Well, if you think Fremer's extreme...Yes, I would recommend using the Orbitrac before the 16.5. The theory is the felt strips on the 16.5 get dirty if you don't and then dirty up the rest of the records, which made sense to me, as did trying to preserve my Grado cartridge for as long as possible. Hence, I use the Discwasher first, then clean with Torumat, applied with new baby spit cloths(cotton, and cut into squares). No spare turntable, so I use the Orbitrac rubber mats and apply manually. Then rinse with triple distilled water. Dry with another piece of cotton if needed. Apply Disc Doctor fluid same way and dry with Orbitrac. Then on the 16.5 with VPI cleaning fluid. Gruv-n-Glide follows. I buy most all my records used from the used record stores locally. New ones get a Disc Doctor- Orbitrac- 16.5 with VPI cleaning. I get a good quiet background and good sounds. I admit to wondering if I could get the same results with less effort, and to having a backlog of stuff to clean, but I'm happy with the results and now that I've confessed my obsessive ways, I even think I feel better.
