OTIS O85 CLP 4OZ

Description

Otis O85 CLP is a three-in-one solvent, lubricant, and protectant built for shooters who want a single product that handles the full cleaning cycle without switching between bottles. The formula has been in continuous use for over 40 years, which gives it a long track record across a wide range of platforms and conditions.

What sets a true CLP apart from a dedicated solvent or oil is the compromise it strikes at every step: it dissolves carbon, powder residue, and metal fouling while simultaneously leaving behind enough of a lubricating film to reduce friction between moving parts. O85 is engineered to work into tight clearances — think bolt carrier groups, trigger components, and barrel extensions — where a thicker oil would pool rather than penetrate. Once the solvent fraction does its work, the residual film bonds to the metal and seals it against moisture, which is the primary driver of rust and pitting in stored or hard-used firearms.

For bore cleaning, the process is straightforward: apply O85 to a patch or brush, work through the bore to loosen fouling, then follow with a dry patch to remove the excess. The same approach covers external metal surfaces, frame rails, and any other area you’d normally treat with a separate protectant. The 4 oz. tin format is practical for a range bag or cleaning station — enough volume to last through multiple cleaning sessions without being cumbersome to carry.

This is a practical, no-frills choice for a shooter who values consolidation and a formula with a demonstrable service history over novelty.
