LOL, troll calling others troll... too funny. Someone should really send Dave a link so he can warn this guy again. Nice try with the baiting BTW...more trollish behavior.
I am watching the topic and will review it later, I'm currently out trying to raise money for charity.

In a nutshell, when cleaning the Wiper PCB tracks should a lubricant be applied afterwords or not ?
yes - unless you want to wear the gold/carbon plating off.
The type of lubricant & the lubricant base are like debating religious values. 100's of different formulas.
stj, I looked into
lithium grease and it was the usual mess of opinions:
"...lithium is an alkali metal and it conducts electricity"
"...lithium chloride is a solid, it does not contain free moving ions to conduct electricity. It only conducts when it is in the molten or aqueous state"
I find companies selling it for use in switches and HV switchgear etc.
Lubriplate lithium greaseI have no idea if leakage current is a problem with metal-salt lubes like lithium and molybdenum.
You spend $500 on a DMM and probably want to use the right stuff.

Warn me for what Kretzi ?
injecting a bit of humor here and there, the 87V Affair, suggesting alternative 'working' methods to get stuff done...?
Lighten up mate
You got kicked OUT of the 87V thread by Dave, if you keep it up you'll probably be kicked out of this one as well.

Basically it's best to use the same stuff that was there before the cleaning,
if it's not in a service manual what to use, email the company's support and find out
If the original stuff was attracting dust or became hardened sticky sludge in a short time, get a better product recommended for wiper pcb tracks.
i.e. don't leave it clean and bare if there was lube there to begin with, otherwise it's metal to metal friction you don't need = $$$

That is the best thing you have said so far. I agree.
For sliding contacts like the ones in a DMM switch, consider using polyphenylether based lubricant. It stays wet but doesn't attract much dust, and forms a very thin layer that won't raise the contact resistance. MG Chemicals and Techspray make them.
Obviously this is not suitable for any surface that experiences mechanical loading, like the spring and ball bearing in the switch assembly. The proper lubricant for those is silicone grease.
I recently got some lubriplate for my antenna tuner and I got it in 3 small (1/4 fl oz) tubes sold as genie screw drive garage door lubricant. Its enough to last me a very long time. I forget what it cost but it was only a few dollars. It seems to help, I'm still learning how it works, how much to use, and need to do some more experimenting with it. Would be happy to test it in any way you can come up with. Very sparing application seems to be best.
