Anyone know for sure which is the best product for sanitizing and cleansing? I have been using sodium metabisulfite but wanted to eliminate the need for rinsing. I recently bought a tub of one step, after that is was lead to believe it does not have very long storage time. ie. mix a batch do the work throw it away. and that it isn't a very good sanitizer. can anyone give me some advice on what to try or if one step is an acceptable product.
