To evaluate client requested products on fourth supplied soil.
The three cleaners were diluted to 5% using DI water in 600 ml beakers. All three products were heated to 120 F on a hot plate.
Nine preweighed titanium coupons were coated with client supplied peanut oil, using a hand held swab and then weighed a second time to determine the amount of soil added. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. Coupons were rinsed in tap water for 15 seconds at 120 F, followed by air blow off at room temperature. Once dry, coupons were weighed a final time and efficiencies for each cleaner were calculated.
All three products removed over 90% of the peanut oil. 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||0.1218||0.0155||87.27|
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 products will be used on the fifth supplied soil under the same conditions.
