Getting ready to restore some old Heathkit Tube Amps, thanks for your info...these old things have been out in a garage forever and are filthy. And yes, I know to discharge the filter caps before doing ANYTHING! :)
Great info! I always wondered how to remove rust without sanding. I'll try this technique on my Zenith 7K31 amp chassis. One recommendation I have, is to try some De-Oxit D100 or Faderlube for the potentiometers and switches. They are specifically made for that.
It does do a pretty good job as a rust inhibitor. For example check out this test Brownells conducted: www.brownells.com/aspx/learn/learndetail.aspx?lid=12616
Last time I checked oil was a rust inhibitor and the main ingredient is oil, heck Convair, an aerospace contractor, first used WD-40 Multi-Use Product to protect the outer skin of the Atlas Missile from rust and corrosion.
That's funny, then why don't they still use it? You know why? Because it's also flammable as shit. How do you think it evaporates so fast? There's lots of naptha in it. Just remember to breathe those toxic fumes nice and deep when you're using it as oil to get that great upper respiratory infection.
