    Geeze man, did you even try to look for the information? There are dozens of threads on this topic, including one posted just a few days ago.

    There are various acceptable methods to clean a tank. First remove the petcock, fuel sending unit as applicable, and the fuel cap, and fashion some water tight plugs. Then dump in one of the following: Kleenstrip Metal Prep (phosphoric acid) as available at Home Depot (my recommendation), vinegar, or Evaporust. Install the plugs and shake the tank as often as you can to keep all surfaces wet. If you use the Metal Prep you can dump in one gallon and then add water to completely fill the tank to the top. Wait long enough to fully derust the tank and then rinse with water. Quickly dump in some alcohol and WD-40 after rinsing to ward off flash rust.

    All this is covered in the other dozens of threads on this subject so you may want to review further for more information.

        ummmm... because you can't digest what you read previously?

        Geeze, man...

        The information is out there... repeatedly!

        By the way, welcome to the GSR!

          Just a caution about leaving an acid in the tank too long. It can eat through the metal and create pin hole leaks.

            Geeze, man, cut him dome slack! He's new here!
            Not like he's making a bobber out of a pristine 1000S.
            OP, have you read about electrolysis for cleaning tanks?
            Science instead of nasty chemicals, no flash rusting afterwards.

              Yeah Tom... he said he has been reading about all the different methods, and then asks if any of us know a good method... LOL

              I have only de-rusted two tanks. I used Evaporust from Home Depot (or perhaps Lowe's) both tomes. It worked well.

              It isn't rocket science...

                      So what is your question that the other threads you read didn't answer?

                        Ask a a better question to get a good answer.


                        Perhaps his questions was worded badly....

                        He should've asked - "What is the preferred or best method to de-rust the tank of all the ones I have read about ?"

                        Then the curmudgeons might've cut him some slack


                        I know some here have immense experience - but to a newbie some of this can be overwhelming - even when reading the tutorial.

                        I had to re-do my valve adjustment 3 times before I got it right - and I had the tutorial in my hand...

                        I must be slow learner -- or NEW to the activity.

                          I like this answer. Wording is everything. The intent may not be written to prevent curmudgeon replies. Geeze!

                          EDIT: Who came up with this word? It fits the description to a tee! curmudgeon: a person (especially an old man) who is easily annoyed or angered and who often complains

                          EDIT #2. The above word was used in Season 6, Episode 8 of Downton Abbey; same night I referenced this definition.
