I recently purchased a Domestic 935. Lovely machine and clean everywhere except around the handwheel. When I took it apart to clean I couldn't believe what someone had done. Thick black grease on the handwheel and the belt. Had to clean it all out (what a job that was since it was so thick) and buy a new belt. I used Goo Gone Extra to desolve the grease. It works just fine now.
