I use RR fluids exclusively after trying most all of the commercial brands and several home-brews. RR proved the very best and for most of the reasons Jfrech notes, especially in terms of it leaving NO sonic signature. I do use a separate brush for the deep cleaner and one each for the two passes I give with the wash. It may be overkill, but I rarely have to give a second wash to any of my LP's after employing two "rinse" cycles using my VPI 16.5.
