When black or green patches appear on tile grout, silicone seals, or painted walls, wiping them superficially often fails to eliminate the root cause. Using a brush allows you to reach into textured surfaces, grout lines, and microscopic crevices where spores take root. Tackling this task requires patience, the right physical tools, and a systematic approach to ensure the room becomes genuinely clean.

Mould spores easily become airborne when disturbed, so closing off the bathroom and opening a window or running an exhaust fan creates necessary ventilation. Put on rubber gloves to shield your skin from cleaning agents and mould irritants. Wearing a basic dust mask or facial covering prevents you from inhaling loose spores while you work.

Clear out all toiletries, bath mats, and towels from the immediate area so they do not get splashed with cleaning solutions or stray debris. If you are working near a fabric shower curtain, take it down and wash it separately, or discard it if the fabric is heavily infested. Lay down old towels or plastic sheeting beneath the work area to catch any drips, dirty water, or falling debris. Having everything organized and accessible prevents you from scrambling for supplies mid-task and helps contain the mess.

Creating the right liquid cleanser is essential for breaking down the organic matter of the mould before you start scrubbing. Combine equal parts white vinegar and warm water in a clean spray bottle, or mix ordinary washing soda with warm water in a bucket to form a gentle, mildly alkaline paste. Vinegar works well on non-porous surfaces like ceramic tiles and glass because its acidity disrupts the cellular structure of the mould.

If you encounter stubborn stains on hard white ceramic, a mild chlorine bleach solution diluted with water can remove the discoloration, though it merely bleaches the pigment of certain surfaces rather than killing deep-seated roots. Avoid mixing different household cleaners together, particularly bleach and vinegar or bleach and ammonia, as this creates hazardous fumes. For most general bathroom scrubbing tasks, a simple mixture of warm water and liquid dish soap combined with vinegar provides a safe and effective base for loosening grime and spores.

Apply the solution and let it sit

Once your solution is ready, apply it generously to every visible patch of mould. If you are using a spray bottle, coat the tiles, grout, and corners until the surfaces are thoroughly wet. For thicker pastes or vertical walls, use a sponge or cloth to press the mixture gently into the mould without rubbing it yet.

Allow the liquid to sit undisturbed for at least fifteen minutes. This dwell time gives the cleaner a chance to penetrate the surface layers of the fungus, softening its grip on the grout or sealant. If the surface dries out too quickly during this waiting period, mist it lightly with a bit more warm water. Giving the solution time to work minimizes the physical effort required during the scrubbing phase, as the chemical agents loosen the stubborn attachment of the spores to the wall.

Pay special attention to corners, grout intersections, and the edges where the bathtub meets the wall, as these spots accumulate soap scum that feeds new mould growth. For very narrow grout lines, a smaller utility brush or an old toothbrush helps you maneuver into tight spaces. Apply steady pressure as you scrub, watching the dark spots begin to lift and dissolve away from the surface. If a particular patch resists your efforts, apply a little more of your cleaning solution, let it sit for another few moments, and scrub again with renewed vigor.

Rinse away the residue

After thoroughly scrubbing every affected area, you need to wash away the dislodged mould, dirt, and leftover cleaning solution. Fill a clean bucket with fresh warm water and use a clean sponge or cloth to wipe down all the surfaces you just scrubbed. Rinse the sponge frequently in the clean water to ensure you are actually removing the debris rather than just spreading it around.

If you have a handheld shower attachment, you can use a gentle stream of warm water to rinse down tiled walls and shower enclosures directly. Make sure to flush out all the loosened particles from the grout lines and corners. Leaving dirty residue behind invites the mould to return quickly, as leftover soap scum and organic matter provide a ready-made food source for new spores. Once the rinse water runs clear and no suds or discoloration remain, you are ready for the final steps.

Dry the area completely

Moisture is the single greatest ally of mould, so leaving a bathroom damp after cleaning guarantees a quick return of the problem. Take a clean, dry microfiber cloth or towel and wipe down all the surfaces you just washed and rinsed. Pay careful attention to horizontal ledges, window sills, and the bottom corners of the shower where water naturally pools.

Keep your exhaust fan running continuously for at least an hour after you finish cleaning, or leave the bathroom door and window wide open to encourage cross-ventilation.

Empty your bucket of dirty water down the toilet or a utility sink, and rinse the bucket thoroughly with clean water. Wash your scrub brush under running water to remove any trapped hair, soap scum, or mould fragments lodged between the bristles, then leave it in a sunny, well-ventilated spot to dry out completely.

Remove your gloves, wash your hands thoroughly with soap and water, and dispose of any heavily soiled paper towels or disposable cloths in a sealed trash bag. Wash any reusable cotton rags or towels in a hot water cycle with laundry detergent to kill any lingering spores clinging to the fabric. Taking these final cleanup steps ensures your bathroom remains genuinely clean and your cleaning gear is ready for future maintenance.
