I used to much LYRA SPT on a Hana SH & the diamond fell off. I was listening to some 45 RPMs & didn't wait the 10 sec. ( I read that after). Always read the directions first.
I use Last Stylus cleaner & Stylast Stylus treatment, works great. I've used it since the early 80s. I just brush also but the Last Stylus cleaner gets it really clean. I still use the Hana, it was rebuilt by Soundsmith.
