I have used the following window cleaner for years. It's a homemade recipe and works great!
You will need:
1 gallon container (I use a 1-gallon Rubbermaid container shown above), Ammonia, Liquid Detergent (Dawn), Alcohol, blue food coloring and water.
In the 1-gallon container add:
1/2 cup ammonia
1 tsp. liquid detergent (I use Dawn)
1 pint (2 cups) of alcohol
2-3 drops of blue food coloring
Then fill the container to the top with water.
Close lid on container and mix liquid to combine.
Fill spray bottle with this mixture for a good window cleaner!
