ABSTRACT:
A cleaning mechanism for phonograph disc records includes a probe, and preferably a pluarality of probes arranged in line abreast relative to the direction of record rotation, for engagement within the record groove to remove particulate matter entrained therein. Previously cleaners have been brushes with fibres which inefficiently trail along the record surface. The probes maintain a bulldozing cleaning action and are preferably wire having a tip part inclined at about 90.degree. to a mounting part which is held in a carrier over the record. The carrier has means for dry cleaning such as a pad to pick up particles, or for wet cleaning including a liquid reservoir and dispensing means supported therefrom suitably from a pivoted arm. The carrier may be supported from a radially extending beam or a pivoted arm disposed in a leading attitude, in a manner permitting tracking by the probes of the record groove.
