Gresham. That little tidbit phosphoric acid came from the field and not in school lol. Between undergrad and graduate school, I took a brief job at a medical solutions company (making all those various IV injection solutions). The giant SS vats were often cleaned with phosphoric acid to halt any rusting/prevent
Mike, perhaps Roc was refering to me saying Phosphoric acid since we try and avoid phosphates in the tank.
And in reply to Roc, proper flushing with clean water should handle it. Plus, we test for phosphates so you could easily test the final rinse water.
