Frequently Asked Questions
Corelle®
| Why are my CORELLE® cups or mugs staining? |
| Each community has a slightly different make-up to its water supply. Therefore CORELLE® cups may stain due to mineral deposits from use of untreated water overtime. The oils from coffee or tea will adhere to the sides of the cups because of the mineral deposits/residue in the water. These stains can be removed with a non-abrasive cleaner such as Bon-Ami®. Or, fill the cup 1/4 full with vinegar and dip and clean with a paper towel. Rinse and thoroughly dry. DO NOT attempt to use bleach to clean the stains as this will only lighten the stain. Please note that staining may reappear if the water used for cleaning is left untreated. |
