Homemade Windex

My husband is a big fan of Windex ammonia cleaner and uses it frequently. When I came across this easy recipe to make it at home, I got excited because it's a money-saver and I know now what is being sprayed on the surfaces of my home:

2 cups rubbing alcohol (70% isopropyl)
1/2 cup ammonia
1 tsp liquid dish detergent
top with water until you have 1 gallon of window cleaner (4 Windex bottles)

To make 1 Windex bottle:

1/2 cup rubbing alcohol
2 Tbsp ammonia
few drops liquid dish detergent
top with water

If you want it to look "authentic" add a few drops of blue food coloring until it's that electric blue you are so familiar with. No one will know the difference...
