"Maintenance of Carabiners
Keep carabiners dry and clean. Protect carabiners from corrosion. Do not store in humid or salty air, with damp clothing, or near corrosive chemicals. Do not file, engrave, etch or modify carabiners for any reason. Sand any burrs with 220-400 grade sandpaper. If this does not remove the burr, destroy the carabiner.

If a carabiner gate sticks, use an air hose to blow grit out of the mechanism, wash it in warm, soapy water, rinse thoroughly and lubricate with dry graphite around the hinge area, inside the spring hole and locking mechanism. Perform the 3 step inspection process outlined below before each use. Please remember that some environmental effects such as salt water can shorten the life of your carabiner and cause premature failure."
