Can I use sewing machine oil on my trumpet?

Question

I need to get some brass oil... the buttons are sticking. But I can't get any for another week and I need to practice daily to keep up with my class. Will sewing machine oil (the kind to oil the needle's machinery, etc.) work just as well? Or will I really be harming the instrument?

If I can't use it, I can live with it.

Please, I want only answers from those who know what they're talking about =] Most helpful answer gets full stars!

Answer 1

I play the flute, and I use `Singer' oil to oil my buttons.  Works fine for the past 10 years.   But I think you better double check with trumpet players.  :)

Answer 2

Do not use sewing machine oil, it will render your valves inoperative.  Remove your sticky valves, wipe them off with a soft cloth, spit on them and reinstall.  It isn't as good as valve oil, but it will work in a pinch.  There really isn't a good substitute for valve oil.  Light oils like sewing machine oil, WD40, Marvel Mystery Oil, gun oil, kerosene, etc., just aren't light enough.  Moreover, they interact with your saliva and congeal into a sticky goo.
