A non Cholov Yisroel K-kup was used in our school Kuerig machine. Can it be Kashered?
Thoroughly clean the needles and K-cup pack holder as per the Keurig instructional video here.
Pour in detergent.
Replace the cup holder with a new K-cup holder (a replaceable part).
Do not use the machine for 24 hours, and then run two boiling hot water cycles (without a K-cup) in the machine.
Do not rely on this for Pesach Kashering.
