Abstract
A bristle carrier for leaning a polishing apparatus comprises a number of radial slots into which sub-frames carrying bristles can be releasably mounted. The bristle carrier is used in place of a component carrier used during normal polishing, and is driven in planetary fashion over clothed polishing surfaces to clean those surfaces. The same carrier can be used, even when the bristles have to be replaced due to wear, by replacing the sub-frames having new bristles.
