Head to your local auto supply place and get some of te dielectric
grease(white sff in a smal tube or a vinyl pouch) that is used for spark
plug boots and bulb connections in cars. One tube will last you forever,
its a good lubricant and conductor.

Remember that WD 40 is essentially kerosene with perfumes. Eventually it
will gum up, attract dirt and dust, and possibly interfere with good
electrical contact.

I have some horizontal flourescent light fixtures that have sockets to
accept horizontal bulbs with 2 pins at each end. in trying to replace
the bulbs, the bulb pins are stuck in the sockets.

would it be useful, and also safe, to spray wd-40 into the sockets
before inserting the bulbs?

best, Aaron
