Aquatic turtles spend the majority of their lives in the water and if their tanks are kept clean, rarely need a special bath. However, your turtle might benefit from a cleaning if it starts to develop algae on its shell, or when it is shedding to help remove dead skin cells.  When your turtle is shedding skin, you may notice flaky patches of skin on its neck, tail or legs. This is normal.

Do not use any kind of soap or polish on your turtle, this could injure it or make it ill! This is the perfect time to check your turtle all over for any sign of injury or disease.
