BOHIN sewing machine oil is intended for lubricating moving parts so domestic machines run smoothly and quietly between services. This bottle contains 20 mL (2/3 oz) of clear mineral oil for routine maintenance of metal mechanisms in sewing machines and similar equipment. Apply a small drop only where your manual recommends, then wipe away any excess to help prevent oil marks on fabric. Keep the cap closed between uses and store upright to reduce leaks in your sewing kit.
