Things You'll Need
Instructions
Lay several newspapers over your work surface. Draw a rough sketch of the machine with all the metal parts attached. It doesn't matter if you can't draw; this is just to help you remember where each part goes when you're done. Alternatively you can take a digital photo.
Dip an extra soft paint brush in brass cream cleanser or silver cream cleanser and rub a thin layer of the cleanser over each silver or brass part. Allow it to sit for five minutes. Wipe it off with a damp cloth.
Remove the lint from the bobbin case and from under the machine. Attach a small hose to a hand-held vacuum to suck out all the dust and debris from inside the machine.
Soak a soft cloth in kerosene. Lift the faceplate and wipe down under this area with the cloth. Locate the metal feed teeth and wipe them down with this rag. Wipe off the excess kerosene.
Oil the machine parts that actually touch one another inside the machine with sewing machine oil. Blot off the excess with a lint-free cloth.
Dab a lint-free cloth in car polish and rub it in to the surface metal of the machine, giving it a proper polish. Buff with a dry rag.
