[QUOTE=TommyT;368778]Help.... for the life of me I cannot remember what I'm suppose to pour into the Air Conditioner drain once a year to keep it flushed out. I've done a search and saw many, many posts about Bleach and other things, but I'm looking for a tried and true measure.
What do you use and at what mixture ????
TIA
