I'm having my first go at cleaning the shutter from my Agfa Record lll by soaking and rinsing with Ronsonol. I've gone through the process twice and removed a fair bit of debris but when it dries off the blades of the shutter and aperture have a lot of marks on them similar to water stains. They went away when soaked the second time but now a new set of them have appeared. I this anything to be concerned about? |

Usually not - but I wonder where the stains come from??? I never had this problem when cleaning shutter or aperture blades (and for some time I used Ronsonol, too). Maybe you should wipe the blades more carefully and use a new tissue or an unused part for it for each blade. |

Thanks Winfried. I hadn't been wiping them for fear of getting lint fibres on them - just letting them air dry. That could be the problem because quite a bit of fluid sits on them during the drying process. One more try! |

Yes, most paper tissues leave some tiny fibres on the blades but it is no problem to blow or brush them away. |

A small contribution.
You can polish such blades with a cotton-bud which has been touched with graphite powder. The blades will come up beautifully - and it helps for smooth operation too.
You only need a VERY SMALL amount of graphite - and you should blow clean afterwards otherwise any residual graphite particles may find a home on the surfaces of the optics and manifest as little sparklers. This procedure has always worked fine for me on literally hundreds of shutters - and I never had a problem.
You won't get cotton-bud fibres jammed if you stroke "away" fron the leaf overlaps. If you use tissue you will spend forever trying to remove little specks.
Hope this helps |

Problem solved. I merely had to spend a few minutes just touching the blades with tissue until no more fluid appeared and they stayed clear. I found some great stuff for doing temporary fixes on the bellows on this camera but will do a separate posting with it. Thanks for your input gents. |
