Trial Purpose:
To evaluate aerosol glass/surface cleaners for vertical adhesion to glass surface.
Date Run:
01/29/2018Experiment 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.
| Product | Time 1ft | Rating | Distance in 2 min | Rating |
| Foaming Glass Cleaner Clorox | 108 sec | 2 | 37 | 2 |
| >120 sec | 1 | 27 | 1 | |
| >120 sec | 1 | 27 | 1 | |

| Foaming Glass Cleaner Windex | 108 sec | 2 | 45 | 2 |
| 112 sec | 2 | 37 | 2 | |
| 120 sec | 3 | 30 | 2 | |
| Product Average | 2.3 | 2 |
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
Brand Buzz Clorox Foaming Glass Cleaner was the most effective during glass cling testing.
