| | Pickled motor? Meaning?
I use to do allot of QA work with piping and in cases where the piping had to be very clean and you did not want to flush it. We would pickle the piping this would be done using nitric acid to remove oil, flux ECT. What we would do was after the piping was welded together but not yet installed we would cap the ends and fill it with this solution for a set period of time to remove all oil, grease, flux and whatever else contaminated the piping. I'm sure that it is the same procedure just a different solution! Somthing I'm sure that will neutralize the salt!
