Universal Cleaner vs. Bathroom & Shower Cleaner: What’s the Difference?Updated 10 days ago
TL;DR: Universal Cleaner is a spray-and-wipe, no-rinse formula for everyday cleaning across a wide range of surfaces, including the bathroom. Bathroom & Shower Cleaner is an enzyme-powered foam designed to break down soap scum, body oils and bathroom build-up, and it needs dwell time and a rinse. They are partners, not replacements: Universal Cleaner for the quick clean, Bathroom & Shower Cleaner for the deeper scrub.
Universal Cleaner vs Bathroom & Shower Cleaner: what's the difference?
✓ Universal Cleaner · built for breadth
A two-ingredient alkaline formula, potassium hydroxide and water, that handles grease, grime and light soiling across a wide range of surfaces including bathrooms, kitchens, floors and glass. Spray, wipe, no rinse. Pairs with the Atomiser Spray Bottle.
✓ Bathroom & Shower Cleaner · built for depth
A twelve-ingredient enzyme-powered foam that clings to vertical surfaces and breaks down soap scum, body oils and hard-water build-up. Needs dwell time and a water rinse. Pairs with the Foaming Spray Bottle.
Which one should I use in the bathroom?
✓ Reach for Universal Cleaner when
You want a quick wipe-down of basins, worktops, mirrors, toilet seats and exteriors. No rinse needed, streak-free finish, ideal for midweek touch-ups between deeper cleans.
✓ Reach for Bathroom & Shower Cleaner when
Shower screens with soap scum. Tiles and grout with hard-water build-up. Bath rings. Anywhere that needs the foam-to-cling, dwell and rinse method. This is the weekly deep clean.
What do they have in common, and where do they differ on certifications?
✓ Shared by both
Both are GECA certified, GECA being Australia's only multi-sector ecolabel: Universal Cleaner since April 2016, Bathroom & Shower Cleaner since June 2026. Both are also Sensitive Choice approved by the National Asthma Council Australia, recognised by the Eczema Association of Australasia, fragrance-free, septic safe and made in Australia, in bag-in-box packaging that uses significantly less plastic than a traditional rigid bottle.
✓ Universal Cleaner only
Universal Cleaner additionally holds Allergy UK approval, which Bathroom & Shower Cleaner does not. It is also Koh's longest-running GECA certification, held continuously since April 2016.
✓ Bathroom & Shower Cleaner only
Bathroom & Shower Cleaner additionally holds Dermatest testing for skin compatibility, which Universal Cleaner does not. It is not Allergy UK accredited.
⚠ Neither one disinfects
Neither product is a disinfectant, sanitiser or mould killer, and neither holds a biocidal product authorisation in Great Britain. Both clean by removing soil rather than by killing anything. If you need a genuine kill step, use a separate product authorised in Great Britain for that use.
