Nana's anti-mould solution is made with care in the Northern Rivers using traditional wisdom and the best of Australian botanicals.
This isn’t just another cleaning spray. It’s a return to the simple, effective ways Nana used to keep homes clean and healthy — updated for modern Australian humidity.
Vinegar — The Trusted Foundation
We start with high-strength cleaning vinegar, the same pantry staple Nana relied on for generations. When you add water at home, it creates a gentle ~5% acetic acid solution. This natural acidity breaks down the mineral deposits mould loves to grow on and creates an environment most mould species can’t tolerate.
Clove and Tea Tree — The Heavy Hitters
These two powerful essential oils bring the real antifungal muscle.
| Clove Oil (high in eugenol) punches holes in mould cell walls and stops spores from germinating. |  |
 |
Tea Tree Oil (rich in terpinen-4-ol) interferes with how mould breathes and multiplies. |
Together, vinegar, clove and tea tree deliver reliable, natural power that’s been trusted for decades.
Our Nature-based Supporting Cast
While vinegar and clove oil are the heavy hitters, we support them with other essential oils, each designed to compliment the recipe, with invigorating scents and antifungal support.
To bring it all together we use commercial grade, plant-based emulsifiers and surfactants. These help the oils mix evenly with the vinegar, ensuring every spray is consistent and effective — no separation, no wasted power.
The results is a simple, effective, natural, and pleasant-to-use mould remedy that’s strong on everyday prevention and light-to-moderate build-up — without harsh chemicals, synthetic fragrances, or single-use plastic waste.
