More in hope than faith, I put some WD-40 equivalent on E14 threads of new lamps. There's no significant temperature as they're 3W, 320 lm, LEDs mounted horizontally. In about 10 years' time...
Heard of silicone grease being used on GES lamp sockets outdoors, but GU10 Twist And Lock , TAL as it was when it came out, is just a crap socket.
And the bulb is clean. Old bulbs might well have a coating of something slippery. Even just dust.
Certainly will in a kitchen, especially if ghee has been used. I had to clean a ghee-coated kitchen once - didn't know about AGs then!
If you want grease, conductive grease is the last thing it needs. Most greases become corrosive in the presence of electricity.
