The Genius said it's okay to clean these with 70% alcohol solution, but upon contact the plastic began to melt. I bought these about 10 days ago, do you think I could exchange them?

EDIT: I should specify, the cleaning agent was laboratory grade 200 proof ethanol diluted to 70%/30% with distilled water. Clearly there's something other than water and ethanol in this solution.

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.

Doubt Apple will do anything about it.
 
It was a pure 70% EtOH/30% distilled water mixture from my lab, so it definitely doesn't have acetone or anything in it.

And it's not very interesting, it just melted the top couple layers of plastic and it roughened up the surface. Funny enough the roughness means they stay in my ears better than before...

Yeah my shaver looks slightly porous and rough near the top part. Interesting. As long as they're still usable - cool.

I use ethanol in my lab all the time, especially for some of the assays that I run, and for cleaning up my bench area. I’ve had it ruin my phone skins in the past, so I absolutely can see it ruining plastic objects. Skinomi replaced my iPhone skin, but I’ve since switched to tempered glass.

I’m glad you posted about this. I use 2-propanol for cleaning my ‘pods, usually wipes, but i’ll keep EtOH away for sure now. I hope you can reach a resolution with your own AirPods.

Yeah I'm not sure what else they put into the stock 200-proof solution, I suspect it's not just EtOH. I've never seen ethanol melt plastic like this, and I bet they put in small amounts of methanol or something to keep it azeotropic.

I use it to wipe down my bench as well, but one day I decided to wipe down my Eppendorf ultracentrifuge - it stripped the paint right off the steel. I just thought the Germans used a crappy paint but now I'm thinking the ethanol is to blame.

No it did not melt the plastic. You are mistaking a correlation with a cause.

You either used the wrong cleaner, or just noticed the damage (caused by something else) and attributed it to the rubbing alcohol.

It was 70% EtOH solution, and I didn't misattribute it. The white plastic literally rubbed off on my skin.

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).

Nice another 7 series owner! I’ve owned this model since mid 2000s when it was the 9000 model and lasted until 2012. Then got the 7 I have now - going strong. Cool. :)

To me, 70% alcohol solution would imply 70% isopropyl alcohol, not 70% ethanol.

Especially when used in the context of cleaning small parts.
This. The general understanding when people talk about alcohol for cleaning is 70% rubbing alcohol, not ethyl alcohol.

Of course, there’s no harm in trying to get an exchange. Worse come to worse is they would deny it. Nothing to lose.

Can You at least share a picture of your AirPods for the rest of the forum members to view? That would be fairly interesting given what you stated you cleaned them with.

What do you guys think of the Braun foil shavers versus the Norelco rotary shavers? I have a Norelco 5300 or something, and I find the independent heads don't provide a close shave. I've been meaning to try a Braun foil shaver but I'd like to get some firsthand opinions about them first.

I understand someone else mentioned a shaver, But I have Zero idea what a Norelco/Braun shaver has _anything_ to do with your AirPods being disfigured due to your own doing or why you’re asking about someone else’s opinion about a shaver? (Which is irrelevant), which also leads me to wonder why you won’t post a picture for others to see exactly what happened to your Airpods? That suggestion as previously made seems highly related to the thread albeit.

It's really not interesting, they look normal except for some swirling in the surface where the plastic melted. If you really want I could upload some pictures but IMO it's not worth it.
