Spencer's Snake Oil.
The NEW Valve Oil we all know and LOVE!!
Snake oil was developed by trumpet technician Will Spencer, previously sold under the Denis Wick brand until the the end of 2023
The 2024 formula has been improved! 
It still has the familiar silky feel, lasts longer than most other valve oils, leaves no residue, is odourless, and is not affected by extreme temperatures.
However, it is now even slipperier!
This new formula has already been praised by many top professional trumpet players, but it also works extremely well on lower brasses, and all rotary valve parts.
