Total Iron — A. First, clean the CELL with 0.1N HCl, Distilled Vinegar (5%), or Muriatic Acid (diluted
1:40 with H2O) before testing. B. If running multiple tests in a row, using the same water sample, the
CELL does not have to be rinsed or cleaned with acid between each test. It is recommended that the
CELL be rinsed 3 times with the sample water.
