My mouthpiece cork keeps falling off- the cork isn't at all cracked, though.
The glue just seems to keep disolving- it's the weirdest thing ever.
I have reglued with rubber cement but it keeps disolving- is this my spit causing this? I think a little water gets into that tenon and sits while I play.
I really don't want to have to go through the time and expense of driving way out to the tech and getting this redone- I just need it to last for another few weeks and then all is well.
My main question is - What is making this happen?!??! I have never had this issue before!

The cork was probably installed with contact cement which usually holds up quite well. However, the ingredients in some cork grease products causes the adhesive to break down and you end up with a cork that just "spins". The non-technical term used in the repair field is "a spinner". My advice is to get it replaced and try not to overuse the cork grease and, perhaps, change brands.

Change cork grease brand to one from Doctor's Products, or Alisyn.
Also, some contact adhsesives are pretty useless, setting not into a firm 'rubber', but into a very gooey rubber.
If there are traces of grease on the surfaces to be glued, then no contact glue will hold.

Thanks for your help. I think I am just going to have to get a new cork- I keep trying to glue it, but the cork is probably full of grease. So THAT'S what's turning it to that nasty goo...
I just have to get through a couple more concerts/rehearsals then I will send it off.

You could also try "plumber's tape" as a temporary measure. A few turns will hold the cork on and act as a lubricant to facilitate putting the mpc on.

Ooooh... EXCELLENT idea. Thanks! I'll got get some today- that's been the issue- the cork is staying together and not breaking, but it keeps coming loose when I play and I am SURE that I am going to rip it to shreds while taking the mouthpiece off the barrel at some point.

Cork grease dissolves contact cement over time.
Use paraffin wax, rub on new installed cork after cement dries.
Wax keeps grease from seeping through cork much longer.
Just a little secret.

The term "contact cement" seems to mean different things to different people. To me, "contact cement" means the adhesive that has conventionally been used to attach "formica" to kitchen counter tops. You apply some to both articles to be attached, leave it sit for awhile and then bring the two articles together. The cement really "grabs" and attempts to readjust them are futile. I dont' consider "rubber cement" to be genuine "contact cement." It is applied in a similar manner but is mostly used for temporary adhesion of paper products. Nor do I consider hot glue to be true contact cement. Sorry if my views are not shared but the term "contact cement" ....to me....means a very specific type of adhesive.

I guess I misread. Rubber cement will never work on wood or plastic and cork.
Rubber cement should only be used for bonding 2 things rubber or very similar.
Contact cement has much more usage abilities. The same brand I use on corks I seen someone install floor tiles and carpet with in a gallon container.
A few other products will work but plain contact cement works best.

DAP contact cement works well - home depot or lowes if you're in the US

Technically speaking, there is no such thing as "rubber cement", VermontJM. Look again carefully at the label and you'll discover that it's Paper Cement. Paper cement is fine for sticking paper things, like photographs and party favors, together. For the tough jobs like mouthpiece and tenon corks you'll find Contact Cement gives far superior results.

Rubber cement dries and then the excess can be rubbed off around, say,a picture applied onto poster paper....the dried cement feels like little rubber pieces. You then flick them away, and no excess glue is evident.
Great for scrapbooks....useless for cork.

Would you really want to use an industrial glue instead of what techs use? I would worry that it would be harsher and more destructive to the mpc than what is usually used on clarinets.

Looks like I'm currently all out of rubber cement and since it doesn't exist any more I'm SOL...

Fantastic stuff!
BTW, many instrument manufacturers use a quite unsatisfactory glue to bond tenon corks, which is the usual reason for them falling off.

Mark, I couldn't get your link to connect for me :\ but, regardless of what we choose to call white rubber adhesive, and all levity aside, I don't think anyone'll find this stuff satisfactory for meeting the requirement of holding cork to woodwind joints or sax necks.
