Do try the Disk doctor, I use that. I have used a few out there and disk doctor seems to work the best.
What to use if I just want one cleaning fluid?
I'm willing to consider distilled water as a post cleaning rinse fluid (g). But if I'm going to use a VPI cleaner for my disks, and I want to use just one over-the-counter fluid to clean both new and old records in an acceptably effective manner, what should I use?
