If your Echo Go+ bottle needs to be cleaned, normal dish detergent can be used to clean by hand. Do not put your Echo Go+ in the dishwasher, and do not submerge in water. When hand washing avoid getting the generator electrical components and charging port wet.
Depending on the mineral content in your filtered water, you may need to clean the electrodes once or twice a month. To descale, add 1 part white vinegar, lemon juice, or citric acid and 3 parts water in the bottle and leave generator soaking in mix overnight.
