Clean with dish soap and water, then soak in 100% white vinegar for 10 minutes or soak in 50/50 mixture of water and vinegar for 30 minutes. If more than one person is using the array, soak in a hospital grade disinfectant for 10 to 30 minutes, rinse with water and let air dry. How Many Sessions Are They Good For? Each detox array can deliver between 50-60 sessions if properly cleaned and maintained. The stainless steel material allows our detox arrays to last twice as long as our competitors. Special Note: The BioEnergiser foot bath is not compatible with our detox arrays. There is a special adapter you can use to convert plug types but we do not suggest it.
