Hi
Unfortunately Cisco do not have any guidelines for disinfecting a Touch 10. For regular cleaning use a microfiber cloth or a soft damp clot.
>From my opinion any isopropyl alcohol/ disinfectant wipes while may be ok on the glass, but on the plastics, long term use may cause damage.
Suggest maybe using proximity to start calls from laptop or mobile device if possible, thereby reducing touches on touch 10 surface.
Having said that where do you stop? Lights, chairs, tables, door handles....
Thanks,
