To clean, wipe the outside and inside of the unit with a soft cloth and mild detergent. Do not use abrasive cleaners as surfaces may be scratched. Take extra caution when cleaning the LCD display and the window. The shelf tray is removable and can be hand-washed with warm, soapy water. Rinse and dry completely before returning it to the unit.

With the app you can turn the unit on and off, adjust the temperature, switch between °F and °C, control the interior light, and turn ECO mode on and off. Note that the app displays only the set temperature, not real-time temperature changes.

The Sourdough Home Plus is designed to maintain a stable environment for your starter, not to hold a precise air temperature.

For the most accurate reading, use a probe thermometer inserted directly into your starter after it has been in the unit for several hours.
