I have a 31 year old 60 gallon vertical asme air compessor tank that has rust on the inside, especially the bottom 1/6.
Would there be any downside to electrolytically removing this rust?
I would fill the tank about 1/4 with a water/washing soda solution, then fabricate an anode that would fit inside through the inspection port, insulate the anode from the tank, then use the body of the tank as the cathode.
I'm worried about causing harm to the steel tank. I have electrolytically cleaned a lot of small items and noticed that rust does come back in short order unless you somehow protect the steel after the process. I would imagine that this would be a problem in a humid environment such as the inside of a compressor tank. Any thoughts on how to protect the newly derusted interior, assuming of course this is a sound application of the electrolytic process?
