PCC Mold Blaster 1000 is a peroxide based cleaner that reacts with organic matter and generates the release of Oxygen. This reaction will lift organic stains and other contamination from deep within the treated surface of porous material allowing ease of removal later. This literally boils out the vacuuming with HEPA filtered vacuum equipment. PCC Mold Blaster 1000 also contains surface active agents to enhance wetting and allows for deeper penetration into the substrate of wood and other porous materials. PCC Mold Blaster 1000 is 100% organic and biodegradable.
