Monster Oil Classic Tuning Slide Grease is a fully synthetic, food-grade, non-lanolin lubricant. This thick, odorless, and temperature-resistant grease will keep your tuning slide working just the way that it should.
Professional trumpet players Thomas Brown, Joel Baroody, and Chris Lane established and developed Monster Oil. Knowing exactly what was needed valve and slide oils, they tested their products with some of the best brass musicians on all brass instruments.
