Never cleaned an O2 sensor, but if they're already messed up, you can't make them worse. Hit em with some carb cleaner, see what happens. All you're out is your time

Gasoline is also a solvent, and evaporates at a pretty decent rate. Let them dry and you should be fine.

If you are determined to try to clean the O2 sensors, first use a 3 M product made to clean Throttle bodies and plates. It is not as harsh as the old Carb Cleaner spray. There is also a MAF cleaner you should look at because it is also more gentle. Don't clean the electrical portion of the O2. If that doesn't work, then try the gas procedure. Please let us know how it turns out.
