Well, ok... I have a Bruan shaver. You know how it has the dock station to clean it with that lemon like alcohol solution stuff?
The only reason why I mention this is because the drying fan inside of the unit broke on me a long time ago but I still use it all the time - but the alcohol has eaten away at the plastic on the shaver because it never gets dried off.
So had this not happened to me I'd laugh at the idea of alcohol eating away at plastic, but it happens especially if you don't dry it off. But this is over the course of like 3-4 years....
I've used disinfectant wipes on the AirPods - dried them off immediately. I use a piece of paper folded (sharp edge) to get inside the ear speaker area to get out earwax.
Fortunately, my 10+ year old Series 7 is in decent shape, but, the paint near the razor head has been eaten away by the alcohol.
Not surprised that the ethanol ate the Airpods. Not a great comparison, but, think along the lines of E85 fuel and how if the car is not equipped to take it, the fuel system and seals could be eaten away.
An option is to use lens cleaners for coated lenses, as they are made to go easy on the lens coatings.
Or, I will spray some multi-purpose cleaner on a microfiber (or paper towel when in a pinch) and wipe. Microfiber alone might be enough.
Big thing to help keep the gadgets clean is to wipe often, particularly after some heavy/sweaty use. Set a reminder in Reminders to wipe down the buds on some schedule (weekly, every other).
