[sci.electronics] Tactile Keypad

Last year I mortally (back then it seemed) killed my HP 28S
calculator.  But last night while cleaning out my desk drawer I had
an idea of popping it open.  After breaking a lot of internal
plastic and glue I found out that the tactile keypad had some
scaling/corrosion on the back(ground?) of the pad -- by accident
I had messed up the calculator in the first place by having the 28S
and a banana in a bag which I forgot about -- the banana got
flattenend and the key's were covered in banana.  I also noticed a
oily film on the top of the keypad...

Now, I'm about to go out and get some contact cleaner and see if
I can get this to work again, but besides that - any recommendation
for getting this HP to work again?  The circuit board is fine - I
got it to turn on...  Anyone know if I can order a replacement 
tactile keypad from HP?  

Any ideas/comments/criticisms about bananas/addresses/etc would
be appreciated
