Quick Tip: Tricks To Apply Cold Blue

Hey, Steve from Brownells here. Today we want to revisit cold bluing, covering some tricks and tips to make the job easier. Let’s take a look at how to deal with surface imperfections without fully disassembling or hot bluing your gun for a quick fix.

1. PREP THE SURFACE: Start with a clean surface. Use rubbing alcohol to clean off any oil or gunk.
2. USE OXPHO BLUE: We recommend Oxpho Blue. Pour a little into a separate container to avoid contaminating the solution in the bottle. Apply it to the cleaned surface.
3. APPLICATION TIPS: If you're not getting a good color, try warming the steel or using 4-0 steel wool as an applicator.
4. TRY DIFFERENT COLD BLUES: If one type of cold blue doesn’t work, try another until you find one that does.
5. BURNISH IF NECESSARY: Sometimes, burnishing and reapplying can enhance the color.
6. WIPE DOWN WITH WATER: After achieving the desired finish, wipe down with water to dilute and remove any residues of the cold blue to prevent after rust.
7. OIL IT UP: Finally, spray it down with some oil, rub it in, and you've got a decent finish.

Remember, cold bluing might not get you a factory-type finish, but with patience and multiple applications, you can get close. Practice on mild steel like a 22 barrel for the best results.
