Ultra-Pure UPO-CLASSIC Classic Valve Oil 50ml with Thicker Consistency Black Label

Works great for my antique horns as well as horns that are not so old but have been around the block a few times. I worried that it wasn’t labeled as non-toxic, but that’s just the company responding to legal requirements. It’s still the same formula! But if you ingest it then vomit it up and in doing so, pull it into your lungs, that is bad, but just smelling it is harmless. I called the manufacturer and checked with them. Good company! Easy to communicate with!

Ive tried several valve oils for vintage trumpets. I really like the performance on this one. Highly recommended.
