Candace and Barbara Sue; I have the same machine - how funny! I am donating mine. How have you cleaned, if you had to, the slide plates? Mine are blackside and have rust so am looking for cleaning options for them I do have Barkeeper's Friend but am leary of using it and removing the blackside finish. My case is in sad shape so DH and I are cleaning it up some but don't have enough time to strip it and refinish it.
