How to Remove Mould on Grout & Caulking

Bathrooms are prime ‘hot spots’ for household mould.

Your bathroom can be a breeding ground for mould and mildew, largely due to poor ventilation, water and humidity sources.  Use Concrobium Mould Control to eliminate mould in shower stalls, bath tubs, behind toilets, in cabinets and on ceilings, tiles and walls.

  •   Solution
    1. Spray Concrobium Mould Control on the affected caulking & grout and allow to dry. Make sure the surface is completely dry prior to application.
    2. Because tile grout and caulking is quite porous, mould that has grown into it over the course of time may be very difficult to remove. Use Concrobium Mould Control with a stiff bristle brush to scrub the affected surface to eliminate tile grout mould.
    3. For tough and embedded black mould stains, try our Concrobium Mould Stain Eraser. If grout is very mould-stained, you may need to reapply the Concrobium Mould Stain Eraser and apply a light agitation. If these attempts are unsuccessful, you may need to replace the grout/caulking altogether. Spray Concrobium into the cavities once you’ve removed the grout/caulking – and then spray the newly-applied grout for mould prevention.
    4. Finally, re-apply Concrobium to leave a thin layer of the solution on the surface to protect against mould. Reapply as required, depending on the amount of dousing the surface receives.

    NOTE: As bathrooms receive repeated exposure to water and humidity, you may be required to reapply the product every 1-2 months or as required to ensure resistance against mould re-growth.

  •   Tip

    Help prevent mould by ensuring proper bathroom ventilation. Ensure a ventilation fan is properly installed and run it often to reduce bathroom humidity.
