Create a baking soda paste with water and apply it to mold spots. Leave it for an hour, then scrub with a stiff brush. Follow with a soap solution to complete the cleaning. Rinse with vinegar water to eliminate mold and black spots permanently. Wipe with a clean, dry cloth and let the area air dry. Ingredients like ethyl alcohol or ammonia can also be effective against mold.
Safety First: Wear gloves and a mask to protect yourself from harmful spores during this sensitive cleaning process.
