3 T. liquid dish detergent (I used Dawn)
3 T. household ammonia
1 qt. all-purpose rubbing alcohol
Combine above ingredients in a one gallon container. Finish filling container with water. Makes one gallon.
NOTE: This is the second window cleaner recipe I have tried, and I really like it. I think it works better than Windex. I haven't calculated the cost, but I'm quite sure it is cheaper than buying it at the store and so easy to make.
