Hi, I tried using Zeiss Lens cloth(little wipes) they have no ammonia but are alcohol based and left lots of streaks. Thought I would take canepoles advice - went to Wally world looking for Norazza wipe in Electronics-NO GOT never heard of (well IL what do U expect) Manager of dept says use what I use "Nice'Clean Electronic Cleaning Wipes" in Blue box. Safe for all monitors, screens etc. or only a vinegar based window cleaners.
