What cleaning products should I avoid using on the washing machine?

Do not use abrasive powders or cleaning pads on the exterior. For the interior, do not use benzene, thinners, cleanser, or wax, nor scrub the washing machine with a brush as painted surfaces or plastic parts will be damaged. Also, do not spray water directly on the parts of the washer as it may shorten its lifespan and cause electric shock or fire hazards.
