Call Disc Doctor (see his web site) and ask someone who has been studying this for years. He'll probably suggest some kind of vacuum record cleaning machine and he'll fix you up with the proper kind of cleaner to address your needs.
And yes, he is in business to make money. But he wouldn't have lasted all these years if he was producing an inferior product or giving bad advice.
