Bore cleaning solvent cleans by powerful solvent penetration, without alkaline ingredients. Won't cause corrosion or staining.
The gel version is used primarily inside of long barrels where one would want the solvent to adhere to the inside of the barrel around the entire circumference evenly without dripping down the inside walls of the barrel prematurely.
Safe to use on metals, pH Neutral. Will not cause rust, oxidation, staining, or galvanic corrosion. May be harmful to some paints, varnishes, and plastics. Keep product OFF of these types of surfaces unless a previous patch test has shown no effect. It is recommended that the firearm be re-treated with G96 Gun Treatment, G96 Gun Oil, or G96 Synthetic CLP Gun Oil after use.
