The problem I have found with the Disc Doctor cleaning fluid is that it takes a few plays before it sounds good. I have rinsed and rinsed and still have found the record to sound a little dull on the first play. I don't use it anymore because of this. Maybe what Rushton says about it taking a few days for it to clear up works but I usually want to play my record shortly after cleaning. It seems like the DD fluid might be best for really dirty records that need scrubbing to remove the gunk? I prefer the sound and quick use of the Record Research Labs products. I think they go by another name now (Mobile Fidelity) but it is the same stuff. It is a two part process if you have dirty records, but most of the time I just use the quick rinse cleaner and the records usually sound great.
