The latest version of FactorLib (1.8) has a function to remove all the Expression Pedal settings. While this wold require a USB connection to a computer, it's a fast and easy solution and has been working for me since 1.8 was released.
I also agree that clearing the ExpPedal settings manually can be somewhat of a pain, so I wouldn't mind seeing a function added to all the Factors to clear all the ExpPedal settings, as we can now do with the HotSwitch on Space.
Definitely +1
