Cleaning windows with vinegar and newspaper can save you a trip to the store plus help get rid of newspapers that are laying around. Put equal amounts of vinegar and water in a spray bottle. Crumple a single sheet of newspaper to soften it, this will make it easier to handle. Spray the window with the vinegar solution then rub the newspaper in a circular motion. Now wipe the window dry with a clean sheet of newspaper. This works best with windows that are slightly dirty.
