We are (hopefully) moving soon to a building w/ coin-op. This will be our first attempt to CD w/out free W&D and we are worried that it may end up costing us too much. So, my questions are: 1) How frequently do you wash? and 2) What is your wash routine? I have been doing cold rinse, hot wash. I sometimes do an additional rinse. But I'm wondering if I could just go straight to the hot wash and skip all of that rinsing. Anyway, any advice is appreciated.
