I don't have a RCM but I do use an Orbitrac for everyday cleaning. I have a used version of Steely Dan's "Katy Lied" that when played was noisier than I like. I gave it a good scrubbing with a MoFi brush and my DIY solution (4 parts distilled water, 1 part 91% isopropyl alcohol, half of an ounce of hydrogen peroxide, 2 drops of Dawn liquid soap){parts = 1/2 cup}. After scrubbing/rinsing/drying with microfiber towel, the LP is dead silent.
