Abstract

A decontaminating system (200) is provided that includes: (a) a decontaminating apparatus (100) including (i) an electrically conductive scrubbing shoe (104) having an inlet (204) for a gel-like material and (ii) an insulating standoff (116) positioned between the scrubbing shoe (104) and a surface (120) to be decontaminated to maintain a desired distance between the scrubbing shoe (104) and the surface (120); (b) a reservoir (216) for the gel-like material (124), the reservoir (216) being in communication with the inlet (204); and (c) a voltage source (224) in communication with the electrically conductive scrubbing shoe (104), whereby a current is passed through the gel-like material (124) applied to the surface (120), thereby removing contaminants from the surface (120).
