Simple everyday habits to help keep moisture under control and make your home less welcoming to mould.
That musty smell in the bathroom. Condensation collecting on the windows. A damp corner that never seems to completely dry.
Damp, mould and mildew often have one thing in common: too much moisture hanging around for too long.
So, while cleaning matters, one of the best places to start is actually before mould appears, by keeping your home well ventilated, managing moisture and staying on top of everyday build-up.
The good news? You don't need to completely overhaul your home.
Here are some simple, practical habits you can start today.
1. Let the fresh air in
One of the simplest things you can do is improve airflow.
When weather allows, open windows and doors to create cross-ventilation, particularly in rooms that tend to hold moisture.
Think:
-
Bathrooms after showers
-
Kitchens while cooking
-
Bedrooms in the morning
-
Laundries and rooms where clothes are drying
Good ventilation helps moisture escape rather than settling as condensation on walls, windows and other surfaces. Managing humidity and condensation is an important part of reducing the conditions that encourage mould growth. (SafeWork NSW)
Easy habit: Open windows for a while each morning when the weather allows instead of waiting until a room already feels damp or stuffy.
2. Get moisture out as quickly as possible
Fresh air helps, but some rooms need a little extra help.
Run your bathroom exhaust fan during showers and leave it running afterwards to help remove humid air. Use your kitchen rangehood while cooking, especially when boiling water.
And don't ignore the little sources of moisture.
Hang wet towels somewhere they can dry properly rather than leaving them in a pile. Wipe up standing water around sinks and showers. If condensation regularly collects on windows, wipe it away rather than letting it sit.
For persistently humid spaces, a dehumidifier or purpose-made moisture absorber may also help.
The goal is simple:
Don't give moisture a chance to hang around.
3. Don't wait for grime to build up
Prevention isn't only about keeping things dry.
Regular cleaning helps remove the everyday soap scum, dirt and grime that accumulate in moisture-prone areas.
Give bathroom sinks, tiles, splashbacks and other suitable surfaces a quick clean regularly rather than waiting for your big weekend clean.
Our Natural All Purpose Cleaner is a handy option for everyday maintenance around the home. Made with plant-based cleaning ingredients, it can tackle everyday grime across multiple suitable surfaces without needing a cupboard full of different cleaners.
A quick wipe today is much easier than tackling weeks of build-up later.
Tip: Always follow the product directions and check suitability before using any cleaner on painted walls, natural stone or delicate surfaces.
4. Spotted a small patch of mould? Deal with it early
If you notice a small amount of surface mould, don't simply wipe it and forget about it.
First ask:
Why is this area staying damp?
It could be condensation, poor ventilation, a leaking pipe or water getting in somewhere it shouldn't.
Cleaning the visible mould without addressing the moisture source means it's more likely to return.
For suitable washable surfaces, some households use products such as hydrogen peroxide for small cleaning jobs. If you choose to do this, always follow the product label, ventilate the area, wear appropriate protection and spot-test the surface first.
Never mix hydrogen peroxide or any cleaning product with other cleaners unless the labels specifically say it's safe to do so.
For more stubborn household cleaning jobs, Resparkle's Universal Stain Remover is another versatile option. Follow its specific directions for the surface and cleaning task you're tackling.
For extensive, recurring or hidden mould, or mould associated with significant water damage, it's better to investigate the moisture problem properly and seek professional advice rather than relying on DIY cleaning alone.
5. Try simple moisture and odour helpers
Got a musty cupboard or small enclosed space?
A few simple household options can be useful helpers.
Baking soda can help absorb unwanted odours.
Activated charcoal is another popular option for managing musty smells in enclosed spaces.
Purpose-made moisture absorbers can help collect excess moisture in wardrobes, cupboards and other small areas where airflow is limited.
Just remember: these are helpers, not fixes for an underlying damp problem.
If a cupboard is constantly damp, find out where the moisture is coming from.
6. Love indoor plants? Watch the watering
You may have heard that certain houseplants can "purify" your home or solve humidity problems.
Plants are lovely but don't rely on them as your mould-prevention strategy.
In fact, consistently wet potting mix and overwatering can add unwanted moisture to your indoor environment.
Enjoy your greenery, but:
-
Avoid overwatering
-
Empty water sitting in saucers
-
Give plants appropriate airflow
-
Check around pots and windowsills for persistent dampness
Your monstera can stay. Just don't give it responsibility for managing your bathroom humidity. 🌿
7. Pay attention to the places moisture loves
Some spots deserve a little extra attention because they regularly get wet or have limited airflow.
Keep an eye on:
-
Around bathroom sinks and showers
-
Window frames with frequent condensation
-
Behind furniture against cool external walls
-
Under kitchen and bathroom sinks
-
Laundry areas
-
Cupboards with poor airflow
-
Around leaking taps or pipes
Regularly checking these areas means you're more likely to spot moisture problems before they become bigger ones.
Your 5-Minute Daily Damp Prevention Routine
You don't need another complicated cleaning schedule.
Try building these small habits into your day:
✓ Let air circulate when weather allows
✓ Run exhaust fans after showers and while cooking
✓ Wipe away standing water and condensation
✓ Hang wet towels to dry properly
✓ Quickly clean everyday grime and build-up
Five small habits. A much less welcoming home for damp.
Prevention beats another big clean
When it comes to damp, mould and mildew, cleaning is only one piece of the puzzle.
The bigger picture is simple:
Keep moisture moving. Keep surfaces dry. Keep everyday grime under control. And investigate damp that keeps coming back.
Products like Resparkle's Natural All Purpose Cleaner can make regular cleaning easier, while the Universal Stain Remover can help tackle tougher cleaning jobs when needed.
But perhaps the most useful "natural mould hack" costs nothing at all:
Open the window. Run the fan. Dry the wet stuff.
Small habits done regularly can make a bigger difference than waiting until there's a bigger problem to clean.
