Penetrating oil from Grainger helps remove sticky or adhesive residue and loosen rusted hardware. Low-viscosity penetrating fluids can flow into narrow spaces between bolt threads and stuck metal parts. Lubricant sprays can remove grease, grime and tar while helping displace corrosion-inducing moisture. For higher performance under high-temperature conditions or heavy loads, choose a lithium grease-based penetrating oil such as PTFE spray or molybdenum compounds. Find them at Grainger!
