Damaging records with a hand turned machine.

Xiekitchen, I am not sure I agree with you. I beleive the cleaning fluids do most of the cleaning, aided by the brush. I don't think alot of pressure is neccesary. Just enough for the brush to reach as close as possible to the bottom of the grooves. I would think too much pressure could make small (probably inaudible)marks on the vinyl surface. It probably depends on the type of brush used.

Yes you can.
If the dry side of the record is facing a dry pad and you are simultaneously dragging the vinyl with a downward pressure across a dry pad, then any dirt on the surfaceof the vinyl will be scraping across the vinyl. Just be careful to never drag vinyl dry over any dry surface: no matter how soft except the dry micro carbon brushes like the Hunt E.D.A or Audioquest. After using the manual Nitty Gritty record vacuum a while, I realized it is best to keep the record stationary and rotate the wet applicator with a strong downward pressure back and forth while the vacuum brush is providing support.
