Outdoor Window Cleaner

It is not a simple thing to wash windows from the outside. Thankfully, this is an ideal cleaner for big outdoor windows when you don't want to use a ladder to wash themt by hand and for windows that are difficult to reach because you rinse and then let the windows drip-dry. Make sure you do this on a cloudy day.

Cost: $1


  • 2.5 gallon capacity or larger bucket


  • ½ cup dishwasher rinse aid, i.e. Finish by Jet Dry
  • ½ cup isopropyl (rubbing) alcohol
  • ¼ cup household ammonia either sudsing or non-sudsing
  • cup any automatic dishwasher detergent powder, i.e. Cascade Complete
  • 2 gallons hot water


  • Pour all ingredients into the bucket and mix well until combined. 

To Use:

  • You will need a hose with a good spray nozzle, some kind of scrubber (I like this one from Amazon) and a long-handled pole for windows that are out of reach.
  • Spray windows with the hose and that powerful spray nozzle, knocking off dirt, grime, and debris. Set the hose aside. 
  • Dip your scrubber of choice into the solution and get it totally saturated. Don't wring it out.
  • Scrub the window thoroughly in all directions, making sure you reach the corners.
  • Spray window again with clear water using the hose and a powerful spray nozzle.
  • Let dry.
  • That's it! Both the dishwasher detergent and rinse aid will create a "sheeting" action, to leave windows clean and streak-free.


NOTE: Before you ask about safety issues for pets and plants that might be in the way of this cleaner as it is rinsed away, I cannot say for sure one way or the other. What I know is that it has not damaged in any way anything growing in the area of the windows I've cleaned.
First, most landscape fertilizers contain ammonia. Next, the ingredients are greatly diluted in the 2 gallons of water. Then diluted again when rinsed away with more water.
Once the windows are completely rinsed I take time to hose off the deck, and for windows above plantings, I spray all those areas well to dilute any effect even further.
If you are concerned, please conduct your own independent research.
