To provide a ball cleaner that can continuously clean and dry balls used in a children's play pool in a short time and that is simple and inexpensive.

The ball cleaner 1 has a cleaning chamber 2 in which a ball 4 is cleaned with a cleaning solution, and a drying chamber 3 in which the ball 4 cleaned in the cleaning chamber 2 is dried. The drying chamber 3 has a means to advance the ball 4 at a prescribed speed (moving annular belt 12), a porous absorbent 21 laid over the floor of the drying chamber 3 to absorb the cleaning solution sticking to the surface of the ball 4, and a chute 22 that can be set in a decompressed state and intended to drop downward the cleaning solution impregnated into the absorbent 21 for collection.
