Use a steam cleaner to get rid of stains and unwanted growth like cigarette stains, mold, bedbug and cockroach eggs, and fly spots on your wall, ceiling, and sometimes, the floor. Steam cleaners use the extreme temperature to kill the mold spores and insects eggs and larvae that are causing unpleasant damage to the wall. This process is all-natural and it is highly effective.
Using a duster or wipe remove as much loose dirt as you can. You can also vacuum it.
Bring out your steam cleaner, fill it with water, attach the extension hose and cleaning head.
Plug it in and turn it on to preheat.
Move the head in vertical moves across the ceiling and walls from one side to another. Always go from top to bottom.
Pay extra attention to tough spots. However, be careful to not over steam the spot to prevent damage. As a rule of thumb, don't let a spot get more than ten seconds of steam.
Do not run the cleaner directly over electric fixtures like bulbs, sockets, fans, and regulators
Let the cleaned part dry.
