   • Clean the tank and base with a soft cloth and a mixture of white vinegar and water (1:1 ratio). Do not submerge the base in water.
   • Gently wipe the ultrasonic mist transducer (metal disc inside base) with a vinegar-dampened cloth to remove mineral deposits.
   • Rinse all parts thoroughly with clean water and air dry completely before reassembly.

WARNING! Never use abrasive cleaners, detergents, or chemicals. Never immerse the base unit in water.
