Using this NanoLube Nano - Oil Anti - Friction Concentrate is easy. Just take the pocket oiler and use the stainless - steel needle to apply the oil to the areas that need lubrication. Make sure the surface is clean before application for better results. When you're done, keep the oiler in a cool, dry place. Avoid getting the oil in your eyes or mouth. If it gets on your skin, wash it off with soap and water. Check the oil level regularly and replace it when it runs out. This will help keep your equipment running smoothly.
