I am about to embark on a journey of sky observations/nature walks with grandsons and binoculars. It's a given that they are going to get dirty/smudged and will need cleaning. The binocular lens and coating both will be cleaned and therein lies the danger of scratching an objective lens and/or a coating or removing the coating.
So are there recommendations on cleaning kits, though hopefully not as dear as the Swarkowski (sp?) kit and necessary tools and tutorials on YouTube you would recommend?
I know this has likely been dead horse beaten in past posts, but as a new comer I lack the experience of trial and error which you have. So I hope to tap that knowledge without having to gain wisdom, the hard way, e.g. the "OMG" moment.
