How do I clean the ultrasonic plate of my humidifier?

If your humidifier is scaled, we simply recommend using white vinegar and water. Dilute the vinegar in 50% to 60% water, leave for 10 to 20 minutes and rinse. Be careful not to rinse with too much water, as this could introduce water into the electronic part (which would damage your device). You can also use specialized products, such as Cleaner&Descaler from Stadler Form.
