Answer:
✓You should clean and oil your sewing machine depending on how much you use it and the types of fabric you sew.^ If you sew quite often and use fabrics that "shed" like velvet, then you will need to clean your machine much more regularly.^ If you are a light to moderate user, then you can clean your sewing machine once every few months. ^The rule of thumb is that if you hear squeaking or clinging and see build up, then it is time for a refresh.
