I think I've usually just used Phil Wood grease, a specialty bicycle grease, 
but any light grease is probably fine. 

The TVSs die when the sliding contacts wear into the G-10 fiberglass PC 
board material. The major wear actually does not occur to the gold PC board 
plating. When the PC board is pitted deeply enough that the sliding contact 
can now touch 2 adjacent gold contacts, the FI will no longer work right when 
the throttle is in this position.

Late replacement TVSs, came with what appears to be a kind of green teflon 
overlay on top of the fiberglass board and under the gold contacts. I suspect 
that these last "forever" but that's a bit hard to test. ;-)
