I use VPI16.5 as well, I use MoFi cleaning solution and a bit of scrubbing with Disc Doctor brush, then vacuum for one round. Then about 5-10cc of 18 MOhm Deionized water (having my own chem lab has its benefits), spread with VPI brush and vacuum for 1.5-2.0 rounds. Dry for a few min, then put a clean mat on VPI and wash the other sides.
The wand can be rotated from 90 to 80+ degrees (check VPI manual) so that only the leading edge touches LP surface. This way LP will be dry after vacuuming.
