I ordered a 55 gallon drum of that stuff to try with my pressure washer:
rust remover
I ordered a couple of 5 gallon tubs last year and have used it "as per the instructions"... soaking for extended periods of time (30 minutes to 2 days). How can you use this with a pressure washer? My understanding is that there must be either immersion or constant contact with the metal in order for it to work its magic.
