With a semi-manual machine (or should it be called semi-auto?) like the VPI 16.5, you apply fluids, and scrub manually.
Therefore, Fluids can be applied, let sit, so they have the proper amount of time to do thier jobs, scrub to your heart's content, and when realy to remove fluids, the Arm Wand is swung over the Record, and vacuumed up. (There's two switches on the 16.5, one for Platter Rotation, the other for Vacuum Operation)
By missing this crucial step of more efficient removal of fluids, it doesn't matter if you're using the best cleaning fluids, and brushes in the world, you are not getting all the contaminants off the record by simply wiping dry. You are leaving much of them still in the groove.
As for RRL CLeaners, which is now Mobile Fidelity, thier older formulas such as Super Vinyl Wash, and Super Deep Cleaner, which is what you have, countless have users with both positive, and negative results.
Biggest complaints of these products are generally not strong enough-not the proper concentrations of chemicals to remove heavy grunge-dirt-biological contaminants, and the other was the Vinyl Wash contained a Lubricant (glycemic?) that on one hand was stated to quiet groove noise a tad, but also slightly mask dynamics, and detail as well.
Mobile Fidelity I understand is now in the process of two new forulations, is in Beta testing I hear. and will no doubt be on the shelves soon?
An Enzyme based Cleaner is very highly recommended by many folks as a first step cleaner, and Folks Like Walker, AIVS, Buggtussle, and even Phoenix to name a few have thier very satisfied followers.
Usually, the VPI 16.5 RCM holds thier value quite highly from thier now new $540 Price Tag. Certainly not the best machine on the market, but definitely one of the more "affordable ones", and with proper techniques, quality Brushes-Pads, and the best fluids, should bring you to within 90%-95% of any of the mega-dollar machines like the Loricraft, Clearaudio.
The 16.5 is very simple in construction, is extremely easy to use, and even easy to repair should the need ever arise, which with care should last you decades of regular use. If you're into analog for the long haul, I highly recommend a decent RCM.
My biggest regret when I bought my new 16.5 last August, was that I didn't buy it 10-12 years earlier after I seen, and heard what it did for my records, both old, and new. Mark
