I am weird. I cut up a lemon and an orange and clean my coffee pot with them (the pot and filter). I also take everything apart and clean the small parts, too.
I don't know why, but it makes it shine!

This Cinnamon and Vanilla - "Snickerdoodle" - is a huge treat for me. If you live in California, it is sold in stores here. A lot of other places, you may have to get it online. The smell of the Cinnamon and Vanilla when it is brewing is to die for.
Mmmmm!
