Clean and Remove Mold: First, scrub away any visible mold using a mixture of water and a mold-killing cleaner like bleach or a commercial mold remover. Wearing gloves, a mask, and goggles is essential to protect yourself from mold spores during this process.
To use the bleach solution, mix one-part bleach to one-part water and apply the solution with a cloth. To use vinegar, pour it into a spray bottle and spray it directly onto the mould. Leave it for an hour or so, and then wipe the area clean with water and wait for it to dry.
