The Universal Zoom Spout Oiler has a convenient, extendable spout that is ideal for those hard-to-reach areas. Apply this high-quality, stainless ("Lily White") sewing machine oil to keep your machine in good running condition. This non-toxic, non-gumming, and non-staining lubricant will help prevent rust damage and will keep dust and dirt particles from forming in your machine. Once you have lubricated your machine, it is our recommendation that you use a scrap piece of fabric to sew on until the excess oil is gone. Whether you use your sewing machine daily or just occasionally, oiling your machine is important and will help extend the lifespan of your sewing machine.
