The corrector can be cleaned easily using a mixture of isopropyl alchohol and distilled water in a very clean dustless room by dabbing with fresh saturated tissue, or Giotto lense cleaner. Do not rub and use up the whole packet , continually changing to a new tissue and fresh mixture for each small section.
Finish with distilled water , dragging the edge of a single dry tissue with no pressure.
Any fungus , sap or dew can be cleaned off first with pure isopropyl alchohol and a paper pure cotton wool swab with a rolling action, but avoid the makers marks if they are faint permanent marker lines on the edge of the corrector.
Wear dust free surgical gloves to avoid prints.
There is a link elsewhere here to a long post on CN and a youtube video showing how this is done.
Others have paint stripped the tube but I wonder if it can be lightly powder blasted inside by your local powder coater, and perhaps they can do the inside only , taping the outside. That would clean it up nicely for a good flat black spray paint.
I would wait until it outgassed and had no smell at all before putting the mirror back. I would only do the inside if possible so the outside can hold your alignment marks.
Others know more about flocking than I do so check the posts. The inside of my 35 yo c8 scope looks perfect , but perhaps it has been repainted inside.
QUOTE=Hemi;1430387]Hi SF,
The primary and secondary mirrors are fine, just a little dust.
The corrector has water marks and Mould.
The aluminum tube has massive amounts of oxidation. The baffle-draw tubes are dusty.
