Inside or outside?
Hire it done - especially if you have a multi-story house.
I suggest a vinegar/water mix and wipe it with a microfiber cloth.
Use Windex but wipe it with newspaper instead of paper towels, the newspaper doesn't leave any streaks or lint!
For the inside I do the same a TheHoneycombHome using Windex and newspaper.
Outside I use this mixture:
1/2 bottle of Jet Dry rinse aid (or approximately 3 1/2 ounces)
4 Tablespoons rubbing alcohol
1/4 cup ammonia
1/4 cup dishwashing detergent
2 gallons of hot water
Squirt water on the windows and using a long handled brush scrub and then rinse.
