Komar 8-256 Use and Care Manual

 Do not use abrasive cleaners such as bleach or as
steel wool, as this could damage and discolor the wall
mural.
 When cleaning, begin at the bottom and work
upward. This prevents dirty water running down the
mural. Use a slightly damp sponge or brush. Do not
saturate the wall mural.
 After cleaning with the mild, soapy water, wipe the
mural with a damp, clean sponge, and blot dry with a
soft, lint-free cloth. Remember to wipe in the
direction of the seams, which are usually vertical.
