How To Get Rid Of Black Mould

It was a funny line in the movie, “Guess Who“, but having black mould in your home or investment property is a serious problem that can cause significant health issues to anyone who is exposed to it. Mould is a type of fungus and it usually appears in areas where moisture is also present. Here are some quick tips on how you can remove black mould in your house or your building.

Borax Solution:

  • Dissolve a cup of borax in 4litres of water. Put it in a spray bottle and spray it on the affected area. This would work if the moulds are on materials like tiles and even wood. You could also use this solution on glass areas.
  • Once you sprayed it on the affected area, you can get a brush and scrub the surface thoroughly. Make sure that you wear protective gloves and mask because it could jeopardise your health if you inhale it. The particles of black mould could cause some permanent damage to your respiratory system and other vital parts of your body, as soon as it gets into your bloodstream.
  •  Remember to not rinse it once you’re done applying it. Instead, wipe it with another rag or cloth. You need to do this in order for the mould’s spores to die and not encourage its growth, as the borax will stop all of that from happening.

Laundry Detergent Solution:

  • Another option you have is to use a simple laundry detergent solution. I would prefer the powder ones because it could be more concentrated once you mixed it with water. One cup of it would do alongside 4 litres of water.
  • You could use a spray bottle once again to apply it on the affected part. Get a scrub and rub the area thoroughly. This time, you are allowed to rinse it.

Kill It Using Hydrogen Peroxide:

  • The advantage of going for this option is that it would work on all kinds of surface, both porous and nonporous. You don’t have to worry about it being toxic as well, especially if you have pets or children living with you.
  •  Use a spray bottle once again and fill it up with hydrogen peroxide. There’s no need to add water. Spray it on the affected part and leave it for half an hour. Get a clean rag or cloth to wipe the area. Don’t rinse because the hydrogen peroxide would also stop the spores from growing.
Never delay in taking action, as soon as you find out that your place has mould. Keep in mind that this could cause some permanent damage to a person’s health. Black mould is toxic and should not be a part of your living space. The process of killing the mould may need to be repeated and you may need to take measures to make the environment less susceptible to mould by ensuring that there are no conditions that encourage moisture. Things that reduce the growth of mould are natural sunlight, good ventilation and waterproof conditions.
If you are not able to solve this issue on your own, it is best to hire a professional to take care of it.
