The non-woven cleaning material is glued onto a glass-fabric base. This makes POLICLEAN discs suitable for use in face-down grinding. For coarse cleaning work, e.g. removing paint, scale, heat discolouration, rust and adhesive residue. POLICLEAN is a coarsely structured, abrasive, non-woven cleaning fabric that was developed from a special combination of synthetic fibres and abrasive grain.
