First, we start washing the window with a solution of biodegradable glass cleaner concentrate and water. This step loosens soil and cuts grime.
During this step, we can also determine if the window has “stubborn dirt”; things such as bug goo and plant residue.
Next, if necessary, we scrub the stubborn areas with steel wool or scrape with a professional scraper.
After the window has been cleaned and the dirt is “floating” on the glass, we squeegee off the water. Squeegees run the majority of the water off the window and leave a small amount behind.
This is the secret to that streak-free look.
We then go over any areas of the glass that needs a touch up using a microfiber cloth.
When the window is clean, we use an absorbent cloth to clean the window frames and sills.
