for cleaning monitors, I use these little glass cleaner individually wrapped tissues for my glasses. Works well and don't have to worry about spraying your monitor.
use a glass cleaner? hmm I don't think you should do that, unless it says, its safe to use on LCD. Its likely the cleaner might contain something which might damage your LCD! Go to your local shop and see if they have LCD cleaners, thats the only way I clean my LCD!
