      What is the current favorite for cleaning gas tanks? Is METAL RESCUE worth the cost, $25 per gallon?

        Steel or aluminum? I can tell you what I’ve done recently with 6 gal tanks:

        Pint of acetone sloshed around for a couple of days to dissolve polymerized gas/oil stuff.

        Hot water, TSP, and pint of stones shaken and sloshed around for a good while.

        Rinse.

        Tread with phosphoric acid solution such as Phospos or similar.

        Any actual holes patched with epoxy.

        Assuming inspection shows rust/scale gone and metal a clean grayish color.

        Coat inside with POR15.

        All this, of course, is a pain in the ass, not including refinishing the outside of the tank, making gaskets, and all that. Is there one cleaner that can do much of this in one treatment? If so, I would like to know about it.

          Assuming we are talking about varnish/old gas residue, etc. I use Castrol Super Clean. Mix it up heavy and use HOT water. Follow with another rinse of HOT water.
          Be careful, it does attack the paint, strong stuff.

            When deciding on the best procedure to use it is worthwhile to
            determine what has caused what you trying to remove. Rust
            and corrosion is a result of moisture so water base solvents
            usually produce the best result. Goop from dried up oil and gas
            responds best to solvent base cleaners. If your dealing with both
            removing the goop first and then going after the rust and
            corrosion seems to make the most sense but a water base cleaner
            that dissolve grease can be effective with time. If the tank is so
            rusted or corroded you end up with holes in it you should search
            out another. Even if you patch the holes in some way the tank is
            weak because metal is missing throughout the tank and it can
            puncture easily.

            A "Boathouse Repair" is one that done without having tools or the skills to do it properly.

              White vinegar can make miracles too in a steel tank.
              Same thing for electrolysis.
              And then , shaking the tank with a handful of screws / bolts.
              Before / after.
              Almost done, work in progress for now. Maybe I’ll pour it with a mix of mollasses and water later.
