If you want to be squared away – get this. Pro Shot Nano-Tech lens cleaner is ammonia- and silicone-free, and can be used on all lenses including many thermal imaging lenses. Once applied, the surface will resist dust and fogging, allowing your optics to perform to their full potential. Always use a clean cloth or bud to wipe. This product is brand new, so you will have to ask for it at your local store.
