How do you replace the lips on the tube, Grainger?
I love my 16.5, too, but it took me a while to get the right routine for best cleaning. I, too, use the Audio Intelligent fluids, and highly recommend them.
My routine:
1. apply formula 14 to record using VPI brush, agitate a little make sure even distribution across record.
2. Let record sit for 4 minutes
3. Agitate fluid again for another 30 seconds or so
4. Vaccuum off (exactly 3 revolutions)
5. Apply pure water with a different brush (I use Audio Intelligent brushes). Agitate for a minute, making sure water gets into the grooves
6. Vaccuum off (exactly 3 revolutions)
7. Repeat steps 5 and 6
8. Put record in new MoFi (or equivalent) sleeve
The second rinse may be excessive, but I find it helps a great deal. The number of revolutions in vaccuuming is key. I was using 4-5 at first and this seemed to cause problems, I.e. static build-up, that negated some of the effects of the cleaning. I also dispensed with my MoFi brushes, which I felt were leaving a residue.
