Wear a mask, gloves and goggles whatever the size, and keep the window open during and after the clean." }, { "question": "Should I use bleach on bathroom mould?", "answer": "No. Gov.uk says mould and mildew products should be used in preference to bleach, for health and safety reasons, and UniBond says bleach can damage silicone sealant. Follow the safety instructions on the product label, and let the surface dry completely afterwards." }, { "question": "Why does mould keep coming back on the sealant?", "answer": "Usually because it has grown into the silicone. UniBond says that when mould has set too deeply into sealant, it needs to be removed and replaced rather than cleaned. Strip the old bead, wipe the joint with white spirit on a cloth, let it dry, then apply new anti-mould sealant." }, { "question": "Who fixes a broken extractor fan in a rented bathroom?", "answer": "The landlord, if they installed it.

Gov.uk says damp and mould put children, older people and anyone with asthma or another lung condition most at risk. Cleaning the tiles removes the mould you can see; it is not a health measure.
