Cleaning the Decanter
Hard water can leave a whitish stain on the decanter, and coffee may
then turn this stain brown.
To remove decanter stains:
1. Fill the decanter with a solution of equal parts water and vinegar and let
the solution stand in the decanter for approximately
20 minutes.
2. Discard the solution then wash and rinse the decanter.
Do not use harsh abrasive cleaners that may scratch the decanter; scratches
may cause the decanter to break.
