Is Bathroom & Shower Cleaner anti-microbial or anti-mould?Updated 8 days ago

No. Bathroom and Shower Cleaner is a cleaner, not a disinfectant, sanitiser or mould killer. It is not tested against the antimicrobial or sporicidal standards that would support a kills mould or kills bacteria claim, and it holds no biocidal product authorisation in Great Britain, so Koh makes no antimicrobial, disinfecting or mould-killing claim for it. What it does is break down and lift away soap scum, body oils, mineral film and bathroom grime, and it can lift light surface mildew from hard non-porous surfaces when you scrub and rinse. Removing that soil matters because soap scum and body oils are what mould feeds on. Where a genuine kill step is needed, use a product authorised in Great Britain for that use.

Mould does not grow on a clean, dry, hard surface for the fun of it. It grows in the film of soap scum, body oils and skin cells that builds up on tiles, glass and seals, and it needs moisture to do so. Cleaning removes that soil, so it takes away the food source, and drying afterwards takes away the moisture. That is why a weekly clean plus a squeegee after showers keeps a bathroom clear far more reliably than an occasional chemical blitz. Cleaning also physically removes microbes from the surface rather than killing them in place.

For light surface mildew on tiles, glass or enamel: ventilate the room first, wear gloves and a mask if you are sensitive to spores, spray Bathroom and Shower Cleaner and let the foam sit for one to two minutes, then scrub with a soft brush or cloth and rinse thoroughly. Dry the surface afterwards. Mildew lifts with mechanical action, not dwell time alone. For mould that is embedded in grout or silicone, physical removal by re-grouting or re-siliconing is usually the right answer, because no cleaner reaches roots inside a porous seal.

Mould needs moisture, so removing the moisture is the most effective thing you can do. Squeegee glass and tiles after every shower with the Bathroom Squeegee. Dry silicone seals and ledges. Run the extractor fan or open a window during showers and for twenty minutes after. Keep the shower uncluttered so air can flow. Wash cloths and bath mats regularly. Fix leaks and failed seals promptly. A weekly clean with Bathroom and Shower Cleaner keeps soap scum off surfaces in the first place, which removes what mould feeds on.
