Cheers @chickendrumsticks I'll give that a readhttps://www.photo.net/forums/topic/287149-shutter-lubrication/
Some good (old) info here. In the past my old dad (a keen amateur) swore by lighter fuel carefully applied by cotton bud. Definitely don't use any lubrication on blades themselves. It will always leave a residue.

I've just given it another look (taken film out & furiously wound on & shot for 10 mins) & it seems to only stick when on auto aperture. so I can at least continue to use it manually
