Mould is a fungus that grows in damp and humid areas with high moisture levels.
To remove mould in bathrooms you can use diluted bleach, vinegar, borax or hydrogen peroxide. Make sure you follow the directions carefully. Also, always ventilate the bathroom while you are cleaning it. To make your own cleaning solution, mix even amounts of water and bleach. You can also use vinegar or hydrogen peroxide in the same way. Make sure you wear gloves rather than bare hands when tending to the affected area and use a little elbow grease to get into small crevices.
Excess moisture normally causes mould. This can be from showers, baths, toilets, or even hand washing. If you don't ventilate the bathroom well after using it, the ventilation mould will start to grow. You can prevent this by opening a window or running the exhaust fan after you shower or bathe. You should also wipe down the wet surfaces in your bathroom, like the sink, counter, and tub to help stop mould growth. If you see mould growing, clean it right away with a scrubbing brush. A good way to ensure no mould spores can build up in your bathroom is to keep it as dry as possible. This means using a shower curtain or door, and not let any water accumulate on the floor.
You can use bleach diluted with water. Diluted white vinegar or baking soda may also work well. Apply this to the mouldy area with a sponge or cloth and scrub it away. There is a range of commercial products you can simply spray and wipe clean to get rid of mould.
Mould is a fungus that grows in damp and humid areas with high moisture levels. It is often found in bathrooms because of the moisture. Mould can be different colours, but it is usually black, green, or brown. It may make you sick if you breathe it in, so it's important to keep on top of it with regular cleaning of the entire area using appropriate cleaning products.
Mould can cause respiratory infections, allergies, asthma and skin irritation. If you have mould in your bathroom, it's important to clean it up right away.
If the mould has soaked into porous surfaces like drywall or wood, you will need to have it professionally cleaned and perhaps replaced. Sometimes the musty smell cannot be removed easily, even with a vinegar solution or silicone sealant.
Waterproof paint can help to prevent mould, but it is not a guarantee. Mould can still grow if there is too much moisture in the air, even on some non-porous surfaces. Waterproof paint is a good idea but you need to address the source of the moisture to make sure the mould doesn't come back.
The cost of having a professional clean your bathroom will depend on the size of the room and the severity of the mould problem. However, you can expect to pay at least $100 for a small bathroom.
If you're willing to put in the time and effort, then yes, you can renovate a bathroom yourself to remove mould. However, it's important to be aware that this is a big project requiring some planning and preparation. There are also some health and safety considerations to keep in mind, as mould can be harmful to your health.
If you do decide to tackle this project yourself, the first step is to identify the source of where the mould feeds. Once you've identified the source, you can start taking steps to fix it. For example, if there's a leaky pipe, you'll need to repair that before you can start cleaning up the mould.
Once you've fixed the source of the problem, you can start cleaning the mouldy areas. This will require some scrubbing, and you may need to use a strong cleaner or bleach to get rid of all the mould. Once you've cleaned up the mould, make sure to keep the area well-ventilated so that mould doesn't have a chance to come back. There's some handy information on mould at NSW Health.
