1. A method for packaging a porous polymeric member in a containment package, the method comprising:
- providing a porous polymeric members the member comprising an outer surface and a plurality of impurities distributed through the member;
subjecting the porous polymeric member to a wash cycle, the wash cycle comprising at least two sequential and different treatments selected from the group of an acid treatment, a base treatment, or a solvent treatment;
providing a containment package; and
positioning the porous polymeric member within the containment package;
wherein the porous polymeric member comprises a shape selected from the group consisting of a brush, a puck, a pad, or a plug.

Abstract
The present invention provides a novel method (400) for packaging sponge or porous polymeric devices, e.g., scrubbing brush. The method includes a step of providing a porous polymeric member (401), which has an outer surface and may also include inner surfaces. The member is substantially free from impurities (e.g., ions, particles) that may be distributed on the surface and through the member. Preferably, the method treats the devices using a preservative to prevent bacteria growth during storage or shipping of the devices. The brushes are removed from the wash treatment and placed within containment packages.

17. A method for packaging a porous polymeric member in a containment package, the method comprising:
-
providing a porous polymeric member, the member comprising an outer surface and a plurality of impurities distributed through the member, said impurities less than about 0.20 parts per million;
subjecting said porous polymeric member to a preservative, said preservative preventing microorganisms from growing on surfaces of said porous polymeric member;
positioning the porous polymeric member within a containment package while in a cleanroom environment; and
sealing said containment package in the cleanroom environment.- View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
