Abstract
A cleaning article used in the absence of a water source, comprises an abrasive substrate and a liquid impregnating it. The substrate is a non-woven abrasive material such as a sheet of plastic fibers and the impregnation liquid is an aqueous solution of d-limonene, surface active agent and hydrophilic solvent with, if desired, the usual additives. Impregnation can be carried out on a stack of towels by pouring the impregnating solution onto the stack, which spreads uniformly throughout the towels.
