Clean the inside of your machine by running water through it. Each machine will have a slightly different process, and some manufacturers provide tips and suggestions in user manuals. CoffeeLounge and other suggest mixing 2 oz. of vinegar in 20 oz. of water every now and then to clean out the machine even more thoroughly. After you use vinegar, though, be sure to rinse it three times with water to avoid any lingering vinegar taste in your next espresso.
