OK, I am going to try the half alcohol/ half water solution. Thanks!
You won't be sorry. It is a gentle but effective cleaner for glass, plastic, enamel, etc, etc. As an optician, I used it to clean patients' lenses because it was safe for coatings (antireflective, UV, etc) and would not scratch. Any optician worth their salt can tell you that you should never use Windex on your lenses, so why should you use it on your monitor or other plastic or glass surfaces when their is a cheaper alternative that works as well or better?
Once you have tried it on a window or mirror or your LCD, you may want to make up a second spray bottle of the solution with a little Oil of Wintergreen or Oil of Peppermint added. It's great for cleaning countertops, stove-tops, bathroom surfaces, etc, and the essential oils leave a light fresh smell. The oils are pricey, but you only need a little dash in each batch of cleaning solution, so it will last a very long time. The water/rubbing alcohol solution not only cleans, but it helps kill germs, and it leaves no soap residue for more germs/molds to feed on. Best of all, it is really inexpensive. Go to your local pharmacy or health food store to pick up the essential oils and buy the biggest (usually the cheapest per unit volume) bottle of isopropyl alcohol they've got. Don't pay $$$$ for the Shaklee cleaning products (mostly water and alcohol anyway) - make your own and keep your money.
For those of you with access to methanol, do not substitute. If you're going to use this cleaning solution, use isopropyl alcohol and protect your health. Ethanol wouldn't be bad, but if I had ready access to food-grade ethanol, I wouldn't be cleaning windows with it. I'd be mixing it with wild blackberry juice.
