How can I remove brass marks from my gun's blued finish?

To remove brass blemishes from blued steel firearms, use a Birchwood Casey Presto Gun Blue Pen. Apply the pen's felt tip directly to the mark; the compound dissolves the brass residue. Wipe clean with a cloth afterward. This method is effective for blued steel and nitride finishes.

What causes brass blemishes on firearms?

Brass blemishes on firearms typically occur when using brass punches for maintenance tasks like moving sights or removing pins. The softer brass can leave residue on harder steel surfaces, creating visible marks that can be difficult to remove with standard cleaning methods.

Are there any preventative measures for brass marks when working on gun sights?

Yes, to prevent brass marks when adjusting sights, modify your brass punch. Use a file to flatten the rounded end of the punch, creating a more stable, flat surface area. This provides better contact with the sight and reduces the likelihood of the punch slipping and marring the finish.

What types of firearm finishes are suitable for the Presto Gun Blue Pen method?

The Birchwood Casey Presto Gun Blue Pen is primarily recommended for blued steel and nitride-coated slides. While it effectively removes brass, it's advised to use caution on other finishes like Cerakote or baked-on coatings, as the compound might interact with them or cause physical damage.
