You might consider an ultrasonic glasses cleaner. They are pretty cheap (around €50), and clean without touch.

Thanks, I’ll check that out. But otoh it’s another thing you’d have to carry around.

I‘ll also try buying glasses online as suggested elsewhere. I do that with contact lenses already (dailies for when I’m on stage).

I've had good luck with eyebuydirect, and have heard some good things about Zenni too.
