Updated 13 days ago

Yes. Bathroom & Shower Cleaner contains no added perfumes, no masking scents, and no synthetic fragrance ingredients. The absence of fragrance is part of what makes it Sensitive Choice approved by the National Asthma Council Australia. You may notice a very mild, clean scent from the ingredients themselves (ethanol, for example), but nothing perfumed. It rinses away with water leaving no lingering smell.

Yes. Add 2 to 3 drops of a mild essential oil (lavender or eucalyptus work well) to your Foaming Spray Bottle after you mix the foam. Swirl gently to combine. Keep it minimal: 2 to 3 drops is enough for a subtle scent without affecting the formula or the foamer mechanism. More than that risks clogging the nozzle or leaving oily residue on surfaces. If anyone in your home is scent-sensitive, skip this step entirely. Never use citrus oils (lemon, orange, bergamot, lime, grapefruit), they damage the foamer mechanism over time.

Citrus oils (lemon, orange, bergamot, lime, grapefruit) contain solvents (d-limonene and other terpenes) that swell and degrade the plastic and rubber seals inside the Foaming Spray Bottle mechanism. Over time this causes sluggish spray, sticking triggers, leaking seals, and eventually mechanical failure. Lavender and eucalyptus are much gentler on the plastics. If you want a citrus scent in the bathroom, use it in a diffuser instead, not in the foamer.

Flush the Foaming Spray Bottle with warm water. Empty it, refill with clean warm water, and spray through the head 10 to 15 times to clear any oil residue or product build-up from the mechanism. Repeat if needed. If the sluggish spray persists after a good flush, the foamer mechanism may be degraded beyond recovery (most often from citrus oil use). A replacement Foaming Spray Bottle is available on the Koh site.
