The atmosphere in your house contains mould spores — fungi which need moisture in order to grow. You don’t dry them immediately, especially if your house is warm and humid and if your walls get wet, mould spores can begin to grow. Spore expansion leads to mould, which looks like little black spots. If left untreated, paint can be penetrated by mildew. Drying the area and cleaning walls with bleach and water can help remove spores and prevent them.
Ratio for Mixing
The measurements for a bleach solution are 1 part liquid chlorine bleach to 3 parts water. To make enough for a large spray bottle, combine 1/2 cup bleach to 1 quart water. If desired, add a squirt of dishwashing liquid. Cover with a dropcloth , open all the windows in the room and turn on a fan. Wear gloves to protect goggles to protect your eyes, your hands, a mask to protect your lungs and old clothes on. Clean away the mould.
Keep Mildew From Coming Back
It involves drying out the room to prevent further mold infestation. If your walls have suffered water damage, seek the services of a mould cleaning professional. But if the mould is restricted to a region of the wall, then a fan or dehumidifier can keep mold. Removing mould can require cleanings. To help remove mildew stains that are tough, permit the bleach solution to sit down for a couple of minutes in between cleanings.
