Glaude 1,615 Posted May 13, 2018 I use that sort of stuff : https://www.lenspen.com/ Works great (even the cheap one you can find everywhere). First you brush the inside to remove any debris that will potentially scratch the glass, then you use any cleaning solution for spectacles or screen with a microfibre cloth and in the end you finish with the lenspen carbon tip.
