Wait for someone else here to give further advice, but I would say a dunk or two in distilled water could do it some good. On advice I received here, I finally got up the courage to dunk my 32SII, and it did the trick on sticky buttons. Your mileage may vary, and you are responsible for any damage to your calculator.
Remove batteries. Place the whole calculator in a glass pan of DISTILLED (not purified, drinking, tap, or other) water. Calculator should be open. While under water, press each button, swish it around some, and do it some more. Take the calc out of the water, and shake the water out of the calc, then repeat the process with fresh distilled water. Then, let the calc dry for a couple of days in warm air - Over a heater vent worked well for me. Reinstall batteries, and give it a try.
