How to Remove Mould from Melbourne Bathrooms: Prevention and Treatment

Melbourne's humid climate makes bathrooms a prime target for mould growth. Left untreated, mould can damage surfaces, compromise indoor air quality, and affect your family's health. Here's how to tackle it effectively and stop it coming back.

Why Melbourne Bathrooms Are Prone to Mould

Melbourne's average humidity sits around 60 to 70% throughout the year. Combined with hot showers, poor ventilation in older buildings, and limited natural light in many bathrooms, it creates perfect conditions for mould to thrive.

This is especially common in Melbourne's inner suburbs like Fitzroy, Carlton, and Collingwood where Victorian era terrace houses often have bathrooms with minimal ventilation and no windows.

Understanding Mould Types

Not all mould is the same. The type you're dealing with affects how you should treat it.

• Black mould on grout is the most common. It feeds on soap residue and body oils trapped in porous grout
• Pink mould (actually bacteria) appears on shower curtains, grout, and around drains
• White fuzzy mould often indicates a moisture problem behind walls that needs investigation
• Dark patches on ceilings suggest a ventilation issue or possible water leak above

Effective DIY Mould Removal

• Mix 1 part white vinegar to 1 part water in a spray bottle
• Spray affected areas generously and leave for 30 minutes minimum
• Scrub with a stiff brush, paying special attention to grout lines
• Rinse thoroughly with warm water and dry the surface completely
• For stubborn spots, make a paste of baking soda and water, apply to the mould, spray with vinegar, and scrub after fizzing

When Professional Help Is Needed

If mould covers more than 1 square metre, keeps returning within weeks of cleaning, or you can smell a musty odour you can't locate, you need professional treatment. Our deep cleaning service includes industrial grade mould treatment.

For persistent grout mould, professional tile and grout cleaning restores surfaces to like new condition and applies protective sealing.

Prevention Strategies That Work

• Run exhaust fans during showers and for at least 15 minutes afterwards
• Keep bathroom doors open when not in use to allow air circulation
• Squeegee shower screens and tiles after each use
• Professional caulking and sealing prevents moisture from getting behind tiles where hidden mould grows
• Ensure adequate waterproofing in all wet areas
• Consider installing a timer on your exhaust fan so it runs automatically
