About record cleaning, the machine @lalitk recommended looks like a variant on the VPI 16.5. Much better than nothing, but not consistent with your investment in vinyl front end, IMO. I had one of the VPI machines - after cleaning with the VPI, my ultrasonic system removed as much grunge again. Difference in sound was even greater. Some unlistenably noisy records became pristine, high M-, if you can believe it.
The issue with record grunge is that even a tiny amount is unacceptable, since an analysis indicated equal portions of grease, diamond dust, and household dust (don't have the reference). That is just about an ideal industrial grinding compound, ready and able to re-shape your expensive, precision stylus into a blob. Using the VPI alone, one of my styli was utterly destroyed after about 1500 hours, vs almost new after 1000.
