Everything you need to know about why lubricant keeps drying out: causes and how to fix it, explained plainly.
Work through these in order, the most common causes come first.
Wrong lubricant for the application: penetrating oils have a high evaporation rate.
They penetrate corrosion and temporarily lubricate, but evaporate over days to weeks.
If reapplication is frequent, this is almost always the issue.
Lubricant washing out: exterior applications expose lubricant to ra in and temperature cycling.
White lithium grease or chassis grease resists water and stays in place through weather cycles.
Clean first: remove old lubricant and accumulated debris before applying new lubricant.
A rag or brush removes most contamination.
Switch to the right lubricant: white lithium grease for hinges, locks, and tracks.
Chassis grease for automotive ball joints and suspension.
Dry PTFE for dust-prone surfaces.

FAQ
WD-40 original is a light petroleum distillate, very thin, with a high evaporation rate. It provides short-term lubrication but evaporates faster than grease or machine oil. The residue it leaves behind also attracts dust, which creates friction. For lasting hinge lubrication, use white lithium grease instead.
White lithium grease on interior hinges: 1-3 years under normal use. Machine oil on locks: 6-18 months. Dry PTFE spray on drawer slides: 6-12 months. Chassis grease on ball joints: typically replaced at each oil change interval (6-12 months). High-temperature or high-load applications accelerate lubricant breakdown.
