I've read that people had some problems by breaking the lens coating with their cleaning solutions. So far I've been using an alcohol free generic cleaning solution, which works. Though I am still worried that I am damaging the lenses in some way over the time. The official site doesn't list any useful information about which solutions you can use and which not. A microfiber cloth isn't enough to clean off the fat from your fingers or eyelashes.
