Stay away from this brush

The bristles of the brush are so hard that they leave fine scratches on the disc.
I can do it without any problems decelerate only with the brush, the plate on the rotating plate and let rest my LP12's continues to rotate while the plate.
And no this is not the case of the brush on the plate and I'm fine motor skills to use and capable of producing a disk brush, with my other Corbonbürste ego-creating indeed ;-)
For normal cleaning my sheets absolutely unfit
I'll take now as a hard brush if time at a flea market a plate dirt lumps so sticks in a groove that my Xiban not wegbekommt the dirt.
This cleaning process one sees behind the optical drive, but the pickup will not start at least through the caked dirt in the groove.
