I'd be worried about lens smudges!Tough call. Nothing wrong with a good tease.

Dish soap and water ok not really it is water resistant, just a eye glass dust cloth
I put mine in the dishwasher on the top tray set to no heat drying. Cascade and Jet Dry. Does a great job. Just like drilling a hole in the iphone 7 gives you access to the headphone jack
Seriously I use a microfiber cloth and screen or camera lens cleaner or an alcohol wipe.
Everyday after I shower and dry off I use the damp towel, it cleans the phone back to the brand new look.
