I use this grease on the tuning slides of my trombone and euphonium, and it is a wonderful product. It only takes a tiny bit of this grease to make the slides work smoothly for months. There is enough grease in the little pot to last for years and years. Some other products are difficult to wash off from hands after application but I haven't had the problem with this grease. It also smells nice like all La Tromba products that I have tried.
