Just drip engine oil with a tooth pick, used chopsticks or used bamboo fruit spears. No need buy expensive spray lube. I used same method for padlocks, hinges, car key hole, PC chassis fan and even my table fan. I just need good quality oil to be in those area. Spray are convenient. But the oil inside just isn't as good as engine oil. I also have a drip bottle filled with engine oil ready to use anytime something needs to be lubed.
