How do you clean your giant Asian pond turtle?

Hold your turtle under gently running warm, like 80 degree F., water or let him soak in a bath of 80 degree F. water. While he is in the water rub his shell and plastron with a soft wash cloth to remove dirt. If he has algae stuck on his shell then gently scrub it off with a children's or soft toothbrush. Don't use any soap, shampoo, conditioner, or cleaner, just water. Don't scrub the shell of a soft shell turtle or young turtle who's shell hasn't hardened yet.
