Hmm, interesting point about the oleophobic coating...makes me wonder, would toothpaste cause similar issues on eyeglasses or camera lenses? Seems risky to test it out—anyone tried it and survived without regrets?
"Seems risky to test it out—anyone tried it and survived without regrets?"
Tried toothpaste on my glasses once when I was desperate (don't ask, long story involving camping and marshmallow smudges). It sorta worked—cleaned them up nicely—but left tiny scratches after a few attempts. Definitely wouldn't risk it on camera lenses, they're way more sensitive and pricey... Stick to microfiber cloths and proper cleaners for those!
I've heard toothpaste can actually buff out minor scratches on watch faces or phone screens, but glasses lenses might be too delicate for that. Did you use regular toothpaste or one of those gritty whitening ones? Because the abrasive stuff is probably what caused your scratches... Maybe a gentle gel-type toothpaste would work better? Still, I agree—wouldn't dare try it on camera lenses or anything expensive.

Haha yeah, learned that the hard way myself... RIP my old sunglasses. Did you manage to salvage your lenses at all, or are they toast now?
Haha, ouch... sunglasses are one thing, but lenses? I'd be way too nervous to even try. I once used toothpaste to buff out a scratch on my phone screen—worked surprisingly well, but it left this weird cloudy patch if you looked at it from certain angles. Definitely wouldn't risk it on anything pricier than that. Did your sunglasses end up cloudy too, or was it more of a scratchy mess?
