Initially, you can rinse your array with very warm water and pat dry with a towel. However, as the elements become pitted from use, putting into the dishwasher may help, or following this piece of advice below: Dip the array in a solution mixture 1 part vinegar to 2 parts warm water for a couple of minutes. Then brush the array to remove access particles and rinse thoroughly with warm water and pat dry. If you are using the foot bath in a professional setting, we would recommend the use of a good disinfectant cleaner rather than the steps noted above.
