Remove the mouldy stuff

You can wash them in a bleach-saturated load of laundry; however, it’s recommended to entirely discard the mould-affected items, as they may pose a risk of contaminating other parts of your home. Remember to photograph them or add in inventory before disposing of them, just in case you need to involve your insurance company.

Scrub off mould

This is because the dusty spores can become airborne and are even more dangerous as you at a high risk of inhaling them. You can use a spray bottle filled with cool water to dampen the mould, but be careful not to over-saturate it, or it can aggravate your problem.

A bristled brush or a scrub can be used to remove mould using a solution of dish soap and water. Next, take a clean rag and wipe the soapy area with a solution of bleach and water in equal quantities. Discard the items properly after use.

After scrubbing

After cleaning the mould, check the exposed plumbing again for leaks and drains for any clogs. Also, ensure that the seal around your windows is appropriately tightened. Moreover, after scrubbing off the mould and disinfecting the surface, seal your walls with a primer that contains a moisture barrier.
