Lubricating Black & Grey Valve Slides

Mine are getting "sticky". What have you found that is best for lubricating these guys?

Every couple months when I'm doing a dump, I give the valve stems a squirt of TriFlow.

Its a teflon based lubricant.

There was a great tip in Trailer Life mag this month.
A picture would be worth a 1000 words but that would be copyright infringement.....

In a nut shell -- close the valve and drill a tiny hole in the back end of
the valve body near to where the valve stem comes out- like an inch away
from the stem. Then put the capillary tube of a can of spray lube in the hole and
spray away. He then sealed the hole with a tiny screw until the next time.
Supposed to last several months or dumps.
He was using white lithium spray grease but I think silicone spray would work
fine too.

Wow, Kydan why didn't I think of that. I am going out with the drill momentarily, after finding the article.
I yearly take a very long Q-tip dipped in O-ring lube and slather the inside of the gate valve but it only last about 10 dumps and then gets sticky again.
Thanks for posting; always find new ideas out here.
