How to Get Rid of Bathroom Mould Without Bleach

The battle against mould can be exhausting. For years, we’ve been told to smother our mould in bleach. But here’s some news. Bleach is not only a health hazard; it actually doesn’t treat the problem effectively.

According to the ABC’s resident mycologist Dr Neumeister-Kemp, bleach is just temporarily covering up your mould issue:

“The fungi contain melanin, and the bleach just takes the colour out, but the fungi are still there, you are just masking it… Six weeks later it appears to come back, but it was never gone.”


So, now you’re back to square one. How to tackle that mould issue? What if I told you that there was a natural alternative that will actually work for you?

Read on.

How to Get Rid of Bathroom Mould

The four products you need:

White vinegar
Tea tree oil
Hydrogen Peroxide
Bi-Carb soda

Hydrogen Peroxide

You may not know that hydrogen peroxide is anti-fungal, anti-viral and anti-bacterial. The trick here is to pour 3% concentration hydrogen peroxide into a spray bottle, generously spray the mould and let it sit for around 15 minutes. Scrub and rinse thoroughly with water.

Bi-Carb Soda

As a natural disinfectant, Bi-Carb soda can be used to kill mould on non-porous surfaces. We recommend vinegar on your porous surfaces such as gyprock walls.

Combine a teaspoon of Bi-Carb in a spray bottle of water and shake. Spray into the surface, scrub and rinse!

Vinegar & Tea Tree Oil

This one is the simplest, and the most effective. As a mild acid, vinegar will kill the mould. Dr Neumeister-Kemp explains why.

"The vinegar attacks the fungi mechanically, so it actually, via osmosis, penetrates into the structure and explodes it, so you actually kill the fungi."


The vinegar attacks the source of the mould problem and is able to kill the spores.

Tea Tree Oil has antimicrobial properties, so it’s also a great mould killer. Combining these two natural mould busters will get the job done!

In a 500ml spray bottle, add about 30 drops of tea tree oil.

For a mild/small mould problem: Spray the solution on the mould and let it sit for 15 minutes before you wipe it clean.

For a bigger mould issue: You’ll need to let the solution sit for an hour. Keep in mind that you’ll have to reapply a couple of times as the solution may run off the surface throughout the hour.

Note that this process may need to be repeated over a few weeks until the mould is totally gone.
