Not trying to step on toes, but I'm confused.
Lithium grease will work for any point which is not in the electrical circuit path. If you are lubricating the sliding contacts themselves, or any other part of a current path, do not use lithium grease. It is not a conductive medium and will create a high resistance connection. The contacts can overheat and fail. Dielectric grease, which is formulated to be an electrical insulator, will produce similar results. Both types of grease are made to prevent electrical current from passing. There are "conductive" greases that have high carbon (graphite).
Again not trying to step on toes but 23 years as an electrician and I've seen several contacts fail because the current is trying to arc past the grease.

If you like it and it works I'm not telling you to stop
