Microfiber squares actually charge LP and disc media during cleaning. That's on top of the static charge generated from removing media from its protective cases or cover. CDs develop somewhere around 500~1,500V of "frictional static electricity", and ten times that for LPs.

To use just lightly brush the surface of LPs, CDs or other optical media in a circular motion. The brush employs the finest hard-to-find goat hair prized for its softness, just perfect for removing dust from LPs without leaving any marks.
