Piston Valve Oil for trumpet

This oil was developed by British trumpet expert Will Spencer. It contains an additive called PTFE. PTFE, already used in products like non-stick cookware and dental floss, is one of the most slippery substances known to man. The difference it makes is really unbelievable. This oil also contains a special anti-evaporative agent that makes it extremely long-lasting. Works great on both piston and rotary valves.
