How to Clean Mould Off Bathroom Walls: 1 Minute to a Fresh, Mould-Free Bathroom

Mould on bathroom walls is a common issue, thanks to the room’s persistent moisture and humidity. If you’ve spotted those telltale black, green, or brown spots, it’s important to address them quickly—not just for aesthetics, but for your health as well. Here’s a step-by-step approach to cleaning mould off your bathroom walls and ensuring it doesn’t return.

1. Prepare Your Space & Materials: Ensure good ventilation by opening windows or running an exhaust fan. Wear gloves, goggles, and a mask for safety. You’ll need household white vinegar, baking soda, a spray bottle, a sponge or soft brush, and clean towels.
2. Apply Vinegar Solution: Fill a spray bottle with undiluted white vinegar and spritz it directly onto the mouldy patches. Let it sit for at least an hour to penetrate the mould.
3. Scrub the Area: Use a sponge or soft-bristled brush to scrub the affected area gently. For stubborn spots, make a paste from baking soda and water, apply it to the mould, and scrub again.
4. Rinse & Dry: Wipe down the wall with a clean, damp cloth to remove residue. Dry the wall thoroughly with towels or a fan.
5. Discourage Future Mould: Use a bathroom exhaust fan or dehumidifier regularly, fix any water leaks, and wipe down wet walls after showers to stop mould before it starts.

As a designer, I always recommend integrating functional yet beautiful solutions to prevent recurring mould. Consider upgrading your ventilation system, selecting anti-mould paints, or even rethinking your bathroom layout to optimize airflow and reduce moisture retention. This approach not only enhances your bathroom’s appearance but also makes maintenance easier. For a smarter, healthier space, tools like a bathroom design tool can help reimagine the layout, ensuring both aesthetics and long-term functionality.

Tips 1:

After cleaning, consider repainting affected walls with a mould-resistant paint. This adds a layer of protection and gives your bathroom a fresh look.
