Abstract: A firearm bore cleaning agent and method are provided for detaching fouling residue from a bore of a firearm. The fouling residue includes carbon and metal residue, such as copper and lead, and the carbon residue acts to bond the metal residue to the bore. The firearm cleaning agent comprises the combination of a hydrocarbon solvent, such as butyl or amyl lactate, and an electrical neutralizing agent, such as hydrocarbon citrus distillate. The hydrocarbon solvent is configured to detach the metal residue from the bore by dissolving the carbon residue and the electrical neutralizing agent is configured to bond with positive ions of the metal residue to prevent the metal residue from rebonding to the bore.

Abstract: A composition containing an antimicrobial and a silicone-based emulsion is disclosed for treating heat exchange surfaces. The liquid formulation retards microbial growth and prevents debris from adhering to the surfaces, thus minimizing fouling. The composition does not form a film on the treated surfaces, but rather clings via ionic interaction; thus the heat transfer characteristics of the system are not substantially altered. In addition, the composition does not contain any volatile organic compounds, which can be harmful to a building's occupants. An application method is further disclosed that entails spraying the composition into the cooling coils to be treated, drawing the composition across the heat exchange surfaces in an air stream, and drying the surfaces. This method results in the formation of a low-friction antimicrobial deposit that will resist fouling and microbial growth.
