How to get rid of unwanted particles, dust, dirt etc. at your cartridge stylus which might degrade the sound quality?
I am never using a brush, sometimes a zero dust jelly tool. Best is a special liquid like the Audio Technica AT 607 or Lyra SPT Stylus Treatment.
Using a small microscope enables me to clean the stylus by careful watching what I am doing in „the small world“.
I got a Lyra Titan i, which was one of the first promo Titan i s, not labeled but an improvement of the original Titan. Just look at the condition after using it for quite some time and the result of careful cleaning by the AT liquid under the microscope.
