I once called Munn's and asked them why their technicians only recommend using hot water, because their website had an old FAQ that recommended using vinegar. They told that they needed to change their website because Carrier had told them to only use water. No vinegar. I use a gallon of hot tap water about every month.

I also have a "Drain King" that I bought from Amazon that is a small rubber tube that you insert into the drain pipe and connect the other end to a garden hose. When you turn on the water, the tube expands and seals the pipe and allows a thorough flushing of the condensate line, with no backflow. Very handy device.
