    Good video. Just a couple of comments from a chemical engineer. Usually the tarnish and buildup from old gasoline is a result of olefin polymerization (olefins are high octane hydrocarbons from fluid cat cracking units in the refinery), the trace amounts of heavy ends in the gas, and the residue from the detergent/additive package mixed into the gas. Acetone is an OK solvent for this, but I reckon you will get better results from an aromatic such as toluene or xylene. Toluene can be bought from a big box DIY store (my local home depot carries it for about $20/gallon) or sometimes cheaper from a paint store. Incidentally the acetone will do an excellent job of drying out the tank after a water wash. Shake as much water out of the tank as possible and then rince with a pint or so of acetone; it will greatly aid in evaporating the water.
    I noticed another commentator suggested muratic (i.e. hydrochloric) acid. I would not do that, especially on a rare or unreplaceable gas tank. Hydrochloric acid is incredibly corrosive to mild steel. It sometimes has a corrosion inhibitor included but if you get any into a crevice or fold and don't get it all rinsed out it will be game over for that tank. If you are disinclined to use toluene (or acetone, for that matter), I would suggest a strong base rather than an acid, namely sodium hydroxide, also known as caustic soda or lye. It will dissolve the tarnish and form an emulsion with a little water, which can be easily rinsed out. Caustic is not corrosive to steel at ambient temperatures. It is very corrosive to flesh, though, so all of the safety precautions recommended by OSHA must be considered to be mandatory. The same would be true of muratic acid. A drop in the eye of either would likely mean blindness.

      Thanks for this input, much appreciated! I actually have never thought about xylene but have used it for different purposes. A lot of good information and suggestions and I'm sure many will find it useful. Thanks again!

    I used a 3500 psi pressure washer on my tank. I was able to put a 90 degree fitting on pressure washer wand and get all the surface inside the tank. It removed all the varnish and built up.

    I did something similar to my '87 W-150 after replacing the 3rd fuel filter in 3 months I took down the tank, bought 3 bags of marbles at Wally world with a gallon of diesel fuel and shook the you know what out of it, cleared her rite out. Thnx 👍👍🇺🇸🇺🇸

    Couple years ago I used electrolysis to get rust out of the tank for the 68 D200. It worked but took a long long time. Finished it off with a quick hydrochloric acid rinse, then flushed it several times with water.
    Now someone makes a repo tank for those. 😆

      Use vinegar & soak overnight repeat if necessary with fresh vinegar. And wash it out with baking soda and water. That should do the trick but you also want to seal your tank after with tank sealer because it will rust again and flash rust don’t skip the sealer it will last you another 10+ years

      The only trouble with a radiator shop is that they're getting harder to find. When I first started messing with cars, every town with a post office and two bars had a radiator shop. Today, I'm not even sure if there's one with in an hour drive of where I live.

      That's true. The last rad shop closed up here many years ago. I was also thinking electrolosis will work@@bobbyz1964

    I’ve found if you put 3-4 gallons of e100 (the PURE alcohol fuel) in the tank, plug all the holes. Then motorcycle strap it in the back of a pickup. Drive it a week Turning it a few times in the process. It’ll come out squeaky clean.

    All I have is varnish from old gas in my motorcycle tank, won't the Acetone harm the coating inside?

    Green stuff? The tanks I have worked on have red varnish in them. It seems to resist lacquer thinner, acetone & alcohol. Back when there were radiator shops I had one hot tanked & that worked quite well but left a lot of brown powdery residue that took a while to completely remove with a garden hose. Never had one with green residue. You are taking a risk using a steel metal brush because it could cause a spark. I would use a nylon or brass bristle brush.

      I was thinking the same thing, holy crap. Have you ever seen a gas tank with the perfect air fuel mixture pop? Acetone has an even wider LEL to UEL limit than gasoline making it easier to pop. Even the amount of fuel it would take to just wet the inside of the container would be enough to pop and burn off half your skin. I would suggest you take that part of the video out.

    If you use muriatic acid you do not have to scrub the tank.
