I worked on a drill ship in Mobile bay, back in the late 70's. We were doing a refurbishing job, running air tools & knocking rust off, sandblasting & usin Ospho, a dilute Phosphoric acid that turns iron oxide, chemically, into iron phosphate, so, the rust is GONE, it wont work thru scale, one layer deep, only, about 12 bux at Kelly Moore, dont get the gel,, liquid only. I use abut 1 qt a year. maybe less,, but I keep it around.
