5 Ways to Get Rid of Mould in the Shower
Your bathroom is a perfect breeding ground for mould since it is typically dark and wet – two conditions that mould loves. You could find it on the walls of your bathroom, in the corners of your shower or even on wet tiles.
To prevent them, you can use common household items like vinegar, baking soda, hydrogen peroxide, and bleach.
1. Use Vinegar Mixture

Tools Needed: White vinegar, an empty spray bottle, a scrubbing brush or sponge, gloves, and a clean cloth.
Steps to Follow:
- Pour undiluted white vinegar into a spray bottle—no need to mix it with water as vinegar works best in its full strength.
- Spray the affected areas generously, ensuring you cover all visible mould spots.
- Let it sit for at least one hour. The vinegar needs time to penetrate and break down the mould.
- Scrub the area using a scrubbing brush or sponge to remove the loosened mould.
- Wipe the area with a clean cloth to remove residue, and then rinse thoroughly with warm water.
2. Baking Soda

Tools Needed: Baking soda, water, a mixing bowl, a scrubbing brush or sponge, and a cloth.
Steps to Follow:
- Mix a thick paste using 2 parts baking soda and 1 part water in a bowl. Adjust the amount depending on the mouldy area size.
- Apply the paste generously to the affected areas using your hands (with gloves) or a sponge.
- Scrub thoroughly with a brush, paying extra attention to corners and grout lines.
- Rinse the area with warm water and wipe away any residue with a cloth.
- If stubborn spots remain, reapply the paste and repeat the scrubbing process.
3. Hydrogen peroxide

Tools Needed: 3% hydrogen peroxide (easily available at pharmacies), a spray bottle, gloves, and a sponge or cloth.
Note that hydrogen peroxide can bleach certain surfaces, so test it on a small, inconspicuous area first.
Steps to Follow:
- Pour 3% hydrogen peroxide into a spray bottle. Do not dilute it.
- Spray the mouldy areas until they’re fully saturated.
- Allow the solution to sit for about 10 minutes to kill the mould and loosen stains.
- Scrub the area with a sponge or cloth to remove any remaining mould.
- Wipe clean with a damp cloth and let it air dry.
4. Bleach Solution for Stubborn Mould

Tools Needed: Bleach, water, a spray bottle, a scrubbing brush, gloves, and ventilation (open windows or fans).
Never mix bleach with other cleaning products, especially vinegar or ammonia, as it can create dangerous fumes.
Steps to Follow:
- Mix one part bleach with ten parts water in a spray bottle.
- Spray the solution on the mouldy area, ensuring good coverage.
- Let it sit for about 15 minutes to break down the mould.
- Scrub thoroughly with a brush to remove the mould stains.
- Rinse the area with warm water and dry it with a clean cloth.
5. Commercial Mould Cleaner

Tools Needed: A mould-specific cleaner (available at stores), gloves, a sponge, and a cloth.
Look for cleaners labeled as safe for bathrooms and tiles to avoid damaging surfaces.
Steps to Follow:
- Read the label instructions carefully to ensure proper usage and safety precautions.
- Apply the cleaner to the affected areas as directed.
- Allow the cleaner to sit for the recommended time.
- Scrub the area with a sponge to remove the mould.
- Wipe it clean with a damp cloth and dry thoroughly.
Surely, these DIY methods can be a starting point and temporary relief for minor mould issues. However, for severe infestations, it’s strongly advised to hire experts who have the equipment and skills to handle mould safely and effectively.
How to Keep Your Bathroom Mould Free?

Here’s how you can stay one step ahead of mould and enjoy a cleaner, healthier bathroom.
1. Set Up Proper Ventilation
Ventilation is your first line of defense against mould. Without proper airflow, moisture lingers, creating a breeding ground for mould spores.
Start by ensuring you have a functional exhaust fan and use it every time you shower. Let it run for at least 15–20 minutes after you’re done to remove excess steam.
If your bathroom has windows, open them during and after your shower to allow fresh air to circulate. This helps dry out the room faster, reducing the chances of mould growth.
2. Wipe Down Wet Surfaces
Keep a squeegee handy and use it to remove excess water from tiles, shower walls, and glass doors after every shower. This simple step prevents water from pooling and reduces the dampness that mould loves.
Pay special attention to grout lines, corners, and edges where water tends to collect. Less standing water means fewer opportunities for mould to take hold.
3. Clean Your Shower Head
When you ignore mould shower growth, it can also eat away at surfaces and weaken the structure of your bathroom.
One area often overlooked is the shower head, which can accumulate mould and mineral deposits over time. Knowing how to clean a shower head effectively can help prevent mould from spreading.
4. Use Dehumidifier or Moisture Absorber
A dehumidifier device pulls excess moisture from the air, making the environment less inviting for mould.
Alternatively, you can use moisture-absorbing products like silica gel packs or humidity-reducing tablets. Place them in corners, on shelves, or near areas prone to dampness.
5. Repair Any Leaks
Leaky pipes and fixtures can create hidden mould problems that go unnoticed until it’s too late. Even minor drips contribute to persistent moisture, which encourages mould growth.
Keep an eye out for signs of hidden leaks, such as discoloration on walls, ceilings, or floors.
6. Use Mould-Resistant Products
If you’re remodeling or upgrading your bathroom, mould-resistant paints are specially formulated to prevent mould from growing on walls and ceilings.
These are great options for high-moisture areas like bathrooms. Seal tiles and fixtures with mould-resistant caulk to keep moisture from seeping into cracks and crevices.
