Use sewing machine oil and a soft brush to clean the machine. First make sure you clean the machine with a soft brush and a little water to remove the dust in the paint. No evaporust on the black slide plates they are blued like guns are. If the black plates are rusty you have to remove the rust then yes you can use evaporust but you will have to reblue the plates to get the original look to the black side plates. These plates have not been chromed but blued metal. I hope the plates are not rusted. Please post a picture of this machine so we can help you better.
