Question

How do you properly maintain the filter holder on a coffee maker?

Answer 1

the easiest way is to soak it in a 50/50 mixture of vinegar and hot water if its a plastic holder you are talking about. If its a metal holder coat the holder with baking soda and dip it in full strenght vinegar.

Answer 2

You could always run a mixture of 50% water and 50% vinegar through the entire coffee making cycle. That way the mixture is the same temprature as the coffee when it flows through. Just do not put a filter in and let the water/vinegar mixture run into the coffee pot. This will clean any stains out of your coffee pot as well.
