The most effective way to get rid of mould in your laundry is to eliminate moisture, improve ventilation and apply professional antimicrobial treatment.
Laundries are one of the most mould-prone areas in any home. The constant exposure to water, warmth and limited airflow creates the perfect breeding ground for mould spores to settle and multiply.
Understanding how to get rid of mould in your laundry requires more than just surface cleaning. Long-term protection means addressing the root cause and preventing regrowth with proven strategies.
Why Mould Thrives in Laundries
Mould needs three things to grow: moisture, warmth and organic material. Your laundry provides all three in abundance, especially if you’re drying clothes indoors or running appliances without proper ventilation.
Common moisture sources in laundries include washing machines, dryers, wet clothing and steam from hot water. When these combine with poor airflow and porous surfaces like grout, plaster or painted walls, mould can establish itself within 24 to 48 hours.
- Washing machines with door seals that trap moisture
- Dryers venting moisture indoors instead of outside
- Damp towels and clothes left in baskets or on floors
- Leaking taps, pipes or appliance hoses
- Inadequate ventilation from windows, vents or exhaust fans
According to NSW Health, prolonged exposure to indoor mould can trigger respiratory issues, allergic reactions and asthma symptoms. Addressing mould growth early protects both your property and your health.
How to Get Rid of Mould in Your Laundry: Immediate Steps
If you’ve noticed visible mould in your laundry, acting quickly can prevent it from spreading to other areas. Start by identifying all affected surfaces, including walls, ceilings, grout, silicone seals and behind appliances.
Before attempting any cleaning, ensure the area is well-ventilated. Open windows, turn on exhaust fans and consider using a portable fan to circulate air.
- Wear gloves, a mask and protective eyewear to avoid direct contact with mould spores
- Remove and wash any affected fabrics in hot water (minimum 60°C)
- Wipe down hard surfaces with a damp cloth to capture spores rather than spreading them
- Dry all surfaces thoroughly using towels or fans
- Dispose of cleaning materials in sealed bags
Important: DIY cleaning only removes surface mould you can see. It doesn’t kill the mould roots embedded in porous materials like grout, plaster and painted walls, which is why mould returns so quickly.
Many homeowners in Newcastle and across the Central Coast find that mould returns within weeks unless the moisture source is resolved and professional treatment is applied.
DIY Methods vs Professional Mould Treatment
Many people attempt DIY solutions when they first discover mould. While these methods might make the surface look cleaner temporarily, they fail to address the underlying mould colony.
Why DIY mould removal fails:
- DIY products cannot penetrate porous surfaces where mould roots establish and spread
- Surface treatments provide no residual protection, allowing mould to regrow within days or weeks
- Store-bought solutions don’t address the moisture conditions that caused the mould in the first place
| Method | Effectiveness | Longevity | Safety |
|---|---|---|---|
| Bleach | Removes surface stains only | Days to weeks | Toxic fumes, damages surfaces |
| Vinegar | Limited surface impact | Days to weeks | Safe but ineffective on porous materials |
| Commercial sprays | Variable, often superficial | Weeks | May contain harsh chemicals |
| Professional antimicrobial treatment | Kills mould at the source | 12+ months with guarantee | Non-hazardous, non-corrosive, environmentally friendly |
Bleach might lighten mould stains temporarily, but it doesn’t penetrate porous surfaces where mould roots establish. Vinegar is similarly ineffective for anything beyond surface-level cosmetic improvement.
These temporary measures offer no lasting protection. Mould returns as soon as conditions allow because the underlying colony was never eliminated.
Professional treatment takes a different approach. Rather than masking the problem, professional Mould Removal uses an Australian-made, non-hazardous, non-corrosive and environmentally friendly antimicrobial solution that penetrates porous surfaces to eliminate mould at the source and prevent regrowth.
Mould and Hygiene Solutions backs this approach with an unconditional 12-month mould-free guarantee. You won’t waste time and money on repeated DIY attempts that only provide short-term cosmetic fixes.
Long-Term Prevention: How to Get Rid of Mould in Your Laundry for Good
Effective mould control in your laundry depends on managing moisture and maintaining consistent airflow. Even after professional treatment, these habits help maintain a mould-free environment.
Control Moisture Sources
- Ensure your dryer is vented to the outside, not into the laundry or roof cavity
- Check washing machine hoses and seals regularly for leaks or wear
- Leave the washing machine door and detergent drawer open after each use to allow drying
- Avoid leaving wet clothes in the machine or laundry basket for extended periods
- Fix dripping taps and leaking pipes immediately
Improve Ventilation
- Install or upgrade an exhaust fan rated for the size of your laundry
- Open windows during and after washing or drying to release humidity
- Use a dehumidifier in enclosed or poorly ventilated laundries
- Keep internal doors open when running appliances to allow airflow
- Avoid drying clothes indoors unless using a vented or condenser dryer
Maintain Surfaces
- Seal grout and porous surfaces to reduce moisture absorption
- Repaint walls with mould-resistant paint if needed
- Replace damaged silicone seals around sinks and benchtops
- Clean and dry surfaces regularly to prevent organic buildup
Professional Mould Prevention services can assess your laundry layout and recommend tailored solutions, from ventilation upgrades to protective coatings that reduce future risk. These measures work best when applied after professional mould elimination, not as a substitute for it.
When to Call a Professional
Some mould situations are best handled by trained specialists. If you’re dealing with recurring mould, large affected areas or mould behind walls or under flooring, professional Mould Remediation is the safest and most effective option.
- Mould covering more than one square metre
- Mould returning within weeks of cleaning
- Musty odours that persist even after cleaning
- Visible mould on walls, ceilings or behind appliances
- Health symptoms worsening when spending time in the laundry
A professional Mould Inspection can identify hidden moisture sources, assess the extent of contamination and provide a clear remediation plan. In many cases, what appears as a small patch of mould is just the visible portion of a larger problem within wall cavities or subfloor areas.
Mould and Hygiene Solutions uses thermal imaging and moisture meters to detect issues that aren’t visible to the naked eye. This ensures treatment targets the entire problem, not just the surface symptoms that DIY methods address.
Protect Your Home with a Free Mould Inspection
Understanding how to get rid of mould in your laundry starts with knowing the full extent of the issue. Surface cleaning with bleach, vinegar or commercial sprays might hide the problem temporarily, but without addressing moisture sources and applying professional antimicrobial treatment, mould will return.
Mould and Hygiene Solutions offers free inspections across Newcastle, the Central Coast and the Hunter Valley. Their team identifies the root cause, recommends tailored solutions and provides treatment backed by a 12-month mould-free guarantee.
If mould returns within 12 months of treatment, they return at no charge to resolve the issue. That’s the confidence that comes with using proven, professional-grade antimicrobial solutions instead of temporary DIY fixes that only treat surface mould.
