Ultra-Pure HEAVY Tuning Slide Lube is perfect for those loose slides that seem to slip over time. It’s also excellent for preventing mutes from falling out: simply apply a small amount of Heavy Tuning Slide Lube to the mute corks, and the mute won’t fall out or squeak when you place it in the bell.

This lubricant is clear, colorless, odorless, and nontoxic. It’s very long-lasting. You can wipe it off your fingers with a tissue or wash it with soap and water.
