Does Bathroom & Shower Cleaner kill mould or bacteria?Updated a day ago

No. Bathroom & Shower Cleaner is a cleaner, not a disinfectant or registered anti-mould product. It breaks down and lifts away soap scum, body oils, bathroom grime, and surface mildew. It isn't tested against the antimicrobial or sporicidal standards that would support a "kills mould" or "kills bacteria" claim, and Koh does not make those claims. Regular cleaning physically removes microbes from hard surfaces to healthy levels, and good ventilation plus drying after use keeps mould from coming back. For embedded mould in grout or silicone, physical removal (re-grouting or re-siliconing) is usually the right answer.

For light surface mildew on tiles, glass, or enamel: ventilate the room first, wear gloves (and a mask if you're sensitive to spores), spray Bathroom & Shower Cleaner and let the foam sit for 1 to 2 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 embedded mould in grout or silicone, physical removal (re-grouting or re-siliconing) is usually the right answer.

Mould needs moisture, so removing the moisture removes the mould's food. 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 20 minutes after. Keep the shower tidy so air can flow. Wash cloths and bath mats regularly. Fix leaks and seal failures promptly. A weekly clean with Bathroom & Shower Cleaner keeps soap scum (mould's favourite food) off surfaces in the first place.
