Penetrating Spray: What It's For and How to Use It Correctly
What a penetrating spray is
A penetrating spray is a multifunction product combining solvent, lubricant and protective in one formula. Sprayed on rusted bolts, jammed hinges, rusted-in screws, frozen locks, it dissolves incrustations and frees the mechanism. Should always be in any toolbox.
How it works
- Penetration: ultra-low viscosity lets it seep into microns between bolt and nut
- Chemical solvent action: dissolves rust, limescale and grime
- Residual lubrication: leaves film preventing re-jamming
When to use
- Rusted wheel bolts before seasonal tyre change
- Incrusted oil filter or air filter screws
- Squeaky or jammed door hinges
- Slightly incrusted motorcycle chains
- Frozen or rusted locks
- Stuck telescopic antenna
- Hardened fuel cap
- Exposed electrical connectors with oxide
