Ultra-Pure Trombone Slide Lube has a really wonderful glide on all types of slides. It lasts a long time and does not gum up or leave residues. It has a fast, smooth feel that you will love! Nicely water-repellent and can be replenished with a little water mist.
Just apply a few drops to each inner slide tube and spread it up-down and side-to-side, one tube at a time.
