Get rid of bathroom fungus using a simple mixture of white vinegar and water. Scrub the affected surfaces gently with a brush and rinse them thoroughly with clean water.

To clean a mouldy shower, you need to combine a targeted cleaning solution with physical scrubbing to kill the spores and remove the stains from your tiles, grout, and sealant. Start by mixing white vinegar and dish soap in a spray bottle, apply it generously to the affected areas, let it sit for twenty minutes to break down the organic growth, and then scrub the surfaces with a stiff-bristled brush before rinsing thoroughly with clean water.

Prepare the Space and Protect Yourself

Before you begin working on a shower infested with mould, you need to set up the area properly to keep yourself safe and prevent the spores from spreading to other parts of your home. Mould releases tiny spores into the air when disturbed, which can irritate your respiratory system, eyes, and skin.

Start by turning on your bathroom extractor fan or opening a window to ensure adequate ventilation throughout the cleaning process.

Put on rubber or latex cleaning gloves to protect your hands from harsh cleaning agents and the mould itself. It is also wise to wear a face mask to avoid inhaling mould spores while you are scrubbing, especially if you are working in a confined shower stall.

Next, clear out all of your personal items, such as shampoo bottles, soap dishes, razors, loofahs, and hanging caddies. Take these items out of the shower entirely so they do not get covered in cleaning residue or mould fragments. If you have plastic shower curtains or fabric liners, take them down. Fabric liners can usually be washed in a washing machine with your regular laundry detergent, while plastic curtains can be wiped down or soaked in a tub of soapy water while you focus on the shower enclosure itself.

Finally, take a dry cloth or paper towel and wipe away any loose hair, soap scum, or surface debris from the tiles and shower floor. A clean surface allows your cleaning solutions to make direct contact with the mould rather than sitting on top of everyday bathroom grime.

Apply the Cleaning Solution

Once the shower is prepped and you are properly protected, you need to apply a cleaning agent that can pene Oct 24, 2026 · do you have a good melon on your shoulder come from Crossword Clue trate the mould and begin breaking it down at the root. White vinegar is a mild acid that can kill many types of mould found in household environments without damaging most tile surfaces. Pour plain white vinegar into a spray bottle and add a few drops of liquid dish soap to help the solution cling to vertical surfaces instead of instantly running down the tiles.

Spray the entire mixture liberally over all the mouldy areas, paying special attention to the grout lines, corners, shower corners, and any silicone sealant around the base of the tub or glass doors. Do not be shy with the spray; the surfaces should look visibly wet.

If you are dealing with particularly stubborn or widespread mould, you may need something stronger. A paste made from baking soda and water works well for scrubbing away stubborn stains. Mix the baking soda and water in a small bowl until it forms a thick, spreadable paste, then use a sponge or an old cloth to smear the paste directly onto the darkest mould patches on the grout and sealant.

After applying your chosen solution, walk away and let it sit undisturbed. Giving the cleaner time to work is the most crucial step of the process. Allowing the vinegar or baking soda paste to sit for twenty to thirty minutes gives the formula time to break down the organic structures of the mould, making the physical removal stage much easier and more effective.

After the cleaning solution has had adequate time to dwell on the surfaces, it is time to tackle the physical removal of the mould. Grab a stiff-bristled cleaning brush or an old toothbrush for tighter spaces and begin scrubbing the tiles, grout lines, and corners.

Use firm, circular motions as you scrub. You will likely notice the mould starting to lift and dissolve as the bristles agitate the softened spores and the cleaning solution. Pay close attention to the grout lines, as mould tends to sink deep into the porous cement between tiles. If you used a baking soda paste, work it into the grout lines thoroughly until the paste starts to discolour as it lifts the dirt and mould out of the pores.

For silicone sealant around the edges of the shower, exercise a little bit of caution. While silicone is generally durable, using an overly abrasive metal tool or scrubbing too aggressively can tear or gouge the rubbery seal, which will eventually lead to leaks. Use a softer sponge or the nylon bristles of a brush rather than a scouring pad on silicone.

If you encounter stubborn black spots that refuse to come out of the silicone sealant, the mould may have grown underneath the surface of the rubber. In cases where mould has penetrated deep into the silicone, scrubbing alone will not remove the stain, and the sealant will eventually need to be replaced entirely once the rest of the shower is clean.

Rinse and Inspect the Surfaces

Fill a bucket with clean warm water, or use a handheld showerhead if your enclosure has one, and rinse every inch of the shower from top to bottom.

Start rinsing at the highest point of the walls and work your way down to the floor, making sure no vinegar, baking soda residue, or soapy water is left lingering in the corners or grout lines. Take your time with this step, as leftover cleaning residue can attract new dirt and soap scum very quickly.

Once the shower is fully rinsed, take a step back and carefully inspect your work. Look closely at the grout lines and the edges of the tub or shower pan. If you spot any remaining grey or black shadows, you may need to repeat the application and scrubbing process on those specific trouble spots.

Pay attention to whether the mould was merely surface-level or if it left permanent discoloration behind. Sometimes, even when mould is completely dead and gone, it leaves a dark stain on porous grout. If the area is clean to the touch but visually stained, you may need to address the discoloration separately once the area has dried out.

The final and most important step in cleaning a mouldy shower is removing excess moisture to ensure the mould does not immediately return. Mould thrives in damp, humid environments, so leaving a freshly cleaned shower wet sets the stage for spores to land and grow all over again within a matter of days.

Start by taking a squeegee and wiping down all the tile walls and glass doors to remove the bulk of the rinse water. Follow up the squeegee by taking a clean, dry microfiber towel and thoroughly drying the entire enclosure, including the fixtures, the corners, and the floor.

Next, address the humidity in the room. Keep your bathroom extractor fan running for at least thirty to forty-five minutes after you finish cleaning, or leave the bathroom door and window wide open to allow fresh air to circulate until the room feels completely dry.

To keep mould from coming back in the future, make it a daily habit to squeegee the shower walls after every use and run the ventilation fan for a short period after every shower or bath. Taking these simple preventive steps will keep your shower clean, dry, and free of mould for the long term.
