Store your sewing machine under a dust cover at room temperature in a dry place. Use only new, high-quality thread to reduce interior lint buildup, and regularly unplug the machine and dust inside the bobbin case with a soft cosmetic brush. Lubricate the bobbin case with drops of sewing-machine oil; check your manual for instructions beforehand, says Becky Hanson of Singer Sewing Company. Then run a piece of fabric scrap through the machine to remove residual oil.
