The hunt eda record cleaning brush contains over 1,000,000 anti-static carbon fibres.
The fibers are in two rows with a static grounding pad centered between. The grounding pad supports the tiny carbon fibers and keeps them erect so they can dig down deep into the groove and extract trapped dust. Look at a record; it contains microscopic undulations inside the groove wall smaller than a human hair that the naked eye cannot see. This is how music is stored on an LP. And this is why fat pads will not do.
