Best lube for grey tank and black tank valves

I've never "lubed" my waste tank valves?? Didn't know that was an option? Going on some 16 years with the same trailer and the valves seal just fine over all those years..

I did have some TP get stuck in the black tank valve so had to remove, clear the TP and reinstall, but that was some 5-6 years ago and no problem since..

How would you "lube" them in the first place??

Not trying to be an Ass... Just have never heard of that before and have never done it before and have never knew there was a need to do it??
