Get at it with a quill brush or brass brush, then vacuum up what you've loosened. After that, depending on the case lining, you can use carpet cleaner or some other fabric solvent. Just make sure you dry the case thoroughly - set it out in direct sunlight over a few days. Always works for me.

If you are actually seeing green corrosion you are seeing the compound copper carbonate on copper metal, or alloy, or copper plated metal.......in which case you are talking about hinges or other metal parts. Is this it?

No, its actually on the cloth. I had the clarinet overhauled, so its all sparkly clean, but it left some green oxidation or something on the 20 odd yr old case.

Maybe it's time for a nice, new case.
With all the concern over mold these days, I wonder why people don't worry more about the grotty interiors of older cases. It would be nice if someone designed a case that had interior pieces that could easily be removed for thorough cleaning.

I'm sure you can find a new R13 case for a good price - my old R13 Eb looks pretty swish in it's brand new R13 case, the original case is too skanky for words and use.

Yeah, but those funky old cases have serious character!
All of my horns are at least a few decades older than me, and I try to preserve the original case whenever possible. If the inside is really that disgusting, I'll "reupholster" it, or even cut new foam inserts and cover those.
Hell, sometimes I feel like my zippered brown leather Selmer case is more valuable than the clarinet inside! ![[wink]](http://test.woodwind.org/clarinet/BBoard/smileys/smilie3.gif)

Slightly off-thread, but just a word of praise here for the good Doctor's case odor eliminator he's a sponsor). I have a Selmer Series 9 bass w/formerly skank-infected case, and the deodorizer really does work. No color changes or color bleeding that I could see, either.
Of course, this doesn't answer the thread's original theme, but sometimes a bad-smelling case can give you an IMPRESSION of skank that leaves when the smell does.

I first spray some Orange Clean spray, which cleans and is also a de-greaser and brush with a soft car upholstery brush. Then I let that dry overnight and finish with "The Doctor's Products" case odor eliminator. Works perfectly everytime.

Doctor's products are the best....but Febreze also eliminates odors. I must admit I still don't know what kind of gunk the guy is talking about. Why entrust your newly restored horn to a cruddy case interior.....or whatever else you will introduce in your attempts to clean it.

OK..here's the deal:
The case is fine...it is in good shape...it shows its age, but it rock solid, tight, and very usable. The clarinet has been beautifully restored by John Butler, it is a 1981 R-13, and the case is original. I would like to continue with the current case, due in part to its good condition, and in part to the fact that it shows that the clarinet is not new, and I think there is something neat about that.
The clarinet sat for a long time in the case, and in many places where the metal of the clarinet touched the case fabric, it has left behind green residue. John, has taken care of the clarinet itself, but there remains the green corosion type of residue in the various parts of the case.
The case doesnt smell or even look back inside. Just has the green still. So, is there a chemical or something that I can squirt on, that will remove the green stuff?

So....there was something on the metal or the fabric that corroded the metal of the keywork(or rings). One guess is that a prior owner tried to use silicone sealant to seat pads and that acetic acid is the culprit. If there is any chance of that you should consider re-lining the case....IMHO. I myself went through a period when I thought that original cases were great. I changed my mind but have a fair collection.

You can always keep the old case in the garage for nostalgia.
I bought a number of clarinets within the past year or two on the evil auction site. I had three of them (an R13, a Thibouville Freres bass [actually a Buffet] and a Bundy Contra Alto) rebuilt, and I treated them to new cases. I don't mind dealing with a clarinet and a case if they're in decent condition, but it doesn't make sense to me to put an exquisitely cleaned, buffed, and refurbished clarinet back into a filthy, musty case. That would be like taking a shower, and then putting on underwear that you'd been wearing for the past ten years. Actually, if the clarinet had been previously owned by another person, it's worse than that. It would be like taking a shower, stepping out, and then putting on underwear that someone else had been wearing for ten years. Ick.
You can get some nice cases economically if you shop around. I actually found a guy selling new, unused R13 cases on eBay.
I have to hand it to those of you rebuilding and reupholstering cases. From the cases I've seen, that's got to be a fairly complicated project.

Actually, I'm with Bryris on this one. If I bought a nice, old BT or CT and the case was structurally sound, I'd want to use it too.
But, unfortunately, I'm no help here. It sounds like the green spots MAY actually be color changes in the velour of the case rather than crud on TOP of the velour. In the interests of science, I just checked the case my high school horn has spent the last 45 years in, and sure enough, there's a green deposit in the case where the upper part of the bell rests. It's undoubtedly old cork grease that has somehow interacted with the metal in the joint ring and turned green as a result. The velour is matted, too, right?
You might try a little cleaning fluid in one tiny spot, to see if it does any good. What else would dissolve old grease without ruining the color of the velour? Unless some chemists out there have an idea or two (or professional dry cleaners, for that matter) I guess I'd say, "learn to live with it."
good luck with the horn!
