Simply combine one part alcohol and one part distilled water in the spray bottle. Making this screen-cleaning spray couldn't be easier. Other unpurified waters, like tap water or spring water, will leave an unwanted residue on your screens due to their mineral contents.

The key to this homemade recipe is the use of distilled water. Masking tape and permanent marker for labeling (optional).8 ounces 70 percent isopropryl alcohol (rubbing alchohol).

Keep one on your desk, one at home, and one for the road - and never overspend on glorified water again. For just a few bucks, you can make your own, equally effective screen-cleaning solution at home in large quantities.
