Quilty-Louise,
I have a Keurig and one thing I found out was that if you use the k-cups, the holder to the k-cup (the black part) make me lodged. If you check the manual there is a small trick to use a toothpick into the "puncture" part and then clean it. My keurig did the same as yours and I never had a problem since. And yes the utility fabrics are on sale at Joanns> May go today for that purple paisley one hope I can find it!
