With proper attention to detail, fluids can be removed from disc recordings as effectively by either manual methods or with the assistance of a vacuum driven pickup. Limitations to the efficiency and effectiveness of the latter approach primarily involve the design of the vacuum orifice. The slot in the vacuum wand of most machines is sized and configured in such a manner that fluids tend to be evaporated as much as sucked through the tube and into an appropriate reservoir. This process results in sufficient turbulence at the face of the vacuum slot to aerosol fluids onto the vacuum strips and the record. At the least this necessitates that the wand be rinsed between wash and rinse steps, slowing the process down.
Modifications for VPI and similar machines:
1) Purchase a second wand and column, dedicating one to the wash cycle and another to the rinse.
2) Remove & rinse the single wand in distilled water between each wash-rinse step.
3) Use a small, notched aluminum loaf pan or similar container partially filled with distilled water & either raise it to the wand or lower the wand into the container sitting on the deck of the machine.
4) Manually remove the Cleaner & use the vacuum to remove fluids following the distilled water rinse.
** Cleaning fluids should be applied to the brush and then dispersed about the disc rather than directly to the record surface.** Rinse water can be applied directly to the record surface but the brush should be well wetted whenever it contacts the disc. We do not find the brushes supplied with current record cleaning machines to be adequate for either cleaning or rinsing. In our hands, the back & forth scrubbing motion described in our Cleaning Procedure affords a more consistent result than holding a brush down to a rotating record, even when bi-directional rotation is used and do not recommend this approach.
Allow the vacuum wand one revolution plus a finger width and stop. *The fine film of moisture which remains after the Cleaner is removed is advantageous to the rinse step*. The film of moisture remaining after the rinse cycle is thoroughly degreased & any lint (from cloth or paper) remaining after the disc is completely dry, is readily removed with a clean carbon fiber brush.
** Final drying of the record surface & label area should only be accomplished.by air drying at ambient temperature to prevent statically charging the cleaned surface.
Full area support is required for thorough scrubbing. Using a second platter mat on top of the primary work surface eliminates the need to clean the lower surface as you go from one side of the disc to the other. Some users prefer to clean one side of a set of discs, holding them in a vinyl covered dish rack or 2 until they're ready to repeat the process on the second sides.
