Ball washer

Because golf balls have a dimpled[1] surface to improve their aerodynamic properties, increasing both distance and control, and are used primarily on grassy surfaces, they tend to collect dirt and grass easily, which can adversely affect their aerodynamic characteristics.

To maintain these aerodynamic properties balls are usually inspected for dirt before play, and washed if required.

Ball washers can be operated either manually[2] or electronically.

The cleaning of the ball takes place via circulating brushes.

[3] For cleaning a larger number of golf balls, machines[4] are used which suck up the balls like a vacuum cleaner, wash them, and put them in a separate net or dispensing machine afterward.
