Trisol in a 120 ml aerosol can, 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 aerosol reaches into actions, triggers and other places a cloth cannot, and helps flush out dirt and old oil. After use wipe off the excess, as a thin film is all that is needed, and keep the can away from heat and do not puncture it.
