Open the top of the biem, fill with warm water and a drop of dish soap, then close securely. Press the on/off button once and wait for the blue light to begin pulsing. Then, press and hold the on/off button for five seconds to initiate the cleaning cycle, which is indicated by the power light turning solid blue. Spray for at least 10 seconds, then open the top of the biem to empty the extra soapy water. Repeat the cycle using fresh water and no soap. Spray any remaining water out if desired before inserting a stick of butter, and you are ready to biem away!
