Flexible effective antistatic brush, I use it before every listening: it avoids the major dust and premature clogging of the grooves and the read / diamond. The hairs do not fall and did not ruffle. However, very soft, do not press too: risk of scratching with hard angles of the handle. Do evidently not expect a miracle for vinyl dirty, found in flea or those you have not taken care of regularly. For these, you can use diluted dishwashing detergent or a little alcohol (70 °, more risk more damage than anything else) + cotton cleansing. And of course, never tap water too hard (demineralized water is ok). A neighborhood store you may find useful with a specific machine for the dirtiest disks (at least until all the grooves under the "crust").
