Normally, plain water can clean lightly soiled windows; but if you put off washing your windows until they’re really dirty, you’ll need something more potent.
The best glass cleaner is one that works fast and removes grime with a minimum of help from you.
Are newspapers good for cleaning windows?
Over the years, there have been many opinions about which window wipers work best. Professionals do their wiping with natural-sponge applicators and rubber squeegees. Some purists feel the job is unfinished without careful application of a good chamois leather. Yet others swear by yesterday’s newspaper.
In a Consumers Union test of newspaper used withan effective commercial cleaner on heavily soiled windows, it was found that newspaper is not very absorbent. It takes a fair amount of wiping and rubbing to clean and polish a window with it. Newspaper also blackens hands and leaves ink smudges around window mullions.

Among the usual ingredients in most glass cleaners, none pose any problems for the environment. None of the cleaners contain phosphates, and none of the aerosols contain ozone-depleting propellants.
