Dampness can occur due to a leaky roof or faulty plumbing. Also, brick walls have the ability to hold a lot of moisture, especially during monsoon and winter. To avoid the formation of black mould on your brick walls, follow the step-by-step guide mentioned below.
Clear. Using a rag, dust the wall and clear all the dust and dirt.
Prep work. Warm 3 cups of water and add 5 cups of vinegar to it. Soak the sponge for the next move.
Cleaning. Wring the sponge to remove excess solution and scrub the affected area in a circular motion. If the sponge dries out, soak, squeeze and repeat.
Last move. Soak another cloth with hot water and wipe it all over the surface. Dry the portion with an air dryer.
