When the set gets dirty, wipe it with a soft, dry cloth.

Never use alcohol, thinner, benzene, insecticide or other volatile agents, for they may damage the surface paint or gloss

of the set.

Also do not wipe the set with a chemical cloth or leave it on the set for a long period, for the surface finish may

deteriorate or the paint may be stripped off.
