Blue Juice is a scientifically blended oil for all valved instruments, piston and rotary. It was developed by a Chemical/Lubrication Engineer who was also a Trumpet player. The primary objective was to develop an oil giving fast valve action and staying power to minimise the need for re-lubrication.

Less obvious Blue Juice has built in inhibitors to repel bacterial growth, and kill any that may have formed, especially when it is a long time between clean-outs. Blue Juice is also non-corrosive to all metals used in the construction of musical instruments. In fact, it helps keep instruments internally clean. A problem all rotary valve musicians are very aware of.
