FABRIC CLEANER Abstract of the Disclosure An aerosol cartridge is used to supply foam detergent directly to a polyurethane open cell sponge roller having discrete spaced radial cavities open to the outside for receiving the foam and transfer the same to the fabric of upholstery and the like. The cavities constitute working chambers which tend to be compressed as the lands between the same flex and compress in pressure contact with the fabric upon rolling thereover to thereby force the foam through the fabric, and which then suck the foam back through the fabric as the chambers expand on the back side of the roller. The cavities may be in the form of cylindrical holes burned into the sponge whereby the pores at the inner surfaces of the holes are generally closed by a skin effect. -0-
