How long do you think it should take to clean two full sliding glass doors and 8 large windows? I’m talking about start to finish, sparkling, no streaks no spots, clean? I’ve tried using newspapers (make sure you wear rubber gloves or you will get ink all over your hands and it still leaves streaks). I’ve tried using a professional cleaning tool with the sponge scrubber and squeegee. I still ended up with at least one streak on several windows. I finally decided it was best to ignore the streaks because getting perfectly cleaned windows was an impossibility. Then I found this pin from 33 Barefoot Lane.
Here is the cleaning solution:
1/2 gallon warm water

1 Tablespoon liquid ‘Jet Dry’ (You can purchase it HEREhttp://ir-na.amazon-adsystem.com/e/i...1&a=B001SQ1E2S.)

2-3 Tablespoons laundry detergent (liquid dissolves easier) or dish washing soap
Mix all ingredients above. Spray windows down with your hose. Wipe or brush onto windows, then immediately hose off your window. That’s it! You are now done. The remaining water will sheet off. No towel drying is needed.

LOL, sorry for such a giant post. I have no clue what I did, but most of the 3 ingredient recipes using the Jet dry were this with varying amount of detergent.

I don't have the formula as I really like using "Rain X" found in the automotive section for use on car windows.

Thank you. I am going to try this myself hopefully this week-end
