Thanks for the reminder. My coffee pot is due for a cleaning. On another note, you don't want to know about the gunk in the ice maker line on the refrigerator. We took out the ice maker and didn't replace it. I can wash the ice cube trays. Check the seals on drink cup lids too. I take them off and scrub with a small brush.
Have you ever checked the inspection report at your favorite restaurant? Lemons in your water or tea? It's a wonder we survive it all. LOL.
