HWH says to spray with WD-40 and wipe off.
Since there seems to be so many answers about HWH. Read this link. This FAQ is from 8 years ago and HWH does not really recommend WD 40 or silicone anymore. The Sticking jack referenced was from 8 years ago and at that time HWH thought using WD 40 or silicone would possibly fix the sticking jack problem. It did NOT, as it was defective seals and they changed the seal design about 5 years ago. As I stated, cycling the jacks twice a month will be all that is needed unless they get extremely dirty. When retracted, they are immersed in ATF fluid which means you do not have to lube with WD 40 or silicone. Doug
