Cleaning question

[Frump]

Turbo parts are nearly impossible to find, hopefully that won't be an issue. The turbo shouldn't and doesn't appear to be nearly as dirty so far.

We still have to do the sheet metal screw treatment. I have water based evapo-rust remover which we are going to try, but we are going to water it down and let it sit for several days. The rust remover stuff is pretty expensive, something like $100 for 5 gallons. We had soaked it cider viniger for a week or so earlier, just not the cap area. Cleaned tank out at the car wash Saturday with warm soapy water, that helped get a lot of the remaining residue out.

A portion of what we got out in November through the petcock holes and the fuel sensor hole (quarter to show size):


What inside looked like after warm soapy water wash:


I have a second tank, it has less rust, but needs dent removal and more paint. Would like to use the rusty one if we can. I'll take some more photos to show what we end up with.
