Abstract
A synthetic sponge having a high density is rinsed while changing the hydrostatic pressure of rinsing solution in pore spaces of the sponge to remove chemical residue and particulate matter more completely. The hydrostatic pressure can be changed by varying fluid supply pressure or varying centrifugal force. A rinsing apparatus includes a rotatable container and a fluid supply for supplying rinsing solution to sponge material in the container.
