Do any of you do this? Aside from RODI rinse? I am leery of using soap, but I am noticing some hard water residue and films on some of my glassware from my test kits and presume that can throw the tests off. Rinse with H2o2? Run through the dishwasher with no soap? Worrying too much about soap?
Thanks for any input.
