Thousands of bristles reach down into the grooves of the record to remove dust. At the same time the brush removes static electricity, a big cause for pops crackles and other unwanted noise events. Quick and easy to use, requires no liquid, just a few rotations around the record before each play and its done. The carry handle folds under to protect the bristles while not in use. The brush has an aluminum body (not plastic) so that the static electricity can discharge through your hand and then eventually to "earth ground".
