Heijneker 26 Posted August 24, 2020 Right now I'm on vacation to sunny italy, I didn't bring my cleaning supplies with me, which I sorely regret. I did however, pack Opti-Seal and some cheap MF towels, since I used it as an interior glass cleaner with great succes before. My sunglasses were very nasty from sweat and sunscreen, and just MF towels weren't enough, so I used some Opti-Seal. Worked awesome of course, cleaned up perfectly. Later on, the glasses got as dirty again. I was driving so my girlfriend had to do the cleaning. She used solely the MF towel, but now they cleaned up perfectly! Later still, even a cotton shirt would do the job pretty okay, which is astonishing. I'm amazed, Opti-Seal also gives glass a really nice slick/clean feeling. TL;DR: Opti-Seal makes my super greasy/dirty sunglasses' lenses extremely easy to clean smudge free, and I love how it makes glass feel! 2 habs33 and LostVulpine reacted to this Share this post Link to post Share on other sites
