Just installed a 55" LCD at a neighbors that has DTV and they asked about my bag. We talked and I brought up wanting to try "mold release spray", but what I have found is expensive. Well the wife makes soap and has many different kinds of inexpensive mold release sprays, several which claim industrial properties, of which I am dying to try. Unfortunately, we're in a drought here in Denver and have had no snow that would allow us to test. Had to water the lawn the other day and waited for later in the day so when I blew out the system I could make my own snow. It worked great.
Anyway, I have sprayed one brand on my dish and another on theirs. We'll have to see what happens. Sure would like to not to have my yearly "Bagging of the dish" ceremony. There's many other reasons for cocktails.
