How does one clean a turtle tank?

Answerin a sink get the water flowing to be a similar temperature to the habitat, luke warm. Make sure the water is gentel, not full blast but you want more than just a trickle. Hold the turtle under it by it shell. Expose the head and each limb to the running water. or you can fill up the tub or sink and just letting it swim in fresh clean water gives it a bath! make sure youlightly scrub the shell! what i do to my turtles is that i have a special toothbrush just for them,and lighty scrub the shell with special shampoo made for turtles!! yu can but it at petco
