First, you have to define the REAL problem, then you can solve it.

Cheap imported aluminum base lamps and cheap aluminum shell sockets
are always bad separately, but when they are combined and you add any
moisture at all and allow time for them to corrode to each other...

Buy the better brass or nickel plated brass based lamps, and brass
shell sockets. Then they'll come apart without a big fight.

I've been having great luck with a little tube of spark-plug-wire goop
from the autoparts store.

Dielectric grease, that's it.

That works... There's also Ideal "Noalox" compound that is made for
electrical connections.

But most people don't have the presence of mind, or the materials on
hand, to goop up every lightbulb base as they replace burnt out lamps.
Installing better fixture sockets and buying better bulbs is the
proper long-term solution.
