I believe that would be fine. personally I’m even more thankful for my waterproof OtterBox iPhone case. I just grabbed a cotton ball with alcohol and wiped it down. Hubby took the 99% pure electronics alcohol we have and can clean all the contacts and ports.
On the whole hand sanitizer thing. The standard isopropyl alcohol we buy at Sam’s Club is 91%. You can buy a gallon of sterile Livestock OB lube for about $13 off Amazon. OB Lube is basically the same base as purel but significantly cheaper. I have it for the imminent lambing anyway. So I’ll be mixing my own hand sanitizer. And for longer term a friend sent me this:
FWIW Our county was a major supplier of moonshine during Prohibition. The county Sheriff even helped load the railcars that took it to Chicago. I personally know of at least 4 stills in the county, licensed commercial ones, plus a number of folks with small stills used for concentrating herbal essences. We have a lot of fruit growing. I am sure that we will not be lacking in both drinkable and cleaning alcohol for long.
