Let’s face it: bathrooms are ground zero for mould and mildew. That slimy black gunk in your grout? The pink film on your shower curtain? It’s not just ugly—it’s a health hazard. As a Brisbane homeowner who’s battled everything from post-storm humidity to sneaky leaks under sinks, I’ve learned that preventing mildew buildup isn’t about scrubbing harder. It’s about working smarter. Here’s your no-nonsense guide to keeping your bathroom fresh, safe, and mould-free.
Why Bathrooms Are Mould Magnets
- Moisture overload: Showers, sinks, and leaks keep surfaces damp.
- Poor ventilation: Trapped humidity feeds mould spores.
- Organic buffet: Soap scum, skin cells, and dust give mould something to eat .
Daily Habits to Crush Mould & Mildew
1. Master the Post-Shower Shake-Down
- Squeegee like a pro: Wipe down shower walls and doors after every use. This simple step removes 70% of moisture that mould needs to grow.
- Towel tactics: Hang wet towels outside the bathroom. Damp towels draped over racks are mildew’s best friend.
- Airflow is king: Leave the shower curtain open, crack a window, or run the exhaust fan for 30+ minutes post-shower.
Pro Tip: No exhaust fan? Place a small desktop fan near the door to circulate air.
2. Outsmart Hidden Moisture Traps
- Elevate shower products: Use a wire rack or suction caddies to keep shampoo bottles off ledges. Stagnant water under bottles breeds mould.
- Dry your loofah: Hang it outside the shower. A damp loofah can grow mould in 48 hours.
- Check the “Forgotten Zones”: Wipe sink overflow holes, toothbrush holders, and soap dishes weekly – these spots trap grime.

3. Attack Grout Like a Pro
4. Shower Curtain Rescue Mission
Grout is mould’s favorite playground. Here’s how to reclaim it:
- Mix a DIY grout cleaner: Combine 1 part hydrogen peroxide + 1 part baking soda into a paste. Scrub with an old toothbrush.
- Rinse with vinegar: Spray white vinegar to disinfect and neutralize odors.
- Seal annually: Apply a grout sealer to block moisture – this cuts future scrubbing by 80%.
Warning: Avoid bleach on coloured grout – it can yellow over time.
- Monthly soak: Strip the curtain and liner, toss them in the washing machine with ½ cup vinegar + ½ cup baking soda. Air dry completely.
- Spot treatment: Spray stubborn mildew with tea tree oil (1 tsp oil + 1 cup water). Let sit for 1 hour before scrubbing.
Budget Hack: Replace plastic liners every 6 months. Dollar store options work fine!

5. Upgrade Your Bathroom’s “Lungs”
- Exhaust fan tune-up: Calculate your fan’s CFM (cubic feet/minute). It should be 1.1x your bathroom’s square footage. Too weak? Upgrade to a humidity-sensing model.
- Dehumidifier magic: Run a compact dehumidifier during humid months. Aim for 40-50% humidity – mould can’t survive below 60%.
6. Leak-Proof Your Space
- Weekly checks: Look under sinks, around toilets, and behind cabinets. A leaking pipe can fuel mould growth in just 72 hours .
- Fix cracks fast: Re-caulk peeling sealant around tubs and sinks. Use mould-resistant silicone caulk for lasting protection.
Pro Tip: Place a moisture absorber (like DampRid) under sinks to catch hidden leaks.
Common Mistakes That Feed Mould
7. The “Cleaner = Better” Myth
- Avoid bleach overload: Bleach only kills surface mould – it won’t stop roots in porous surfaces like drywall. Opt for vinegar or hydrogen peroxide instead.
- Steam mop misuse: Steam cleansers push moisture into grout. Use them sparingly and dry floors immediately.
8. Ignoring the Invisible
- Test your walls: Suspect hidden mould? Tape a plastic sheet to the wall for 48 hours. Condensation underneath means moisture is trapped.
- Inspect exhaust ducts: Dust-clogged vents recirculate humid air. Vacuum ducts quarterly.
When to Call Home Cleaning Services
While DIY works for small jobs, home cleaning services are lifesavers for:
- Persistent mould: If it returns within weeks, pros use industrial-grade antimicrobial treatments.
- Post-flood cleanup: Water damage behind walls requires professional drying to prevent toxic mould.
- Grout restoration: Professionals can regrout and seal tiles for a 5+ year mould-free guarantee.
Brisbane Hack: Many local services offer mould inspections for under $150 – worth it for peace of mind!
Final Checklist for a Mould-Free Bathroom
- Daily: Squeegee shower, run fan, hang towels.
- Weekly: Scrub grout, wash curtains, check leaks.
- Monthly: Clean exhaust vents, refresh caulk.
- Yearly: Reseal grout, replace shower liners.
