Just clean the sliders with q-tips and add petroleum jelly?
Or is there a special grease?
Or do you tear apart the drain valve first?
Or doesn't Thetford have something that you just pour in the tank? How does that work?
Thanks in advance for any advice.

NEVER EVER use petroleum jelly on rubber seals. It will most certainly destroy the rubber in a very short time. Hardware stores sell a little tin/can/jar of “plumbers Silicone grease” which is designed for moving parts in faucets and valves. It cost about $ 2-3 and will last for a long time. But you will have to apply it by smearing it into the grove the valve slides in.
Another method is using a spray can of liquid silicone spray. May not last as long as the grease but it is easily applied with the valve open.
Good luck with it.
