Clean and degrease the metal thoroughly before applying cold blue, and test on a hidden area first.

Prepare surfaces carefully and follow the label instructions for the best result.

Use in a well-ventilated area and keep away from children.

Regular cleaning removes fouling and moisture that cause rust and loss of accuracy. Make sure the firearm is unloaded before cleaning, work in a well-ventilated area, and store cleaned firearms in a dry safe with a light protective coat of oil.
