This stuff is magic. I found everything I tried left smears on my telescope lens, even my camera lens cleaning equipment. I don’t know if it’s the coatings that cause the problem as I have no problem getting my camera lenses crystal, even on my vintage lenses. I gave this a go not really expecting much but to my surprise, IT’S FANTASTIC! A quick squirt and a swish around with a microfibre cloth and my lenses are more transparent than a Tory promise. I’m not worried about damaging coatings from having to over-polish, it’s just a quick wipe and I’m away.

Fantastic- THE best money can buy. Super efficient, doesn’t harm multiple coated Spectacle Lenses in any way . Mega economical in use - last an eternity.
I use it on a pair of very expensive Glasses with multiple film coats - 5 years use - Lenses still perfect- and always CLEAN!
