How to Clean Mold From Wallpaper

Mix together a cleaning solution of 1 cup water and 1/2 cup distilled white vinegar. Pour this solution into a bucket or a spray bottle. Alternatively, you can mix together 1 drop of tea tree oil and 1 cup of water for your cleaning solution.

Mist a clean sponge with the solution, or dip the sponge into the bucket and wring it out thoroughly. Wear rubber gloves to protect your hands while cleaning the walls.

Rub the sponge onto the molded area to clean, and gently scrub away the mold. Test the mixture in an inconspicuous area, such as behind a door or in a corner of the room, to make sure the solution won't damage your wallpaper. If the wallpaper is unharmed, continue to the rest of the room.

Move the sponge in small circles, and do not soak the wallpaper. It should be damp but not too wet.

Wipe the wall off with a damp sponge dipped in clean water, and dry with a soft cloth. Allow the wall to air dry before washing again. Continue until you have removed the mold.
