Over time, your floor pump’s pressure gauge can start to deteriorate, making it less accurate. “If using a liquid silicone lubricant, a good spray on the pump shaft, and then pump up and down a few times to get the lube to get everywhere in the pump.” Pressure Gauge Apply a little bit of grease to the plunger and reassemble,” Nankman says. “If using grease, you need to take the top cap off the pump to expose the plunger.

I, too, am guilty of chucking my bike pump in the car and leaving it there, well, indefinitely. Store your floor pump somewhere out of the elements and away from moisture that could potentially damage it.
