The part of my coffee maker where the water goes gets gross because of the type of water we have, but I have tried running vinegar through a few cycles to clean it, and that didn't work very well. As far as the actual pot, I will run that through the dishwasher once in a while, but usually I just add salt and ice and mix it around. That works well, but any other tips on cleaning the coffee maker? How often do you/should you do it?
