Aqua, deionised water, is the solvent base that carries the other ingredients and rinses cleanly off surfaces. Ethanol is a solvent that cuts oils and helps the foam spread evenly. Sodium lauryl sulfate is a low-foam wetting surfactant. Cocamidopropyl betaine is a mild surfactant. Sodium xylene sulfonate is a hydrotrope that keeps the formula stable and evenly mixed. Sodium metasilicate pentahydrate is a builder that helps with grease. Trisodium dicarboxymethyl alaninate is a chelator that grips hard-water minerals. Polyacrylic acid sodium salt is an anti-redeposition agent that stops lifted soil settling back on the surface. Xanthan gum is the thickener. Phenoxyethanol is the preservative. Lipase is an enzyme that breaks down fats and body oils. Tocopheryl acetate is vitamin E, included as an antioxidant and a skin-friendly ingredient.</p><div style="background:#E6F1FB; border-radius:12px; padding:1.25rem; margin:1rem 0;"><p style="font-size:14px; font-weight:500; color:#0C447C; margin:0 0 12px;">&#x2713; All twelve, in INCI order</p><p style="font-size:13px; color:#185FA5; margin:0 0 8px; line-height:1.6;"><strong style="color:#0C447C;">Aqua (deionised water).</strong> Solvent base.

That is deliberately gentle compared with traditional bathroom cleaners, which are often either strongly acidic, such as vinegar-based descalers at pH 2 to 3, or strongly alkaline, such as ammonia-based products at pH 11 to 13. The mild pH is gentle enough for the product to be Dermatest tested and Eczema Association recognised, while still handling soap scum, body oils and mineral deposits. Shelf life is approximately 12 months from the date of manufacture when stored sealed, cool and out of direct sunlight. Do not freeze it or expose it to heat. It is made in Australia.</p><div style="display:grid; grid-template-columns:repeat(auto-fit, minmax(220px, 1fr)); gap:10px; margin:1rem 0;"><div style="background:#E6F1FB; border-radius:12px; padding:1.25rem; display:flex; flex-direction:column;"><p style="font-size:14px; font-weight:500; color:#0C447C; margin:0 0 10px;">&#x2713; pH around 8</p><p style="font-size:13px; color:#185FA5; margin:0 0 10px; line-height:1.6;">Mildly alkaline, just above neutral.

Is Bathroom & Shower Cleaner allergy, asthma and sensitive skin friendly?

Yes. Built for bathrooms, but works on sealed, non-porous surfaces: glass, furniture, bins, bikes, sports gear. Not food-grade, skip food prep. →

<article id="bsc-use-elsewhere" class="promo-article"><p><strong>TL;DR:</strong> Yes. <a href="https://uk.koh.com/products/bathroom-shower-cleaner" target="_blank" rel="noopener noreferrer"><strong>Bathroom &amp; Shower Cleaner</strong></a> is designed for bathrooms, tiles, glass, chrome and grout, but it also works on most sealed, non-porous surfaces that can take a foam-and-rinse clean. Good candidates: glass and windows, outdoor furniture, bins, outdoor tiles and paths, bikes, sports gear and non-porous toys. Always spot test first and rinse thoroughly. It is not food-grade, so skip food-prep surfaces and anything a child puts in their mouth.</p><div style="display:flex; align-items:center; gap:12px; margin:1.5rem 0;"><div style="flex:1; height:1px; background:#A8C7E9;"><br></div><span style="font-size:11px; color:#185FA5; font-weight:500; letter-spacing:0.05em; text-transform:uppercase;">Read on &#x2193;</span><div style="flex:1; height:1px; background:#A8C7E9;"><br></div></div><div style="display:grid; grid-template-columns:repeat(auto-fit, minmax(220px, 1fr)); gap:10px; margin:1rem 0;"><div style="margin:0;"><a href="https://uk.koh.com/products/bathroom-shower-cleaner" target="_blank" rel="noopener noreferrer"><img src="https://cdn.shopify.com/s/files/1/0120/2110/4699/files/6.Koh_Effective-ProblemsSolution_Bath-Shower_06a13495-42af-405e-9d5c-7a3b566a442f.jpg?width=400" alt="Koh Bathroom and Shower Cleaner on common problems" style="width:100%; height:auto; border-radius:12px;" class="fr-fil fr-dib"></a></div><div style="margin:0;"><a href="https://uk.koh.com/products/bathroom-shower-cleaner" target="_blank" rel="noopener noreferrer"><img src="https://cdn.shopify.com/s/files/1/0120/2110/4699/files/4.Koh_Effective_Before-After_Bath-Shower_2bd58cfe-4e55-45bc-9372-13c6b6a53906.jpg?width=400" alt="Koh Bathroom and Shower Cleaner before and after" style="width:100%; height:auto; border-radius:12px;" class="fr-fil fr-dib"></a></div></div><hr><div itemscope itemtype="https://schema.org/FAQPage"><div itemprop="mainEntity" itemscope itemtype="https://schema.org/Question" id="around-the-house"><h2 itemprop="name" style="position:absolute; left:-10000px; width:1px; height:1px; overflow:hidden;" id="is-it-only-for-use-in-the-bathroom-and-shower-or-can-i-use-it-elsewhere">Is it only for use in the bathroom and shower, or can I use it elsewhere?</h2><div itemprop="acceptedAnswer" itemscope itemtype="https://schema.org/Answer"><p itemprop="text" style="display:none;">Bathroom and Shower Cleaner is good on glass and windows, outdoor furniture in plastic, powder-coated metal or glass, outdoor tiles and paths, and bins. The foam clings, lifts dirt and rinses clean with water. For windows, a quick spray, wipe and buff with a clean microfibre leaves a streak-free finish. For bins, a deep foam-and-rinse cuts grime and neutralises odour inside and out. Sealed surfaces only, and always rinse thoroughly.</p><div style="background:#E6F1FB; border-radius:12px; padding:1.25rem; margin:1rem 0; display:flex; flex-direction:column;"><p style="font-size:14px; font-weight:500; color:#0C447C; margin:0 0 10px;">&#x2713; Good around the house</p><p style="font-size:13px; color:#185FA5; margin:0 0 10px; line-height:1.6;">Glass and windows, outdoor furniture, outdoor tiles, paths and bins.

Is it only for use in the bathroom and shower or can I use it elsewhere?

No. It's a cleaner, not a disinfectant or mould killer, with no biocidal authorisation in Great Britain. Cleaning removes what mould feeds on. →

Is Bathroom & Shower Cleaner anti-microbial or anti-mould?

No, by design: no perfumes, masking scents or synthetic fragrance. Add 2-3 drops of essential oil to the foamer if desired. Never citrus oils. →

The absence of fragrance is part of what makes it Sensitive Choice approved by the National Asthma Council Australia.

Add two to three drops of a mild essential oil, such as eucalyptus or lavender, to your Foaming Spray Bottle after you have mixed the foam, then swirl gently to combine. Keep it minimal, because two to three 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, which damage the foamer mechanism over time.</p><div style="background:#E6F1FB; border-radius:12px; padding:1.25rem; margin:1rem 0;"><p style="font-size:14px; font-weight:500; color:#0C447C; margin:0 0 12px;">&#x2713; How to add a light scent</p><div style="display:flex; align-items:flex-start; gap:12px; margin-bottom:10px;"><span style="display:inline-flex; align-items:center; justify-content:center; width:24px; height:24px; border-radius:50%; background:#305AD0; color:#ffffff; font-size:11px; font-weight:500; flex-shrink:0;">1</span><p style="font-size:13px; color:#185FA5; margin:2px 0 0; line-height:1.6;"><strong style="color:#0C447C;">Fill the foamer.</strong> Mix Bathroom &amp; Shower Cleaner in your <a href="https://uk.koh.com/products/foaming-spray-bottle" target="_blank" rel="noopener noreferrer" style="color:#0C447C;"><strong>Foaming Spray Bottle</strong></a> as normal.</p></div><div style="display:flex; align-items:flex-start; gap:12px; margin-bottom:10px;"><span style="display:inline-flex; align-items:center; justify-content:center; width:24px; height:24px; border-radius:50%; background:#305AD0; color:#ffffff; font-size:11px; font-weight:500; flex-shrink:0;">2</span><p style="font-size:13px; color:#185FA5; margin:2px 0 0; line-height:1.6;"><strong style="color:#0C447C;">Add two to three drops of essential oil.</strong> <a href="https://uk.koh.com/products/essential-oil-eucalyptus" target="_blank" rel="noopener noreferrer" style="color:#0C447C;"><strong>Eucalyptus</strong></a> or lavender are safe choices.

Does Bathroom & Shower Cleaner have a fragrance?

Most likely, yes, though Koh hasn't tested it against branded coatings. pH 8 and non-abrasive, matching typical care guidance. Spot test first. →

Can I use it to clean EnduroShield or similar coated shower screens?

Bathroom and Shower Cleaner is formulated without the chemistries most commonly flagged for animals. There is no added fragrance, no chlorine bleach, no strong acids and no aerosol propellants, and the formula is mildly alkaline at pH 8 rather than caustic or strongly acidic. It is Sensitive Choice approved by the National Asthma Council Australia, Dermatest tested and recognised by the Eczema Association of Australasia, all of which screen against ingredients commonly linked to respiratory and skin sensitivity. Every animal has a unique biological makeup, so Koh cannot guarantee compatibility with every pet. If your pet has known chemical sensitivities, or a habit of licking floors and tiles, check with your vet before introducing a new cleaner to the home.</p><div style="background:#E6F1FB; border-radius:12px; padding:1.25rem; margin:1rem 0; display:flex; flex-direction:column;"><p style="font-size:14px; font-weight:500; color:#0C447C; margin:0 0 10px;">&#x2713; Considered for pet households</p><p style="font-size:13px; color:#185FA5; margin:0 0 10px; line-height:1.6;">Formulated without the ingredients most commonly flagged for animals: no added fragrance, no chlorine bleach, no strong acids, no aerosol propellants.

They walk on floors and bath bases, brush against skirtings and basins, and groom themselves by licking. Residue from cleaning products therefore matters more for them than for us. Bathroom and Shower Cleaner is a rinse-off product, it leaves no perfumed residue behind, and its independent approvals screen against ingredients commonly flagged for respiratory and skin sensitivity. That makes it a more considered option than a conventional bleach or acid-based bathroom cleaner in homes with dogs, cats, rabbits or birds. It is still a bathroom cleaner and not a pet-care product, so it should never be used on bowls, chew toys or directly on an animal.</p><div style="background:#E6F1FB; border-radius:12px; padding:1.25rem; margin:1rem 0; display:flex; flex-direction:column;"><p style="font-size:14px; font-weight:500; color:#0C447C; margin:0 0 10px;">&#x2713; Why it works in pet homes</p><p style="font-size:13px; color:#185FA5; margin:0 0 10px; line-height:1.6;">Pets live closer to cleaned surfaces than we do, and they groom themselves by licking.

Is Bathroom & Shower Cleaner safe to use around pets?

Yes, when used as directed. No chlorine, phosphates or quats, readily biodegradable. It's a cleaner not a disinfectant, so septic bacteria are safe. →

Cleaners built around chlorine bleach, strong disinfectants or antibacterial actives kill those beneficial bacteria along with everything else. Once the colony crashes, waste stops breaking down, solids build up and the system backs up or fails. Bathroom and Shower Cleaner is a cleaner rather than a disinfectant. It is not a disinfectant, sanitiser or mould killer, it holds no biocidal product authorisation in Great Britain, and Koh makes no germ-kill claim for it.

It is not tested against antimicrobial standards and it holds no biocidal product authorisation in Great Britain, so Koh makes no germ-kill claim for it. That is the trade-off, and in a septic home it is the point: a product that killed bacteria on your tiles would kill them in your tank too.</p><div style="display:flex; flex-wrap:wrap; gap:6px; margin-top:auto;"><span style="font-size:12px; font-weight:500; color:#633806; background:#FFF36E; border-radius:20px; padding:3px 10px;">Not a disinfectant</span> <span style="font-size:12px; font-weight:500; color:#633806; background:#FFF36E; border-radius:20px; padding:3px 10px;">No germ-kill claim</span> <span style="font-size:12px; font-weight:500; color:#633806; background:#FFF36E; border-radius:20px; padding:3px 10px;">Not biocide-authorised in GB</span></div></div></div></div><hr><div itemprop="mainEntity" itemscope itemtype="https://schema.org/Question" id="rural-caravans"><h2 itemprop="name" id="is-it-suitable-for-rural-homes-caravans-and-boats">Is it suitable for rural homes, caravans and boats?</h2><div itemprop="acceptedAnswer" itemscope itemtype="https://schema.org/Answer"><p itemprop="text" style="display:none;">Yes. Bathroom and Shower Cleaner suits any home or vehicle running a septic tank, a package sewage treatment plant, a holding tank or a greywater system. That covers rural and off-mains properties, caravans, camper vans, motorhomes, boats and off-grid setups. The same properties that make it septic compatible make it greywater compatible: readily biodegradable, no chlorine, no phosphates and low sodium, so what rinses away is not carrying a load of persistent chemistry with it.

Bathroom and Shower Cleaner is built for depth. It is a twelve-ingredient enzyme-powered foam, including lipase, surfactants and builders, that clings to vertical surfaces and breaks down soap scum, body oils and hard-water build-up.

Universal Cleaner is good for quick bathroom touch-ups: wiping basins, worktops, mirrors and toilet exteriors without rinsing. Bathroom and Shower Cleaner is the right tool for the shower screen, tiles, grout, bath and anywhere soap scum or body oils build up. The foam clings to vertical surfaces, the enzymes work on organic grime, and the rinse carries everything away. Many people use both: Universal Cleaner for midweek touch-ups, Bathroom and Shower Cleaner for the weekly deep clean.</p><div style="display:grid; grid-template-columns:repeat(auto-fit, minmax(220px, 1fr)); gap:10px; margin:1rem 0;"><div style="background:#E1F5EE; border-radius:12px; padding:1.25rem; display:flex; flex-direction:column;"><p style="font-size:14px; font-weight:500; color:#085041; margin:0 0 10px;">&#x2713; Reach for Universal Cleaner when</p><p style="font-size:13px; color:#0F6E56; margin:0 0 10px; line-height:1.6;">You want a quick wipe-down of basins, worktops, mirrors, toilet seats and exteriors.

Universal Cleaner vs. Bathroom & Shower Cleaner: What’s the Difference?

Yes. GECA certified since June 2026, Australia's ecolabel. Twelve biodegradable ingredients, no chlorine or phosphates, in a low-plastic refill. →

What makes it "eco friendly"?

Yes, above the waterline: seat, lid, rim, bowl walls, exterior. Below the waterline, use Loo Cleaner Tabs. It cleans, not disinfects. →

<article id="bsc-toilet-bowl" class="promo-article"><p><strong>TL;DR:</strong> Yes, above the waterline. <a href="https://uk.koh.com/products/bathroom-shower-cleaner" target="_blank" rel="noopener noreferrer"><strong>Bathroom &amp; Shower Cleaner</strong></a> handles the seat, lid, rim, under-rim, bowl walls, base and exterior. Below the waterline the foam simply dilutes in the water and stops working, so use <a href="https://uk.koh.com/products/loo-cleaner-tablets" target="_blank" rel="noopener noreferrer"><strong>Loo Cleaner Tabs</strong></a> there instead. Scrub with the <a href="https://uk.koh.com/products/loo-blade-white" target="_blank" rel="noopener noreferrer"><strong>Loo Blade</strong></a>, flush, done. One thing to be clear about: this is a cleaner, not a disinfectant or sanitiser, and it holds no biocidal product authorisation in Great Britain.</p><div style="display:flex; align-items:center; gap:12px; margin:1.5rem 0;"><div style="flex:1; height:1px; background:#A8C7E9;"><br></div><span style="font-size:11px; color:#185FA5; font-weight:500; letter-spacing:0.05em; text-transform:uppercase;">Read on &#x2193;</span><div style="flex:1; height:1px; background:#A8C7E9;"><br></div></div><div style="display:grid; grid-template-columns:repeat(auto-fit, minmax(220px, 1fr)); gap:10px; margin:1rem 0;"><div style="margin:0;"><a href="https://uk.koh.com/products/bathroom-shower-cleaner" target="_blank" rel="noopener noreferrer"><img src="https://cdn.shopify.com/s/files/1/0120/2110/4699/files/8.Koh_Effective_Bath-Shower_affcb0b0-439e-46b1-9a01-4ed7a8d69dca.jpg?width=400" alt="Koh Bathroom and Shower Cleaner foam" style="width:100%; height:auto; border-radius:12px;" class="fr-fil fr-dib"></a></div><div style="margin:0;"><a href="https://uk.koh.com/products/loo-cleaner-tablets" target="_blank" rel="noopener noreferrer"><img src="https://cdn.shopify.com/s/files/1/0120/2110/4699/files/Koh_Effective-Loo_07576a20-b88d-4cea-884c-d6b74052171b.jpg?width=400" alt="Koh Loo Cleaner Tabs in a toilet bowl" style="width:100%; height:auto; border-radius:12px;" class="fr-fil fr-dib"></a></div></div><hr><div itemscope itemtype="https://schema.org/FAQPage"><div itemprop="mainEntity" itemscope itemtype="https://schema.org/Question" id="above-waterline"><h2 itemprop="name" style="position:absolute; left:-10000px; width:1px; height:1px; overflow:hidden;" id="can-i-use-bathroom--shower-cleaner-to-clean-the-bowl-of-the-toilet">Can I use Bathroom &amp; Shower Cleaner to clean the bowl of the toilet?</h2><div itemprop="acceptedAnswer" itemscope itemtype="https://schema.org/Answer"><p itemprop="text" style="display:none;">Yes, above the waterline.

It ships in a 1.8L bag-in-box: a cardboard outer with a flexible bladder inside. Pour it directly into the Foaming Spray Bottle as it comes from the box. Adding water dilutes the formula and reduces cleaning performance. Do not mix it with other products either, because combining cleaners can deactivate ingredients or cause unwanted reactions.</p><div style="background:#FAEEDA; border-radius:12px; padding:1.25rem; margin:1rem 0; display:flex; flex-direction:column;"><p style="font-size:14px; font-weight:500; color:#633806; margin:0 0 10px;">&#x26A0; Ready to use, do not dilute</p><p style="font-size:13px; color:#854F0B; margin:0 0 10px; line-height:1.6;">Pour straight into the Foaming Spray Bottle.

How much Bathroom & Shower foam should I use?

Yes, but as a last resort. Start with the Ultra Pro Mitt, step up to Scrubby Pads, then the Diamond Sponge. Never on plastics, chrome or coatings. →

Diamond Sponges pair well with Bathroom and Shower Cleaner for the toughest bathroom build-up: hardened soap scum, limescale rings, neglected grout lines and mineral deposits on glazed tiles.

The Ultra Pro Bathroom Mitt handles the large majority of bathroom cleaning: general soap scum, body oils and day-to-day grime. For stuck-on or thicker build-up, step up to Scrubby Pads, which are more abrasive but still safe for most sealed bathroom surfaces. Only bring out a Diamond Sponge when the first two have not shifted it.

Can I use Bathroom & Shower Cleaner with a Diamond Sponge?

Generally yes on sealed stone. pH 8, non-abrasive, gentler than acidic etching cleaners. Not for unsealed stone or worn sealants. Spot test first. →

Applying to the cloth rather than the surface keeps contact time short and stops product pooling in seams or running into unsealed edges.
