Cleaning Hardboard Panels
Hardboard panels, often made to look like wood or
other materials, have a baked-on plastic coating which
can be washed with detergent solutions and rinsed like
painted walls. If very dirty, use a stronger solution,
testing first in a hidden spot to be sure it doesn't
damage the finish; or use a commercial household cleaner
whose label says it's safe for painted walls, and rinse
thoroughly. Do not use solvent on hardboard or
particleboard panels, as it may damage the surface.
