If there are green spots all over the place, honestly.....have a tech chem-bathe the body. This will likely cost between $50-100, since it requires all keys to be removed, then later reassembled. Yes, you could chase it with Brasso if you want, but it won't get anything INSIDE the body tube or bow, where there probably is something.My old Zephyr has many spots of greenish corrosion (oxidation? not sure) on the body. How do I remove it without damage? How do I keep it from returning or spreading? Thanks.
Too funny! Seriously though, if the horn hasn't been disassembled in a long time the chem bath is the way to go. That way the tech can clean and oil the rods and adjust the regulation at the same time.Hell, I thought everybody was paying extra for a horn that looks like that nowadays.
