"Wetting" characteristics of the solution, giving it the ability to penetrate oil, dirt, etc., on the surface of the gun; blue the metal underneath; remove rust and dirt; leave the gun blued and ready for oiling. Beauty and high durability of the finish: vigorous rubbing with No. 0 steel wool is one of our favorite application methods - the more rubbing, the more brilliant it comes and, since abrasion is part of the process, normal contact from gun cases, brush and clothing won't wear your bluing. (Note: It is possible to get a surface so dense with Oxpho-Blue that water will puddle on it!)
