3-IN-ONE Lock Dry Lube is an aerosol formula that penetrates quickly and deeply to dissolve build-up and lubricate lock mechanisms. Leaves a clear, dry, long-lasting, corrosion-protecting film that will not attract dirt or create a mess. Graphite-free, 3-IN-ONE Lock Dry Lube is ideal for automotive, marine, home, and commercial locks and padlocks, and is safe to use on metal, wood, and most plastic surfaces (except clear polycarbonate and polystyrene). With the attachable straw, easily reach into any narrow lock mechanism, and with the wider spray pattern, refurbish and protect the entire lock. Quickly and easily unstick any lock and prevent it from sticking again.
