I removed my tank from the boat and successfully siphoned, then rinsed, out 30+ yrs of sediment, using a strong detergent and lots of water. I then dryed it thoroughly by forcing air through it for two days.
But on close inspection through the access holes I see a layer of varnish scale on the sides from about a quarter tank level on up. Obviously it sat a while at one point. Anyway I have all winter to get this perfect and I'm wondering what home remedy there is to eat that varnish off. I don't want to use a volatile solvent because I don't want to re-arm the bomb, so to speak. I'm thinking Muriatic acid, or something similar, but of course I don't want to compromise the aluminum.
If anyone has a suggestion I would appreciate the input.
Thanks in advance,
Joel H.
