A method for rinsing a synthetic sponge material, the synthetic sponge material being formed through a process which leaves residue or particulate matter in pores of the synthetic sponge material, the method includes the steps of:a) contacting a rinsing solution with the synthetic sponge material; b) centrifuging the sponge material containing the rinsing solution; c) changing the hydrostatic pressure of the rinsing solution during said centrifuging step to expand and relax the pores of the synthetic sponge material to effectively pump the rinsing solution into and out of the pores, wherein the residue or the particulate matter in the pores of the synthetic sponge material are removed. The hydrostatic pressure can be changed by varying fluid supply pressure or varying centrifugal force.
