Review on 🔧 Al Cass Valve Oil: The Ultimate 2.0 fluid Oz. Solution by David Blackstock

I first got my hands on this valve oil 14 years ago when I bought a Selmer Bach student pipe and was looking for an unscented oil replacement that came with the tool. I've never had a problem with it and the valves in my horns have always moved freely. It has accompanied me at concerts, marches and jazz bands and has never been affected by humidity/wetness or lack thereof. I tried Blue Juice and walked away disappointed with the results so I'm definitely staying here even though the price has gone up about a dollar since I first bought it.
