Clear Away The Throat : Like your own throat, the cleaning of throat plate is always necessary. So the lint has to be wiped off every time you start and finish the sewing.

Keep The Body Clean : Though it is not related to the performance of your domestic sewing machines, the body of your machine must be kept clean. A dirty exterior of the machine becomes greasy when it comes in a direct contact of moist and oil. Use a dry piece of cloth to wipe the dirt. If some drops of machine oil has spilled on the body, use a bit of detergent to clean it.

Service Circle : No matter how much careful you are about its proper cleaning, a domestic machine always needs a frequent servicing by a professional. So there is no harm if you get this done, once in a year.
