A cleaning apparatus for computer pointer devices (9) having a standard ball (15) contacting input rollers (13a, 13b) has an abradant ball (21) mounted to a rotary shaft (25) in a manner that the abradant ball (21) may be brought into contact with rollers (13a, 13b) of the pointer device (9) with the standard ball (15) removed, the position of the abradant ball (21) such that rotating the shaft (25) will rotate the abradant ball (21) in a manner that the abradant ball (21) with both abrade and turn the rollers (13a, 13b). The cleaning apparatus may be a hand-held device, built into a free-standing housing, or into a housing as part of another computer housing, such as a computer or display. In some cases there is a variable speed drive with user settable speed, and in some cases there is a vacuuming system for removing abraded matter from a pointer device while cleaning takes place.
