Things You'll Need
Instructions
Use a microfiber dusting cloth or a car washing towel to clean off any large or small visible dust on the hand crank sewing machine.
Apply a gentle degreaser using a white smooth cotton cloth or old white T-shirt rag to areas on the sewing machine body where grease or oil buildup has occurred. Using a natural and non-toxic degreaser like Simple Green is best because it will be gentler and you don't want to ruin the finish on your machine.
Clean the sewing machine body using warm water with dish soap using a soft cloth or dish rag, paying particular attention to cleaning any spots that were cleaned with degreaser. Clean the hand crank sewing machine only in an environment and humidity that will allow fast drying, to prevent rust.
Use a cotton swab to clean any small areas--with degreaser or dish soap, or both--that need cleaning but are too small to be effectively cleaned with the rag.
Clean the wooden case and base for some hand crank model sewing machines using a higher quality wood cleaner and polish. Murphy's soap for wood floors and furniture works well to clean the wood cases.
