This effective method requires no scraping and no removing and replacing the sealant. Black mould is unsightly and unhealthy. Once it has a hold, it is difficult to remove using standard cleaners, mould removal sprays or liquids.
This easy method requires four easily available household items:
- thick strong bleach;
- sheets of toilet paper;
- protection for your hands;
and
- cotton wool balls unravelled.
The tissue/cotton wool keeps the bleach in place against the mould. You need to leave the bleach in place for 12 to 18 hours. (Possibly overnight.) Wearing protective gloves, remove tissue/cotton wool and dispose of safely. Always wear protection when handling bleach and follow the instructions on the bottle.
