To evaluate client requested products on the sixth supplied soil.
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.
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 NS||0.0014||0.0003||78.57|
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
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.
