It's normally meant for pig tail connectors on automobiles where corrosion can not seep in and if it's applied it does an amazing job. Also, when extreme overclocking was kind of cool a few years ago a lot of people used the dielectric grease or in a pinch you could use vaseline.
Personally, I applied this stuff to sockets on computer I keep in long term storage and never had any problems.
If you need to clean the socket you could use electrical contact cleaner. Make sure everything is powered off and PSU disconnected and spritz it in thereand insert/remove the module a few times. Make sure it's evaporated before you power it up again. Shouldn't hurt anything, but it warns you specifically about it on the label. I've personally never ran into an issue.
That's great info. Would like to add, you should always use LINT-FREE cloths for cleaning. I know most people don't mind qtips or baby cotton, but lint is bad and some of that stuff creates static and accumulates build up. Lint-free should be used primarily all the time. For heavy build up on expansion cards, erasers work great for removing build-up and stubborn grime, along with 1 part water 1 part alcohol to finish cleaning. Pure alcohol works but it can be too dry IMO.
