Golf ball washing device with internal overflow

A golf ball washing device is provided which includes an internal overflow. The golf ball washing device includes a shell having an cavity which holds cleaning liquid, an agitator movably connected within the cavity, a stand having a hollow portion attached to the shell, and an overflow passage. In preferred embodiment, the overflow passage is a tube having a first end which is connected to the cavity and a second end which communicates with the hollow portion of the stand. The shell is cast to encase the overflow passage. During use, when the agitator mechanism causes the cleaning liquid to splash or otherwise rise above its normal level within the cavity, the overflow passage drains the excess cleaning liquid from the cavity into the stand. With this configuration, the overflow passage prevents cleaning liquid from spilling or splashing outside of the shell.
