Waynefia, my exprerience is that I used a lot more fluid for the same cleaning results when using the VPI 17's built-in brush than I do now applying the fluid to the DD type pads and then applying the wet pads to the LP. With the DD type pad, and applying the fluids to the pad not directly onto the LP, I'm making much more economical use of the cleaning fluid for superior results. As to using too little solution, when using the DD type pads, my experience is that as long as I reasonably saturate the pad the fluid amount applied seems to work out pretty well for me. With the VPI 17's brush, I was always concerned to have plenty of fluid on the LP when those vinyl bristles started their trek around the grooves, so I may have just used fluid more than necessary in that combination.
