Bathroom Mould Removal: How to Remove Mould from the Shower & Ceiling

Mould can make your bathroom look dirty, even after you've cleaned! Find out how to banish mould from the bathroom ceiling & shower with this handy guide.


Listen here

Your toilet is clean, your bathtub is sparkling, but what about your walls and tiles? In steamy, damp, and humid rooms such as the bathroom, mould can easily form on walls and tiles, which can make them look dirty – even when they’ve just been cleaned. If you don’t know how to remove mould from shower, ceiling & tile areas, don’t worry. Bathroom mould removal is actually much simpler than you think.

Use Domestos bleach to remove any lingering traces of mould microbes from your bathroom ceiling and shower tiles*. Although the discolouration may have been cleaned away, if any spores remain, mould can easily grow back. Always follow the manufacturer’s instructions when using bleach, and wear protective clothing such as gloves and a face mask if necessary. It’s also a good idea to test bleach on a small area first to ensure it doesn’t damage or discolour your bathroom paint.

Key Steps for Bathroom Mould Removal

If you want to know how to remove mould from bathroom ceiling, shower, and tiles – here’s a simple 3-part process:

  • Step 1: Get Rid of Discolouration

The most common type of mould to grow in bathrooms is black mould, which can make your bathroom look grubby even when it’s perfectly clean. That’s why focusing on getting rid of this discolouration first can make you feel much better. Begin by spraying your bathroom tiles with a product such as Jif Bathroom Spray – with its deep cleaning molecules, it will immediately start to lift away tough stains, leaving surfaces looking much brighter.

  • Step 2: Clean Away Mould Spores

Cleaning sprays can be very effective, but it may not be able to remove all the microbes. The problem with this is that if some microbes remain, mould can quickly and easy grow back and you’ll be back at step 1. No one wants that. You can easily remove more microbes by using a powerful bleach product. For bathroom mould removal from walls, look for bleach that’s thick and has high viscosity like Domestos* disinfectant, so that it clings to the wall – the watery stuff will just run down the floor and leave a messy puddle. Dilute if necessary, apply to a cloth, and wipe across all affected areas. Some people like to use homemade solutions for removing mould, like vinegar – but remember to always avoid mixing vinegar and bleach, as the combination will release toxic fumes.

Safety Warning

Do not swallow; do not mix with other detergents or chemicals, particularly cleaners. Mixing may generate toxic chlorine gas. Ensure adequate ventilation when using, vapour may be harmful. Strongly alkaline and corrosive. Attacks skin and eyes so avoid contact. May produce severe burns. Wear protective gloves and eye protection when mixing or using. Do not mix with hot water. Store upright below 25 degrees celsius. Rinse containers with water before disposal.

 *Domestos kills germs such as:

  • Pseudomonas aeruginosa

  • Escherichia coli

  • Staphylococcus aureus

  • Proteus vulgaris

  • Step 3: Scrub Away the Stubborn Stains

If you’re left with a few stubborn stains – particularly mould in the shower or between your tiles where it’s hard for a cloth to reach – try using a thin, stiff-bristled brush. An old toothbrush works really well, but just remember to throw it out afterwards so you don’t accidentally use it when you’re half asleep in the morning! Apply a little more bleach, and use the brush to vigorously scrub at the most problematic areas before rinsing thoroughly. In some very bad cases, you may not be able to remove the entire discolouration, but the mould microbes should have successfully been removed from the tiles.

Now that you know how to get rid of mould in the shower and all areas of the bathroom, it’s also important to understand the best ways to prevent the mould from coming back. In humid areas like the bathroom and kitchen, stopping mould growth completely can be difficult – but it’s not impossible. Keep the bathroom as well ventilated as possible – keep windows open, for example, or install an extractor fan to draw moisture out. Remember – preventing mould growth means you won’t have to clean it off again in the future.
