DID NOT WORK!!
This was supposed to be the saving grace in my Dr. Dabber Switch, but apparently even THIS doesn't keep the percolator from clogging. The very first hit, it clogged. We clean the percolator, add twice as much Rez, and it clogged on the SECOND hit! Terrible waste of money. I'll try the cranberry juice, like that one dude suggested.
