Firstly before any mould cleaning takes place you should really try to stop future mould growth. To do that effectively you have to make the environment it lives in difficult for it to survive. Using a dehumidifier can help make the environment less friendly for mould to grow in.
The most common places for problem black mould is in the bathroom, in or around windows and in cupboards, wardrobes or behind beds.
Because of the high humidity level bathrooms support the growth of mould at varying levels. The ceiling of your bathroom, because of high levels of condensation is a breeding ground for black mould. Often you will find mould growth in the porous grout in between tiles.
Condensation and moisture is attracted to the window and window frame because it’s the coldest part of the room. Over time it feeds the growth of black mould. Wiping down windows and windowsills when condensation occurs can help reduce the build up of mould spores.
Cupboards, wardrobes and behind beds:
Enclosed areas with little ventilation are a perfect hiding place for the growth of black mould. Opening or ventilating enclosed areas can help reduce the condensation and protect against mould growth.
Cleaning black mould can be a daily struggle. Using 1 part bleach with 4 parts water can kill off the mould. But be very careful as using bleach on a painted service can damage the paint. The grout of your bathroom tile can be a bit more difficult to clean, so soaking the grout with bleach for a few minutes before cleaning off can help. Having said that never scrape dry mould as this can release spores, and care should be taken not to breathe any mould dust or spores, especially if you are prone to respiratory problems and that includes fumes from cleaning agents also.
If you are experiencing an overgrowth of mould in any of the above areas, it may be time to seek professional help, as overexposure to mould spores or cleaning solutions can be harmful for those with respiratory issues.
