MonsterOil Tuning Slide Grease

Nobody's favourite part of instrument maintenance. But it has to happen, so it may as well work perfectly and look good while doing it.

MonsterOil's slide grease is synthetic and non-lanolin — thick, long-lasting, and designed to hold a proper seal without breaking down mid-rehearsal. The kind of product that goes on once and stays there. The packaging is distinctive enough that it won't disappear to the bottom of a bag the way the generic tub always does.

Works as a cork lubricant for woodwind instruments too, which makes it genuinely useful across the whole case.
