Trial Number 5

Trial Purpose:

To evaluate aerosol glass/surface cleaners for vertical adhesion to glass surface.

Date Run:

01/29/2018

Experiment Procedure:

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
120 Excellent <1 Excellent
60 Good 1 Good
30 Okay 2 Okay
15 Fair 3 Fair
<15 Poor 4 Poor

Trial Results:

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.
