Anti-friction Dry PTFE Lubricant is a great lubricating spray for a number of different applications across a huge array of trades & DIY environments. Its anti-friction formula makes it perfect for high-use or repetitive mechanisms that require protection from daily wear & tear, such as door & window tracks, chains & rollers, power tools, drill bits & lock mechanisms. It's ultra quick-drying, & sets as a clear film that won't attract damaging elements like dust, dirt & oil. It also makes an extremely effective mould release agent. As an added indicator of a quality product, WD40's designers have compiled this can with their Smart Straw applicator, which gives you two ways to spray: use the flip-up straw for hard-to-reach areas, such as inside chains, locks or rollers; then flip the straw down to use the wide-angle spray eye for area coverage on larger surfaces. Whichever way you need to spray, you can rely on the clever 360° valve to work efficiently at every angle, even upside down!
