A step-by-step guide to using Delete Mould and Mould Master effectively
If you’ve discovered mould at home or in your workplace, you’re not alone. The key to removing it successfully is choosing the right product and applying it properly. Here’s how to get the most out of Delete Mould and Mould Master.
How to Use Delete Mould Safely and Effectively
Delete Mould is ideal for hard surfaces with visible mould build-up. It works quickly and provides a deep, long-lasting clean.
Step 1: Prepare the area
Wipe away dirt or loose debris. Make sure the space is well-ventilated. Open windows or use an exhaust fan where possible.
Step 2: Transfer the product
Pour Delete Mould into a spray bottle or pressuriser for easier application.
Step 3: Apply to the mould
Spray directly onto the affected area.
- For indoor use (walls, grout, showers): leave for at least 20 minutes
- For outdoor use (concrete, driveways, fences): leave for at least 60 minute
If ventilation is limited indoors, we recommend exiting the room while the product works. It has a strong odour and should not be inhaled for long periods.
Step 4: Rinse or wipe away
After letting it sit, rinse the surface with clean water. For stubborn mould, you may need to scrub and repeat the process.

What people are saying
I have to say, I was a bit sceptical buying this product, as I don’t like to use bleach. I moved into a rental and I was so frustrated with a spot that nothing worked on, I thought I would give bleach a go again. But not even the super strong supermarkets and Bunnings bleach products worked. So for the last time before I throw my hands up in the air and give up, I gave this a go. I saw some comments on the Mums Who Clean site about the Bushbys. Oh my! It worked! It took a few times – but it has worked!! Thank you so so soooooo much! You have made me happier that I can say ~ Mary Francis
Used this today on the ceiling in the bathroom. Had a serious mould problem on the whole ceiling. Should have taken before and after pics. It is like the mould was never there. Can’t believe how good it works. Obviously has a pretty strong smell and it’s important to use protective equipment but so worth it. ~ Rebecca Lousie Hurcom
I bought the mould spray and so far after almost a year no signs of mould! Worth the purchase! Thank you. ~ Leisa Stanford
Using Mould Master for Gentle Cleaning and Prevention
Mould Master is a versatile, low-fume formula that is safe for all types of surfaces and materials. It can be used to clean mould and also works as a preventative treatment in areas prone to moisture.
How it works
Mould Master uses a blend of raw materials that are highly effective against mould, algae, and bacteria. The formula is pH neutral, odour-controlling, and multipurpose. It can be sprayed, wiped, poured, or mopped onto surfaces.
Where to use it

Prevent Mould From Coming Back
Once you’ve cleaned the affected area, it’s important to maintain a clean, dry environment. In wet areas like bathrooms, pair Mould Master with Bushby’s SHOWER PRO to keep soap scum and water scale under control.

Good ventilation
Proper airflow dilutes and disperses moisture-rich air, making it much harder for mould spores to settle and multiply. aaa standard services
Regular cleaning
Consistent wiping and drying—especially after spills—interrupt the conditions mould needs to thrive and the right products can help you stay on top of mould before it becomes a bigger problem. Envirovent
