| Re: Some stuck stuff on my trumpet... I agree that the best approach is to take the horn to a repair person. Especially for the slide, which can easily rack up more repairs getting pulled out wrong. For the bottom caps, if you insist on DIY, I have two words
Strap Wrench
They are readily available at most hardware stores and they won't mar the caps. Also good for chrome plumbing fixtures and other pretty stuff.
Just my $.02 - YMMV |
