WD-40 Specialist® Dry Lubricant is a non-greasy formula that ensures your equipment and moving parts are working smoothly. It leaves behind a lubricating dry film that resists dirt and dust buildups. Our lubricant delivers superior performance, forming a transparent, non-sticky film that resists dirt and dust. It provides enhanced rust protection. Safe on multiple surfaces including most metals and plastics (*Always test on an inconspicuous area before use). With the Smart Straw applicator, you’ve got two ways to spray – flip up the straw for hard-to-reach areas; flip it down to use the wide angle spray for wider coverage on surfaces.
