I am looking for your recommendation re: cleaning my fuel tanks.
Last year I used vinegar and baking soda to accomplish the bulk of the cleaning. Some surface rust remained.
Prior to installing them I wanted to see if I could remove the remaining surface rust.
So... last week I used diluted muratic acid followed by an acetone wash. The result was great ... bright shiny bare metal!
When I checked them out this weekend the bare metal was now covered with “flash rust”.
Looking for suggestions to remove/prevent the “flash rust”.
Thanks in advance.
