Instructions
Vacuum the surface of the dartboard to remove any dust or debris.
Use a soft but stuff brush to remove embedded dust and dirt from the surface.
Examine the dartboard for moisture damage, including mildew and mold. If you find mold or mildew, your board may be damaged beyond repair. However, if it is just mold found on the surface, you may be able to save it.
Take a moldy dartboard outside so that mold spores are not spread around your home.
Use a can of compressed air to blow the mold and mildew spores, as well as any other dust, out of the board.
Leave the dartboard in direct sunlight for a day or two to kill the mold or mildew. Bring it into the garage overnight so that dew or frost does not settle on it. Sunlight may cause the dartboard to fade slightly, but this is better than having mold or mildew on it.
Dampen a clean cloth with wood polish and gently wipe it on the surface of the dartboard. Do not soak the board with the polish.
Allow it to dry thoroughly, at least overnight, before using.
Clean it again if necessary the next day.
