<p>[QUOTE="fretboard, post: 5426152, member: 19765"]Nice, but is that bronze disease or verdigris??! I would drop it into hydrogen peroxide but no longer than 4 hours. Some will say distilled water but I doubt distilled water would work. The thing about using hydrogen peroxide is it will definitely change the color of the metal if you leave it soak for longer than 24-48 hours! Acetone? I don't think it will work but heck I've been wrong plenty of times on this forum! <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie8" alt=":D" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
