Our Teachers' Review
Valve oil is the single most essential maintenance item for trumpet players. Without it, valves become sluggish, noisy, and eventually stuck. Al Cass Fast is the industry standard — its thin, fast-acting formula keeps valves operating smoothly and silently.
Our teachers recommend oiling valves at least every other day, or whenever they start to feel slow. A bottle of Al Cass lasts months, making it one of the most affordable and important purchases a trumpet student can make. Keep one in your case at all times.
