I put a drop of Last stylus cleaner onto the brushy surface of my battery-powered Professional Stylus Cleaner, turn on the machine, lay it on my turntable platter, cue my stylus down onto the brushy surface, and let the machine deep clean my cartridge. I do it about once a week. Better fidelity...more everything...invariably results. The thing is, the cleaning machine vibrates to the point where it wanders around the platter. You gotta keep it secure & stationary with your fingers.
