The demo for the Thunderon makes the process look quick, easy and effective.
https://www.sleevecityusa.com/Sleeve-City-Thunderon-Conductive-Record-Brush-p/dc-505.htmI see that the Hunt/DAK brush claims to remove dust from both the surface and inside the grooves.
Good word of mouth about the Hunt over the years.
It goes without saying that the record being used has first had a thorough wet/ultrasonic cleaning.
What I wonder is how long will the charge last on the fibers of these brushes.
When my original Audioquest-anti-static-brush was new, it worked so well picking up dust that I didn't need to use my Zerostat. Now the brush has no anti-static properties and I use it in combination with the Zerostat.
