Is the H4i standard tub (PN 26952) cleanable?
Yes. On a daily basis, you may use warm water and a mild detergent to clean. Use the new cleaning plug to properly secure the water/detergent for cleaning. White powder or deposits in the chamber can be cleaned by using one part vinegar to 10 parts water, utilizing the cleaning plug as a measuring device (see User Manual for details). However, the heating plate at the bottom of the tub cannot be taken apart from the base for cleaning.
