Couesnon Saxhorn or baritone from (estimated) the 1950's, no noticeable issues Īs my oldest instrument is also in one of the best playing conditions, I don't believe age is the determining factor for red rot.

Mahillon Saxhorn or Baritone from (estimated) 1927, only thing I noticed is some spots where the nickel lacquer is coming loose Couesnon cornet from 1908, a tube is leaking and a valve is missing the top spring, but apart from that no other issues

Couesnon cornet from 1902 in excellent playing condition (except for the corks on the top valve-caps) That said your red rot shows that the lacquer is already damaged to you might as well scrub/polish the spots and reapply lacquer.I must admit I am not exactly sure what red rot looks like, but have seen pics of it on the internet and I have not thoroughly checked my instruments, but I own several instruments that are quite old and neither of them has any issues concerning red rot (I think). Soap won't damage the lacquer, but scrubbing might.

What do you think of cleaning such an instrument soap? Is this going to damage the lacquer or material? However the brass still has to be polished and the lacquer needs to be reapplied. Isn’t it going to damage the instrument?įrom what I can find chemical cleaning looks like they use a mild acid and chelatior (like citric acid or EDTA) to etch away some of the red rot. What do you think of chemical cleaning? It sounds dangerous to me. Water could get here for a number of reasons from fog mist to moist hands, it does not have to be saliva only. Your brass was not scraped off and the spots are indeed a result of dezincification. Instruments are made from solid brass, this is required as a stiffer metal like brass is required to have good sound quality. How do I identify dezincifiaction correctly? Can it be seen on those pictures? (most important question) Brass Instrument: Dezincification or just scrubbed off?
