@mikemalter - I suggest calling The Disc Doctor (web search is your friend) to get his recommendations. He's an actual chemist that has been working in this space for a long time and is the recognized expert in this field. I have been using his products for a years. He has an expert knowledge of what needs to be cleaned from the grooves and what will effectively act on that material.
I won't recommend any kind of homemade record cleaning fluid when there's such a good source of information and and cleaners available through The Disc Doctor.
