Hey there,
If you’re dealing with mould in your bathroom, you’re definitely not alone. Here in Australia, especially in the humid Northern Rivers where we are, mould is basically a household member whether we like it or not.
So the question I get asked all the time is: Should I try to deal with mould myself (DIY), or should I call in the professionals?
Here’s my honest take.
When DIY makes Sense
The simple answer is that most of the time, yes — you can absolutely tackle mould yourself, especially if it’s just surface stuff in the shower or on tiles.
I’ve found DIY works really well when:
- The mouldy area is fairly small (not covering a whole wall)
- It’s on tiles, glass, or sealed grout
- There’s no major water damage or hidden mould behind the walls
For everyday bathroom mould, rolling up your sleeves and handling it yourself is often the smartest move.
My Go-To, DIY Method for Dealing with Mould
If you’re doing it yourself, here’s the approach we use at home (the one Nana would approve of):
- Fix the moisture first — open windows, use a fan, squeegee the shower after every use.
- Baking soda paste trick (this is a game changer):
- Mix baking soda with a little water into a thin paste.
- Spread it over the mouldy spots.
- Spray Nana's Anti-Mould Solution over the baking soda and let it fizz for 15–30 minutes.
- Wipe or gently scrub (with a cloth) clean.
- To help prevent mould returning, at least once a week, spray the area with Nana's Anti-Mould Solution.
It’s surprisingly effective and uses simple, natural ingredients.
Why I Recommend Nana’s Anti-Mould Solution
When it comes to the spray itself, I’m really particular. I created Nana’s Remedy Co. because I wanted to provide effective cleaning products that don't fill the house with toxins.
Unlike many commercial mould sprays, Nana’s contains no harsh chemicals, no bleach, no ammonia — nothing nasty that could affect your family, kids, or pets. It’s made with vinegar and a careful blend of essential oils, particularly clove oil, which goes deeper than surface cleaning. Clove (along with tea tree and lemon myrtle) helps fight mould at a deeper level, not just masking the problem.
It’s effective, but gentle enough that I feel comfortable using it around my own family
Warning Signs You May Need Professional Help
That said, there are times when DIY isn’t the best idea. I’d get professional help if:
- The mould is spreading over a large area
- You can smell it but can’t see where it’s coming from
- There’s dampness in the walls or ceiling
- Anyone in the house has asthma or breathing issues
In those situations, it’s better to fix the root cause properly rather than just cleaning the surface.
The Bottom Line
For most of us dealing with normal bathroom mould, DIY is absolutely worth doing. It saves money, avoids harsh chemicals, and honestly feels pretty satisfying when you see the difference.
