Hi Micha, Thanks for the invite. I do have a question about window washing. If I were cleaning a roof with gable or high windows. could I use the type of Window cleaner that you put into a garden hose attachment and spray onto the window from the ground. Would this be OK or would the windows streak.

Using the products like the windex outdoor spray won't leave you with perfect results, especially if you're in an area that has hard water. It will be better then simply rinsing with water - but I don't think the results would warrant being able to charge the customer for an exterior window wash.

If you wanted to add windows as an upsell, you could do this pretty easily with a water fed pole setup. With this method, you purify the water removing all the minerals that leave hard water stains. This ultra pure water actually pulls the dirt of the windows and rinses it away. The water is delivered through the water fed pole - which essentially is a pole with a brush on the end with flow thru jets. The pole has a hose running along the outside or thru the middle of the pole. With this method no cleaners are used, just the purified water. This method does not require a squeegee as the water dries spot free.

This method allows you to clean windows upto 5 stories (sometimes higher) from the ground using no ladders, no lifts and no ropes. I have a 60 foot carbon fiber pole that weighs less than a gallon of milk.

In many cases the WFP cleans the windows cleaner then a squeegee and soap can.
