VpCI®-423 is a water-based gel that effectively removes rust and oxides from steel, iron, brass, and copper. When used as recommended, VpCI®-423 will not adversely affect most paints, plastics, wood, textiles, ceramics, or rubber. VpCI®-423 is formulated to cling on vertical and overhead surfaces for rust and oxide removal in difficult-to-reach spaces. VpCI®-423 contains flash corrosion inhibitors to prevent flash corrosion during the rust and oxide removal process. After rust removal, rinse the area thoroughly with water, then use Cortec® VpCI®-414 or similar alkaline cleaners to ensure a clean, corrosion free metal surface. VpCI®-423 is NSF (A3) registered, acceptable for use for indirect food contact. It contains 91% USDA certified biobased content and qualifies for Mandatory Federal Purchasing in the USDA BioPreferred®
