Otis Technology O85 Ultra Bore Solvent does more than just clean the inner workings of your firearm. Yes, this cleaning tool is exceptionally good at freeing carbon, dirt, and gunpowder residue from the metal surfaces of your weapon, but it also goes the extra mile to protect your firearm from further harm. Apply the Otis Ultra Bore Cleaning Solvent to your cleaning patch of choice to create a thin film that prevents rust and corrosion from getting a foothold. What's more, this Otis cleaning tool also functions as a lubricant, sealing out moisture and reducing surface friction in all the tight spaces of your gun where it penetrates. Otis Technology packages this magic fluid in many of its most popular cleaning kits since it works so well, but you can buy the cleaning solvent individually in either a 0.5 ounce tube or a 2 ounce bottle. For a multi-function cleaning agent that penetrates, protects, and lubricates your firearm of choice, soak your next patch in the Otis Tech O85 Ultra Bore Protective Cleaning Solvent.
