Cleaning a Muse headset between users for hygienic purposes?

Curious what method is best for cleaning a Muse 2016 or Muse 2 headset between users?

I have seen some people suggest a damp cloth with a little bit of soapy water, but I wonder if a 50% alcohol solution would be a better / cleaner method? Would the 50% alcohol be caustic to the sensors? Assuming no excess water would leak into the actual hardware?

At a conference demo recently, I used Wet Ones brand antibacterial wipes (in a pop up dispenser). Seemed to work well.
