I've been lurking long enough to know that there are some vinyl enthusiasts on here, so I'm going to put this out there for feedback: what do you use to deep clean vinyl and why?
I already have several 'light' cleaning solutions (carbon fiber and discwasher brushes) and a stylus cleaner, so I'm all set for getting surface nasties off. I know that deep cleaning can become an expensive task with the vacuum machines, so I'm particularly interested if anyone has compared one of those solutions to other, less expensive 'elbow grease' methods.
My motivation is to record some of my rare (no digital equivalents available) vinyl to digital and I want it to be as clean as possible. In all cases, these discs are scratch free, but old enough to have a lot of deep dirt.
