Q: disinfecting

You don't.

Use an X-ray cassette bag meant for use in the OR.

Do a Google search using disinfect ipad

Apple says to only use water (no chemicals) and a microfiber cloth. Some of the links say use a baby wipe.

The iPad fits nicely in a gallon size ZipLoc bag. After use, you could discard the bag and then cover with a new one. The buttons and screen works when covered with the bag.

Hi Jonathan - and Tom - cameras can be sterilized with an anprolene gas sterilizer - do you think it would be safe for an iPad?

Thanks,

Charlie

90~99% Isopropyl alcohol on a microfiber cloth (slightly damp). You can use surgical gloves while doing this. Careful not the get liquid inside any openings. After this you could place the iPad in a clear ziplock bag.
