7 Natural Ways to Remove Mould & Mildew Without Harsh Chemicals
Mould and mildew can quickly become an unwanted guest in Australian homes, particularly during the cooler and wetter months. While traditional cleaners can be effective, many contain harsh chemicals that aren't ideal for families, pets, or the planet. Fortunately, there are safe, plant-based alternatives that can help you tackle mould naturally—without compromising on effectiveness.
In this guide, we explore seven natural methods to remove mould and mildew, and share our favourite eco-friendly products available from Eco Traders.
1. Tea Tree Oil Spray
Tea tree oil is a powerful natural antifungal and antibacterial essential oil. It's incredibly effective against mould and mildew and has a pleasant, clean scent.
How to use:
-
Mix 1 teaspoon of tea tree oil with 1 cup of water in a spray bottle.
-
Shake well and spray directly onto the mouldy area.
-
Leave for an hour before wiping clean.
Try This: Tri Nature Mould Cleaner 500ml – enriched with essential oils including tea tree.
2. White Vinegar Solution
White vinegar is acidic, making it ideal for killing mould spores. It can eliminate up to 80% of mould types.
How to use:
-
Spray undiluted white vinegar onto affected surfaces.
-
Let it sit for at least an hour, then scrub and rinse.
Eco Tip: Add a few drops of lemon or eucalyptus essential oil for a fresh, clean scent.
3. Baking Soda Paste
Baking soda is mildly abrasive and has natural deodorising and antifungal properties.
How to use:
-
Mix baking soda with a small amount of water to form a paste.
-
Apply to mouldy grout, tiles, or silicone.
-
Scrub with a brush and rinse.
Pair With: Simply Clean – No Mould Spray 500ml to finish the clean and prevent regrowth.
4. Hydrogen Peroxide (Food Grade)
Hydrogen peroxide is a non-toxic, natural bleaching agent that kills mould on contact.
How to use:
-
Spray 3% hydrogen peroxide onto mould.
-
Allow it to bubble for 10 minutes before scrubbing and rinsing.
Caution: Test on a small area first as it may slightly bleach fabrics or surfaces.
5. Eucalyptus Oil Cleaner
Known for its antifungal and germ-killing properties, eucalyptus oil is another Aussie favourite.
How to use:
-
Mix 2 teaspoons eucalyptus oil with 2 cups water.
-
Use a cloth or spray bottle to apply.
Try This: Koala Eco Multi-Purpose Kitchen Cleaner 500ml – formulated with eucalyptus and mandarin oils.
6. Clove Oil Treatment
Clove oil not only kills mould but helps prevent it from returning. It’s strong—so use sparingly.
How to use:
-
Mix 1/4 teaspoon clove oil with 1 litre of water.
-
Apply to the surface, leave overnight, and wipe off the next day.
Pro Tip: Avoid overusing clove oil—it’s potent and can stain lighter surfaces.
