Abstract
A method for cleaning a plastic's surface so as to effect removing metallic particulate contaminants from the plastic's surface, including rinsing the plastic's surface with electrolyzed water, anodic water, cathodic water, or ozone, so as to remove positive charges left on the plastic's surface by the anodic water, and then rinsing the plastic's surface with deionized water; wherein the rinsing of the plastic's surface with the electrolyzed water, anodic water, cathodic water, or ozone, and then the deionized water effects cleansing of the plastic's surface to a predetermined cleanliness value.

A method for cleaning a plastic's surface so as to effect removing metallic particulate contaminants from the plastic's surface, comprising:
- rinsing the plastic's surface with electrolyzed water, anodic water, cathodic water, or ozone, so as to remove positive charges left on the plastic's surface by the anodic water, and then
- rinsing the plastic's surface with deionized water;
- wherein the rinsing of the plastic's surface with the electrolyzed water, anodic water, cathodic water, or ozone, and then the deionized water effects cleansing of the plastic's surface to a predetermined cleanliness value.
An apparatus for cleansing of a plastic's surface to a predetermined cleanliness value, wherein the apparatus comprises:
- an electrolysis cell having a chamber with an ion exchange membrane disposed therein,
- a mixing tank coupled to the chamber, the mixing tank configured to receive deionized water via a supply line for mixing with one of an anolyte and a catholyte;
- a chamber feed communicably coupling the mixing tank and the chamber, the chamber feed configured to deliver the one of an anolyte and a catholyte mixed with deionized water into the chamber;
- and
- a common plastic's surface cleaning applicator coupled to the chamber and the supply line, the applicator configured to effect rinsing the plastic's surface with electrolyzed water, anodic water, cathodic water, or ozone, so as to remove positive charges left on the plastic's surface by the anodic water, and then rinsing the plastic's surface with deionized water;
- wherein the rinsing of the plastic's surface with the electrolyzed water, anodic water, cathodic water, or ozone, and then the deionized water effects cleansing of the plastic's surface to a predetermined cleanliness value so as to effect removing metallic particulate contaminants from the plastic's surface.
