Trial Purpose:
To evaluate client requested products on the sixth supplied soil.
Date Run:
07/08/2004Experiment Procedure:
The three cleaners were diluted to 5% using DI water in 600 ml beakers at room temperature.
Nine preweighed titanium coupons were coated with ink from a Sharpie marker. The ink was applied first in a side to side manner and then in an up and down direction. Coupons were then weighed a second time to determine the amount of soil added. Three coupons were cleaned for about 2 minutes using a Gardner Straight Line Washability unit. Three coupons were placed into a Gardner Straight Line Washability unit. A Professional Painter's Rag was immersed into a beaker of the cleaning solutions and then attached to the cleaning sled. The cleaning unit was run for 75 cycles (~2 minutes). At the end of the cleaning cycle, coupons were weighed again and efficiencies were calculated.
Trial Results:
One of the three products removed over 85%. The table below lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
| Cleaner | Initial wt | Final wt | % Removed |
| M Aero | 0.0019 | 0.0002 | 89.47 |
| 0.0030 | 0.0004 | 86.67 | |
| 0.0014 | 0.0002 | 85.71 | |
| M Aero NS | 0.0014 | 0.0003 | 78.57 |
| 0.0024 | 0.0008 | 66.67 | |
| 0.0025 | 0.0006 | 76.00 | |
| M 400 | 0.0010 | 0.0007 | 30.00 |
| 0.0011 | 0.0008 | 27.27 | |
| 0.0014 | 0.0010 | 28.57 |
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
The three supplied products have been tested on six soils. The M Aero was the only product to work on all six contaminants. The M Aero NS worked on all except the ink. With further cleaning time, the ink would have been removed by M Aero NS.
