I’m down to my last clean pair and I’d love to not have to buy a ton more of these down the line. They’re essential for any time I end up at a music-centric event, or really most events that include music. I’ll be scrolling through the earplug recommendations in this community too
If you must I use a little bit of bio-degradable all-purpose cleaner from ZEP, and then wipe it down again with a damp cloth; however, I’ve also found that the older single-use ear plugs don’t work as well, so do try to get a proper pair of re-usable ones.
I’d be careful using cleaners. You probably don’t want that stuff in your ears.
On top of that, trying to clean and reuse disposable earplugs can cause infections regardless of method. It’s better to invest in a reusable pair like loops.
Ofc, it’s a cost/benefit thing. Even though most of it’s gone with the wipe down, some of it might remain and then your ear canal could get infected if it disrupts production of ear wax; however, if you can’t sleep without them, well, sometimes you gotta do what you gotta do.
A better answer would be to get something else
