Ultrasonic cleaners
I see ads for ultrasonic cleaners popping up on my Instagram feed. A quick check with Gemini et all says that they’re safe to use with high-end acetates and lenses but somehow I am not sure. Hence reaching out to experienced eyewear veterans here:
Are they safe to use with sunglasses and optical glasses where we have coatings and frames like JMM, etc., where you have acetate, titanium, and others with gold and silver? What about the impact on the lenses and coatings?
I currently clean my lenses with distilled water spray and use a soft tissue /microfiber cloth to dry them. For acetates, I use a microfiber cloth for just wiping them at the end of the day before storing them back.
