To evaluate aerosol glass/surface cleaners for vertical adhesion to glass surface.
A large glass window was cleaned using Windex from SC Johnson to ensure uniform clean surface. Once dry each of the test aerosol products were sprayed for 1-2 seconds onto the surface. A timer was started to determine the time the cleaner took to travel 1 foot (30 cm). A second observation was made to see how much movement was achieved for the products for a total of 2 minutes. At the end of 2 minutes the distance traveled by the product was recorded.
For products that need more than 1 minute to travel the 30 cm, time will be recorded as greater than 2 minutes and receive a score of excellent. For products that run down the entire length of the window (4 feet) in less than the 2 minutes, the distance were recorded as greater than 4 feet and will receive a score of poor.
Observations were made using the following:
|Time rating (sec)||Rating||Distance Rating (foot)||Rating|
Both products had good to excellent vertical cling as determined by the length of time needed to travel one foot and how far the sprayed product traveled in 2 minutes. The table lists the time and distances for each product.
|Product||Time 1ft||Rating||Distance in 2 min||Rating|
|Foaming Glass Cleaner Clorox||108 sec||2||37||2|
|Foaming Glass Cleaner Windex||108 sec||2||45||2|
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Brand Buzz Clorox Foaming Glass Cleaner was the most effective during glass cling testing.
