Noisy rollers and clicking pivots are a thing of the past. Ultimax Pivot and Roller Lubricant is an amazing sticky oil that grabs both surfaces and traps in air bubbles, creating a thick, air-packed liquid bearing surface that takes up space in key mechanisms. This liquid bearing surface allows keys to move freely without noise even when there is excessive play in the mechanism. There is nothing better for silencing rollers and key pivots. For large instruments, use thinly coat key rods when reassembling the instrument.
