How to remove pink mould
Pink mould loves bathrooms because of their moist environments. (bathroom image by Mat Hayward from

Pink mould grows in damp, dark places and loves heat and high levels of humidity. Cleaning the surface mould is a starting point, but pink mould will return if ventilation isn't improved and/or cleaning habits subside. Pink mould will get worse and build up. If the pink mould is not prevented, black mould eventually can form and this is detrimental to your health as well as a building structure.

  1. 1

    Clean pink mould using white vinegar. Mix one part vinegar and one part water in a spray bottle. Spray the affected area liberally and let the vinegar soak for 10 to 15 minutes. Return to the bathroom and wipe off the mould. If the mould is hard to remove repeat the process and let the vinegar sit longer. You may have to do some scrubbing to get it all off.

  2. 2

    Mix baking powder and vinegar to clean your bath and shower. Pink mould is fuelled by bodily oils and scum that builds in your bathroom. Vinegar mixed with baking soda makes a paste good for scrubbing a bath or toilet. Add baking powder to vinegar until the consistency is that of a paste. Test the vinegar on a small piece of your shower tile first to make sure it will not have a negative effect on the tile. Scrub the entire area and rinse once it is free of dirt and scum.

  3. 3

    Keep humidity levels low. In some parts of the house moisture is inevitable and a fan is a helpful tool in keeping down humidity. Pink mould thrives in moist environments and will come back after cleaning if the room is not properly ventilated. Open windows and doors, place a temporary fan in the room after showers, or turn on air conditioning.

  4. 4

    Keep the light on in your bathroom to prevent additional build-up of pink mould. Mold will grow much slower in well-lit areas and thrives in the dark. Though this solution isn't permanent and certainly isn't ecologically profitable, it will help reduce the build-up of pink mould.

  5. 5

    Perform regular cleaning in your bathroom. Keep scum from building up on the grout between shower tiles, in the bath and sink. Wipe down the walls after you take a shower to hasten the drying process. Do not leave stagnant water to sit for very long; this will cause more mould growth.

Tips and warnings

  • When using chemical cleaning products or bleach in a small area be careful not to inhale fumes. Never mix bleach with ammonia and always have the room properly ventilated when cleaning.
