2 Tbsp of Borax dissolved in a full coffee pot of water. Run the same borax water through 2 full cycles of your coffee maker. Rinse pot and run another cycle of plain water. Rinse pot and basket. No more stains or coffee grounds residue in basket. Do this once a month.
No elbow grease required! I know there are other coffeepot cleaning methods. If you have more please share!
