A damp cloth with a mild, lukewarm soap solution is sufficient for this. Clean the green outer skin of the Backpod.
Please do not clean the Backpod under running water or even immerse it in water. This could fill the blue core with water that you cannot remove afterwards.
Under no circumstances should you put the Backpod in the dishwasher or microwave.
The Backpod should not be taken apart. Turning the green outer shell upside down can result in cracks.
