How often, and how, do you clean your stylus?

Just for the record (!) the S_DUO does have a shallow distilled water bath that the stylus is immersed in. It comes with several rubber washers to make the sidewall of the bath, so that the height of it can support the cartridge with just the stylus and cantilever tip getting wet. The stylus is not supposed to touch the bottom of the water bath. As I said, very fiddly to use. However it does work (I posted before and after photos here) and I do believe it is ultrasonic in nature.

For the past few months, a DS Audio ST-50 when I feel like it, typically every 5 or 6 sides. Before that, a slice of Magic Eraser on a business card. If I can actually see anything on the stylus, I touch it first with the short- bristled Ortofon brush that came with my A90.

Humminguru s-duo. For the man with cojones. Never heard of it before now.

Inhale moderately, and BLOW!! Stylus is now clean.
