The cleaner is fitted into the socket (8) of a power jig saw (9) and comprises a collet (3) screwing into a head (2). This has a spindle (1) fitting into the power unit, the reciprocating movement being imparted to it. The collet has seven holes, each equipped with an individual needle (5). Over each needle is placed a roller and, over the roller, is a spring. The reciprocating motion vibrates the needles which are free to be displaced individually and take up the shape of the surface (A) cleaned.
