Sanjay,
As you're well aware, the VPI really does nothing as far as cleaning goes, other than offering a platform to place your record, and then a vacuum to revove fluids, and the suspended nasties. But you have jumped over the highest hurdle, buying the RCM, the rest is relatively easy.
The VPI Brush isn't a bad brush, and being Nylon, it will stand up to cleaners containing enzymes, an alcohols.
Brush Pads from Lloyd Walker, AIVS will be of better quality, and will perform better. Brush Pads from Disc Doctor-Mobile Fidelity work very well too, I'm happy with these, but some do note a larger quantity of fluids being used to initially prime them-wet them. Nice thing about these, the pads are replaceable.
Use one dedicated Brush for each step, and label them, to assure you don't mix cleaners with a certain brush.
Yes, if you've read between the lines, you've gathered I am suggesting a multi-step cleaning process, rather than a one step cleaner. A cleaning process such as AIVS 3-step, you first remove any really nasty dust with a CF Brush, place on Platter, begin with the first Enzyme Cleaner, with Platter Spinning apply evenly with brush that the entire surface is covered, but avoid the label area. Now stop the Platter, and let this product sit for 3-5 minutes on average, (don't ever let any product dry on an LP!). If due to dry weather conditions, and you notice evaporation, apply a little more, and this is easy to do with Platter spinning.
After a period of a few minutes, only then you begin scrubbing, cleaning the LP in a back, and forth motion 8-10 times per section, following the grooves, do 1/3rd of the LP, rotate Platter, to do the next 1/3rd, and so on, until the entire LP has been scrubbed. Only then activate vacuum to remove cleaners.
Remove product, and go onto the next step, with its own dedicated brush, and repeat.
Lastly, will be the Pure Water Rinse. Again, use a dedicated Brush, and some even go as far to insure the least amount of cross contamination, they use a entirely different dedicated Arm Wand, (About $60 from VPI) swapping it out, which takes two seconds, for the Pure Water rinse.
Minumum is one good rinse with ultra pure water, and another rinse per side will not hurt anything, and will insure all cleaning products are gone. Do inspect the LP surface after vacuuming. Two revolutions should get the LP virtually dry, more than this can build static, and less will not remove all the rinse with the 16.5 RCM.
Try keeping your Platter clean, when doing the flip side, insure that when done, no fluids have dribbled over onto the cleaned side. I usually use an unscented Kleenex, and hold to to outer bottom edge of LP while platter is rotating with the vacuuming process to insure no dribbles of fluids are left.
Inspect both sides, insure they are totally dry before inserting into Inner Sleeve. Practice makes perfect, but your machine will only work as well as the fluids, and brushes you use, and patient, sensible techniques.
Hope this helps, Mark
