Automotive professionals know how years of built-up rust can negatively impact an engine, and how much of a hassle it is to remove it without the right product. Not having the right product will not only cost you money, but it will also cost you time – especially when trying to wrench stuck fasteners by hand. To make removing stuck fasteners and rusted on bolts easier, use WD-40 Specialist Penetrant with EZ-REACH.
WD-40 Specialist Penetrant with EZ-REACH is a fast-acting penetrant that breaks through corrosion and rust and penetrates up to 2x faster than the competition*. The penetrant has low surface tension, which generates capillary action. This means it will penetrate the tightest spaces of a fastener, even creeping upwards in defiance of gravity to reach tiny cracks and gaps to reduce friction between threaded surfaces.
Wrenching stuck fasteners by hand will cost you more time – and you have the chance of stripping, stretching or breaking the threads, which costs you money to remove and replace a broken piece. Taking a little time to spray down a fastener with WD-40 Specialist Penetrant with EZ-REACH can lower the potential of damaging a fastener by decreasing the friction and can save you time and money by not having to disassemble equipment, since the flexible straw can bend to reach tough fasteners.
If you like WD-40 Specialist Penetrant with EZ-REACH, you can learn about the entire product line of superior performance, specialty products – lubricants, greases, cleaner and degreasers, and rust management solutions – specifically designed for the world’s toughest jobs at
