I've had screws work loose on revolvers of any vintage and several manufacturers. S&W was putting a thick, orange locking substance on the yoke retention screw in the 90's. Seems like they don't use it anymore. Just put a dab of blue thread lock or clear nail polish on the threads and your problem is solved.
I've basically stopped using the modern version of Hoppes' No. 9, as it does not clean well compared to newer solvents.
Hoppes Elite/M-7 Pro work very well and do not harm modern gun finishes. Kano Kroil is great for getting lead out- it works under and big strips will just pop loose with a very tight patch.
