HWH says to spray with WD-40 and wipe off.
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

What will cycling do to help the seals?
Unless the seals are shot the fluid is contained by them, I.E. the wet side is always wet and the dry side is always dry.
It would seem cycling would just expose the wiper seals to that much more debris.
If the MH is moved 4 times a year the wiper seals are used to clean the piston rod of debris 4 times. If the jacks are cycled twice a month the wiper seal is used to clean debris 24 times a year.
