I know, you’d think not, right? Now, I’m not recommending this, I’m just telling a story from my idiotically young adulthood. I’d never do this now.
With my first ever set of pierced earrings, I was scared about getting infections, so I’d nightly squirt peroxide around the hole. When I was finally able to take the earrings out, I left them overnight in isopropyl alcohol. I knew nothing about pearl care and fragility. It’s a miracle I guess, but they stayed fine! I routinely cleaned them in alcohol. Maybe they held up because they were very good pearls? A gift from my best friend and her Mom, in 1972, about 4.5mm? I asked her Mom, “How do you take care of pearls?” She said they’re no special bother if they’re really good, just rinse them off and dry them. She was a dear.
I almost had a stroke when my sister told me “you know, you’re only supposed to clean them with gentle soap, and rinse them in filtered water...”.
( I had them for about 7yrs before I got my ears pierced, and wore them every day for 10 years. They were still beautiful when I lost them rafting in the New River Gorge. We were warned to take all jewelry off, wear no contacts, no glasses. So, I did take my wedding rings off and put them in the car, but forgot my earrings. When I remembered them we were already on the water, and approaching the first rapid. The guide said something like I hope you’re not in love with those earrings...
I had really tight cutoff jean shorts on, so I tucked them in the tiny front pocket. End of rafting trip - they were gone, ripped right out of my pocket. Devastating.)
