You love your Mr. Coffee Ice Tea Maker, but now that you've used it a bit, you notice it's getting a whitish buildup in the machine and pitcher. According to the Mr. Coffee company (see link in Resources), you should clean your tea maker after 40 brew cycles if you have hard water, and after 80 cycles if your water is soft. The answer is probably already in your cupboard--white vinegar.
Pour 1 quart white vinegar into the water reservoir. Dump one tray of ice into the pitcher. Place the steeping basket in the pitcher and set the pitcher on the machine as for a normal brewing.
Turn on your tea maker and allow approximately 1 cup of vinegar to run into the pitcher. Turn off the machine and unplug it from the outlet. Allow to sit for 30 minutes.
Plug your Mr. Coffee unit back into the wall outlet and turn it on, allowing the rest of the vinegar to cycle through.
Remove the pitcher and, with the steeping basket still in place, set it aside for 20 minutes. This allows the vinegar to dissolve any lime deposits in the pitcher and steeping basket.
Discard the vinegar. Rinse the pitcher and basket with cold water.
Fill the pitcher to the fill line with cold water and pour the water into the reservoir. Dump one tray of ice into the pitcher, replace the steeping basket and run through an entire cycle as if you were making tea. Repeat this step once to completely rinse out your machine.
