@antinn Hi Neil, The Brush is now inspected as advised and what was discovered was way beyond what was suspected to be the findings.
Note: The Brush is only removed from the sheath Bristle Protector for a few seconds at a time to clean LP's having been cleaned using the PAVCR manual cleaning method for a LP, a LP can be cleaned mid play, depending on what the Stylus is doing with contamination affecting the sound. The Brush has had about 300 uses since the PAVCR has been adopted. It is not possible to recollect how many uses were carried out between when the Brush was purchased in early 2021 and my first use of the manual cleaning method, which I believe commenced in spring 2022.
I have today witnessed substantial fluoresce particle count per Inch Square of approx' 50 - 100. I feel quite confident the Brush was quite contaminated prior to the new vinyl care adopted in 2022.
More importantly, I am feeling I have got back on track for my preparations for the Stylus to become a betterment. It looks likely I am soon to have a thoroughly cleaned ancillary to be the tool used whilst carrying out an important to myself discipline, that is not overlooked as an exercise, for being a part of using an Analogue Source in a audio system.
In my little world, the idea of not attempting to keep the Stylus in use, where at the interface for the Stylus being in contact with an environment that is not prepared to be most beneficial to it, is wasteful.
