DO NOT BUY THAT CARLUBE STUFF!!!
I bought some and threw it away as it is garbage.
I also bought
these (after throwing the Craplube stuff). Good quality silicon grease that I have used on military aircraft for years.
The MS494 will do a very good job on the contacts.
Could try
Servisol as well.
I also use Contralube 770 but it is getting harder to find and is very expensive.
