MPN: 32 OZ OXPHO
Oxpho-Blue is a cold bluing solution built for restoring and touching up the finish on steel firearms and tools. This 32 oz size suits shooters, gunsmiths, and anyone keeping a stable of guns in shooting condition without sending parts out for hot-tank work. It lays down a durable blue-black finish with no heating required, which makes it practical at the bench or in the field. The solution earned its reputation among professional gunsmiths because it applies easily and holds up, unlike many cold blues that fade or rub off. If you maintain blued steel, this is a staple worth keeping on the shelf with your other bluing chemicals.
The formula works by bluing the underlying steel as it goes, and it removes light surface rust during the same application. That dual action makes it useful for repairing worn edges, holster wear, and small scratches without stripping the entire part. Application is straightforward with cotton flannel, and once cured the finish resists subsequent rust formation. It is formulated for steel and is safe to use around polymer frames, so a slip onto a polymer-framed pistol won't ruin the part. Note that it is not intended for stainless steel or anodized aluminum, since those surfaces won't take the chemical reaction the same way. The 32 oz volume covers repeated touch-up work or a full refinish on a long gun barrel and action.
Reach for Oxpho-Blue when a carry gun shows holster wear, when a hunting rifle picks up scratches in the field, or when an older blued firearm needs its finish brought back. Clean and degrease the steel first for the best result, then apply, let it work, and wipe down. Follow up with a protective coat of oil to lock in the finish and keep moisture out. Pair it with quality gun oil and the right brushes to round out a complete refinishing setup. For smaller jobs, we also stock the cream version in a 4 oz size.
No. Oxpho-Blue is a cold bluing solution, so it works at room temperature with no torch, tank, or heat source. You apply it with cotton flannel, let it react with the steel, then wipe down and oil the part. That makes it practical for bench work and field repairs alike.
No. The chemistry is formulated for carbon steel and won't react properly with stainless steel or anodized aluminum. It is safe to use around polymer frames, so an accidental drip on a polymer-framed pistol won't damage the part.
Yes. Oxpho-Blue removes light surface rust as it blues the underlying steel, so it handles touch-ups and minor rust repair in one step. Heavier rust should be addressed mechanically before application for an even finish.
The 32 oz size is the largest standard volume and supports repeated touch-up work or a full refinish on a long gun barrel and action. For occasional small jobs like edge wear, the 4 oz cream version may be a better fit.
Wipe the part down once the finish develops, then apply a protective coat of oil to seal the surface and keep moisture out. A quality gun oil locks in the blue and helps prevent subsequent rust formation.
