I tried and I tried and I tried, but to no avail. I used all the suggestions from other reviews and still got a weak grainy coffee. Took my Keurig back to the store and I'm back with a real coffee maker. I wanted to try the my Kcups because the store bought are not environmentally sound. I went to the Keurig site and they even said you cannot recycle the plastic but they're looking into it.
