i use a Knosti wet cleaning system and had the best results than any other method including an expensive cleaning "machine", used with Vinylshelter cleaning fluid you will get brilliant results, for extra dirty records a "Tonar Wetgoat" brush can be used to pre-clean before going in the Knosti.I have a Knosti Disco Antistat but it is a fluid based cleaning system, also a carbon fibre bush if its simply dust.
Depends on your budget really.
Note: without wet cleaning it is impossible to clean even new discs thoroughly.....
