To clean mold from the ceiling, wash the affected area with a store-bought mold cleaner, or a mixture of dish soap and water. Let the area dry. Now it’s time to get out the big guns to kill the mold—bleach. Mix one-quarter cup of bleach with one quart of water and apply the solution with a spray bottle or sponge.
The best way to remove mould from bathroom ceilings is to use a simple solution of warm water with detergent or a homemade cleaning solution of diluted bleach or white vinegar. Before you start cleaning the area, be sure to wear a protective mask and gloves so that you don’t touch or inhale the mould spores.
