I just use a mild nonspelling non colored soap and warm water with a sponger and scrub them it works well just dont get the walls soaked. and DONT use vinegar like others are telling you to do it will make your home stink forever!
baby oil works a treat on most things!
vinegar and water will do the trick and they will come realy clean.
