Your supposed to clean them?
just when the red Descale light comes on I found out. And if you descale with the homemade vinegar recipe you will taste vinegar in your coffee for a while
Every time I've tried descaling one it's clogged it up and won't work any longer. We still have one though for convenience sake. It by no means makes the best coffee. When I have time I still bust out our old percolator to make a pot of coffee, my favorite way to make it.
