Keurig machines have taken care a LOT of that

Any Keurig type machine with a water reservoir grows mold very quickly in the reservoir and in any of the tubing, nooks or crannies that always holds water. Anyone with a Brita pitcher knows this if they've left the pitcher out of the refrigerator for a few days.

Really ?

I have a Keurig machine for over three years and NEVER had that problem...we go six months between cleanings with white vinegar...

Isn't most public water system sanitized and cleaned before it flows into your home?
