Re: 6 gal pressurized tank-3 prong
I thought is was a hoot for rust removal.

Pay attention to:
"The commercial chelation de-rusters target only steel oxides, so they will not bother copper and brass. Molasses may attack other metals, so take care how you use it."
Using steel shot, nuts/bolt/nails/screws, or other items to mechanically remove the larger surface scale will probably speed up the molasses chelation process.
I just can't help myself: You should have a sweeeeet gas tank after that.
