When I installed my Sanwa JLWs, I lubed them up with some white lightning lithium grease ( or something like that ) from Home Depot.
Well the sticks have been a little sticky lately where they seem to be hanging up.
Last night the right one was getting real annoying.
The grease had gotten like congealed and rubbery.
Of course it was in the middle of a game night with my son.
So now I took out one stick last night (they're a little tough to get to) and cleaned all of the grease out. Much better.
I guess I will get the lube that I've seen Randy recommend in another thread
