It would be best to also purchase a shotgun cleaning rod. Apply the Wrights to a folded piece of paper towel (attached to the cleaning rod).
Wrights is water soluble, so it will clean out really easy.
I use this occasionally to polish my brass trombone slide.
I didn't have Wright's but I did have another brass cleaner similar to it. I took it to town on that bad boy, couldn't let him go. I cleaned the smacks out of that thing and the water went from reddish, to black, to green even...then afterwards I broke out the baking soda and lemon juice and did the same thing until that pipe was clear as glass...then the job wasn't finished there. I then applied a piece of paper towel to dry out the stem and BADA BING!!! Problem Solved!!!
