How do I clean Joule?

• Thanks to Joule’s seamless design, in most cases you can simply clean it with a damp cloth or sponge and then wipe dry.
• To keep Joule running smoothly over the long haul, we suggest cleaning it periodically in a vinegar bath:
  1. Pour equal parts water and distilled white vinegar into a small pot.
  2. Add Joule, use manual mode to set the temperature to 140 °F / 60 °C, and allow Joule to heat the liquid. 
  3. When Joule alerts you that it has reached that temperature, the cleaning is complete. If you have hard water, cleaning with vinegar is an important way to remove buildup inside Joule, which can result in a whistling sound and/or slow heating times. If Joule starts whistling or heating times seem longer than usual, this may be a sign that your sous vide tool is in need of a bath.
  4. Although 140 °F / 60 °C is preferred, running a vinegar circulation bath at a lower temperature can still do wonders for cleaning / de-scaling. (Even at Joule's minimum temp of 68 °F / 20 °C.)
• If it's been a while since you cleaned Joule, making a bit more noise than expected during circulation, taking much longer than expected to heat up the water bath, or receiving a low water message, try running the vinegar circulation bath for 20-30 minutes.
• To clean the inside of Joule, take off the metal foot of the device by twisting it counterclockwise, remove the propeller, and then use a wet sponge or bottle brush to gently wipe out the inside. If food has become cooked onto the heater, use a nylon or brass brush to gently clean the interior, being careful around the soft rubber seals at the top of the heating cavity.

WARNING: Do not put Joule in the dishwasher, and do not submerge Joule in water.
