tuning capacitor rust

[theblackknight]

A while ago, I remember seeing a Philco 20 cathedral for sale that was DOA. I remember looking inside and seeing the tuning capasitor covered in rust. Just thinking again, would a radio like that be fixable? I dont see how you could possibly fix a problem like that. Just wondering on your thoughts/opinions.

Im sure there is a commercial product available that will work but if you can't find one try ketchup,it does a great job on old pennies.By the way hi neighbor, i live in granite city.

I dont have one with that problem, but its not been discussed here and I just wanted to know for future refrence.

I would think something strong like CLR would work with a good soaking. However if there were any plastic parts they would melt.

Hello i have tryed many things like wd-40 3-in-one oil ect.I found Aero Kroil to work the best tho. It sprays on so i get q-tip wet with it and put on cap! Let it soak a day or to keep it wet.It should free up then clean with toothbrush and spray a good electronics parts cleaner on it. A bit of oil on ends should do it.Be careful not to put to much oil on it! Aero Kroil can be found at Kanolabs. Use google to find it Hope this helps! See you Afvel
