Let’s Get Started!
1. White Vinegar + Warm, Soapy Water

Swap your traditional mould removals and products containing ammonia with this environmentally friendly cleaning solution. White vinegar is a powerful cleaning product that naturally fights mould spores- all thanks to its antimicrobial properties. The vinegar's acetic acid works wonders by creating an acidic environment that can help banish all types of mould and mildew stains from surfaces. It disrupts the microbial cell membranes, accelerating the removal process.
Combine it with warm water and dishwashing liquid soap to heave the DIY product's effectiveness. Try to use a cup of undiluted white vinegar with at least 5 per cent of acidity. Pour this into a spray bottle and apply it to the affected area. Leave it for a few minutes until you scrub it with a soft bristled brush or sponge. Ensure you rinse and dry the surface to stop mould infestation from coming back. You can use this spray on showers, curtains, ceiling walls, carpets, etc.
Note: Do not use vinegar on natural stone surfaces and delicate areas, such as limestone countertops, tiles, grout lines, etc.
2. Hydrogen Peroxide: Works as Magic
Widely known as an effective mould remover, hydrogen peroxide possesses strong oxidizing properties that help deliver exceptional results. It can combat almost all types of mould and mildew species by breaking down its cellular structure, preventing further growth and spread.
The best part is that you can use it on tiles and grout lines as well. Spray 3% hydrogen peroxide onto the mould stains and leave it for a few minutes. Next, scrub the surface with an old toothbrush and work in a circular motion. Rinse and dry the area to see spotless results.
However, it is important to ensure proper ventilation to prevent toxic fumes and other potential side effects. It is good to check the source of bathroom condensation and fix water leaks before the arrival of professionals for a budget end of lease cleaning Sydney. This can increase the chances of bond return without any downtime.
3. Tea Tree Oil: Natural Antifungal Remedy
Tea tree oil is best known for its antimicrobial and antifungal properties that can do wonders in banishing stubborn mould and mildew stains from different surfaces. It not only spreads fresh aroma but also removes germs and bacteria effectively. Mix 10-15 drops of tea tree oil and two cups of water in a spray bottle and apply it on the affected area. Let it rest for a few minutes or until you scrub it with a brush. Like vinegar, tea tree oil has a strong smell that can elevate the overall feel of your home.
4. Baking Soda: Tackle Mould Naturally
This is a fantastic remedy to eliminate mould and mildew stains from non porous surfaces like glass and sinks. You can dissolve a cup of baking soda into warm water and apply it on the affected surface. Preparing a thick paste can also deliver results. Let it sit for half an hour, and wipe it with a wet cloth. It can also banish unpleasant odours while leaving the surface spotless. You can use it to clean painted walls, inside your oven, microwave, and grout lines.
5. Borax: A Great Mould Inhibitor
Its alkaline properties can disrupt mould and mildew infestation and kill fungus effectively. To prep the solution, take one cup of borax powder with one gallon of warm water. Mix it well and spray it on the surface. Allow it to sit for 10 minutes before scrubbing the stain away. Rinse with clean water and dry the surface. If you want a meticulous end of lease cleaning Sydney service for the final inspection, do proper research, ask relevant questions and make an informed decision. This can help you secure full bond money without any rental dispute or disagreement over cleaning.
