Dry lubricant spray dries quickly, leaving behind a powdery coating that reduces friction. It can also withstand extreme high and low temperatures that would cause other liquids to freeze or degrade. Dry lubricants resist grime, don’t displace water and can be used in dusty environments where oily residue or mud might create problems. These sprays can be applied on most metals, wood and plastic surfaces indoors or out. They’re useful for door hinges and locks, drawer slides, toolbox drawers, drywall fasteners, woodworking equipment, synthetic cord, twine, rope, and machine parts.

Dry graphite lubricants are popular choices for reducing friction on equipment. They can also be sprayed onto metal components, including bolts and threads, to prevent corrosion and increase their longevity. Unlike some other lubricants, these graphite sprays and powders don’t attract dirt or dust. However, they’re not as good at freeing stuck parts as penetrating lubricants and require more patience.

Other common dry lubricants include sprays that dispense a powdery coating of molybdenum disulfide and those that contain boron, which dries clear for easy visibility. These lubricants are suitable for use in dry, dusty environments and can be used in place of oil in some applications. They may need to be reapplied more frequently than some other lubricants, but they don’t leave an oily mess and won’t attract dirt or grime like grease can.

Lock dry lubricants loosen frozen or corroded lock mechanisms and lubricate the mechanism to ease sliding motion and reduce squeaking. They also protect the locking mechanism from further damage and corrosion. These sprays and powdery substances are also great for reducing friction on garage doors and rolling door tracks, window guides, and wire rope.
