Ultra-Pure Trombone Slide Lube - Now Called Alessi Formula - 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. Used and endorsed by Joseph Alessi, Principal Trombone of the New York Philharmonic. See usage info for instructions.
Shake well before use. Wipe the inner slide with a clean cloth and swab the outer slides before each application. Apply a 2 - 3 inch (5 - 7 cm) stripe per slide tube at the stocking end. Spread evenly up, down, and side-to-side one slide at a time. If the slide begins to feel stiff, apply one more drop per tube or clean slide and reapply. No water mist needed (or very little mist). Apply fresh every day or two for best results.
