@antinn Hi Neil
I am making an inquiry and I sense there is the best answer on offer from yourself, I hope you can assist with a guideline.
I have a Brush for cleaning LP's (Yukimu ADB-1) that has been quite a expensive purchase. What is really attractive about the Brush is the softness of the fibres and their never having become tangled at such a length.
These Bristles are so soft, I have been trusting with them to run the Stylus through them, which works for my purposes.
The Brush is now well used on cleaned LP's and has never been cleaned, I had once intended to Jet Blast it with distilled water from the Rinse Bottle used for Final Rinse when manual cleaning LP's.
My inquiry is, should a cleaning solution be used that is the same as used for the LP's, as much of what the Brush ends up being in contact with, is no different to what is to be removed from a LP as part of cleaning.
My main aim is to have a Purified Fibre on the Brush, bit also maintain the very attractive softness of the fibre. Losing the softness would not be a deal breaker for LP cleaning, but it would end its usage for the Stylus.
Note: I have a selection of cleaning methods for the Stylus, the Brush is usually used when a surface noise is detected through picking up a local fluff fibre.
