Corrosion on camera bodies

[BrianSummers]

As some of you may know I have a modest collection of ex broadcast TV cameras as part of the collection at www.tvcameramuseum.org

Some of the cameras, those with the lightweight aluminium/magnesium castings, have corrosion of exposed corners and around fittings. It is that white gooey type, rather like what you see on some discharged batteries, often wet to the touch, but the camera is in good storage and in the dry.

My question is how can I minimise this and/or fix it. I don't want to paint the cameras as this would remove originality or to smear with silicon/Vaseline/oil as these would be sure to migrate to the optics causing damage there.

Has anyone any good suggestions?

The camera pictured is a Philips LDK14 in it's flight case, the picture was taken a couple of years ago and it has deteriorated somewhat since, hence this posting.
