Trisol in a 100 ml bottle, a firearm-care product for the gun safe and the cleaning kit. We could not confirm the exact formulation of Trisol online. It is sold in the same firearm-care range as RAM Gun Oil and RAM Nitro-Solvent, and the name points to a multi-purpose (clean, lubricate, protect) gun-care product; please read the label for directions. The liquid can be applied with a patch, cloth or brush, or a few drops at a time on moving parts. After use wipe off the excess, as a thin film is all that is needed, and keep the bottle closed and away from children.
