This valve oil is some of the best I've used. It has odourless, clear and easy to apply.
I have mainly used this an Adams and Carol Brass trumpet, both of which have good valve blocks with great compression. So you milage may vary with older horns or student/ intermediate horns.
I found this to leave very little residue as compared to other valve oils I've used and so far I haven't had valves stick during a gig. When playing 5-6 days a week applying the valve oil twice a week does the trick.
There valve oil is odourless and doesn't stain clothes, bags or trumpets which is great. It is also easy to remove from any unwanted areas with a lint-free cloth.
Highly recommended!
