Bathrooms are wet, warm, and humid—creating the perfect conditions for mould and mildew to grow. Black mould stains on grout, ceilings, and shower screens are unsightly, and their spores can cause respiratory irritation. Cleaning existing mould and taking preventative ventilation measures is essential to keep your bathroom hygienic.
How to Clean Existing Mould
For tiled walls and grout lines, mix one part white vinegar with one part water in a spray bottle. Spray the affected areas and let it sit for an hour. Scrub the grout lines with a stiff toothbrush, rinse with warm water, and wipe dry. For stubborn mould, make a baking soda and vinegar paste, apply to the grout, scrub, and rinse.
Ventilation: The Best Preventative
Mould cannot grow without moisture. Improving ventilation is key:
- Exhaust Fan: Always turn on the exhaust fan before showering, and leave it running for 15-20 minutes after you finish.
- Squeegee the Walls: Use a squeegee to pull water off shower walls and glass screens after every shower, reducing drying time by 90%.
- Keep it Dry: Leave the bathroom door or window open slightly after use to allow damp air to escape.
