Going to change up my cleaning method. I have been using a heavy duty chlorine detergent followed by an acid rinse. Going to try a no rinse ammonium chloride detergent/sanitzer and do it all in one step. I'll pick up a gallon on Mark 10 today. Should be a very cost effective solution, mix ratio is 1-2 ounces to 4 gallons water, cost is $19 a gallon. Non foaming and requires 1 minute contact time. Stuff I was using before did a nice job, but required to be water rinsed before use. Can't help but think that would be a route to possible contamination. I will also admit that I like the idea of 1 step better than 3.
