ABSTRACT A process for making a replaceable part of a sponge mop normally referred to as a refill. The refill is made by enclosing the sponge in a mold and compressing it to close the pores of the sponge on at least one side. A thermoplastic material in the molten state is then injected into the mold against at least one surface of the sponge and allowed to cool. The sponge is then removed from the mold, and water is applied to it to expand it to its original condition.
