I've had an aero press for years and love it. However, I find that the inner cylinder sticks a bit. It is sometimes very difficult to eject the little coffee puck of grounds to clean it after use. Any suggestions to make it work a little more smoothly? – From Barbara D.

I am very glad to hear that you enjoy your AeroPress. I have three suggestions that I think will help with your problem. First, soak your chamber in vinegar for ten minutes or so and then wash it thoroughly with soap and warm water. Second, remove the seal from the end of your plunger and thoroughly wash the seal in soap and warm water. Then put the seal back on the plunger and try your AeroPress. If it is still difficult to eject the puck, put a little vegetable oil on the edge of the seal to provide a lubricant.
