@Gigantor - I thought I would actually add a poll. Fairly close to the top of the thread. Hope it might be of use, I can delete it if you’d rather I did. No worries either way
I’ve used these dry for over 40 years.
It’s not a brush or a cloth it has fibres and lifts the dust line with a tilt of the wrist.
Never use it wet though.
I think DECCA won some award for developing a micro carbon fiber brush.
I have an Ortofon Red brush on one turntable and a velvet brush on another. I’ve seen articles from reputable places claiming carbon fibre damages vinyl - hasn’t stopped me using it though.
I have that same brush, except mine has German branding, so is labelled “Teldec”. I use it for the record, and Stylast cleaning fluid for the stylus, before every LP side that I play.
Bought this in 1976, use it every time, never used anything else. You can tell it’s age from the ‘patina’ …or maybe its just grubby! Never attempted to clean it.
