ive only had it 4 days..is that a reasonable amount of time for the corrosion to start showing?Yes. Also normal for a lacquered horn on which the lacquer has become damaged.
Manufacturers put lacquer on because bare brass corrodes. If you buy an unlacquered horn, you just have to accept that you've bought a horn which will corrode. You can minimise it by wiping it bone dry inside and out after each playing.
I've never been able to understand the attraction of unlacquered horns - the lack of lacquer doesn't make any difference to the sound and they just look tatty far quicker.
Yes i just used the buttons as a quick fix job.I found a guy on ebay since then who sells lots of real pearls.I got some pink abolone pearls for my mauriat 64 soprano,looks and feels great.He sells,blue,red,green,pink abolones.Glad the BW is still going strong,i was pleased how the stripping job went on it,the bronze ul looks very nice.Keep blowing her and enjoy.I know how you feel Davey, I've never really cleaned saxes. Same with bikes. Been riding for thirty years, in all that time I've only ever washed one once. Prefer to just use the things, keep them in good mechanical order but not fret about the appearance. Just like the sax.
BTW, Davey, I've now got your old BW unlaquered alto. Has an aged look to it, plays great. Really great. You'll be disappointed to hear that I've removed the black buttons and put pearls in, though.
Is that a new horn of just new to you,. I wouldn't call it corrosion, it's patination in my view, It will take centuries to make any great impression on the integrity of the brass. If you don't like it clean it off and get some renaissance wax to slow down the patinationhi all....im attaching a couple of pics of my new P.Mauriat 66RXUL..it looks like it has bits of corrosion/verdigris on the body (about 7 in all) and the bell (3)..is this normal for an UL horn?
