Re: How best to inexpensively clean degraded variable caps?

As far as expensive, yes DeOxit isn't cheap, but then it doesn't look like you need to buy a new capacitor at $20-$60 either and can refresh existing ones multiple times, instead of replacing. Alcohol is cheap and seems to work good too. Both can be used without cap removal in many cases. Dawn soap, water and a fine long-bristled brush would work too, but you would need to remove, clean, dry and possibly relube the bearings and gearing before reinstalling the cap. I like the spray clean and canned air dry method the best!
