Stylus Cleaner: RRL 9 vs. Audiotop

I have not used a liquid stylus cleaner in the past, just a zerodust and magic eraser. I am intrigued, however, by some of the reviews i have read about the RRL #9 stylus cleaner. Any first-hand experiences would be appreciated -- particularly direct comparisons with its pricier competition made by Audiotop. Thanks.
