Assembly for cleaning toner resin from a printing device and method

An assembly is provided for cleaning toner resin from the operating parts of a printing device. The assembly comprises a porous member impregnated with a silicone copolymer and a rigid member with a supporting base to mount said porous member. The assembly is preferably a two-part kit having a brush member for wiping components of the printing device and a pad member mountable for stationary positioning within said printing device for scrubbing components of the printing device as they move relative to the mounted pad. The silicone copolymer has the formula ##STR1## where x represents from about 98.8 molar percent to about 99.5 molar percent, y represents from about 0.5 molar percent to 1.2 molar percent and R comprises from about 70% by weight to about 100% by weight of a C.sub.15 -C.sub.60 alkyl group and from about 0% by weight to about 30% by weight of a C.sub.2 -C.sub.14 alkyl group.

Method of cleaning toner resin from a printing device

A polyol polyester and hexamethylene diisocyanate in a fluid mixture with white pigment, silicon glycol surfactant and thinner are pad printed on keyboard key to print characters and symbols which require no protective overcoat.
