To evaluate supplied products for all purpose cleaning using manual cleaning
Soil Preparation: A mixture of three cooking oils/greases was made. A melt blend of 33% vegetable shortening, 33% lard, 33% vegetable oil and 1% carbon lampblack was made up fresh for the testing.
Preweighed ceramic, painted steel and plastic coupons were coated with DCC17 soil using a hand held swab and were allowed to dry for 24 hours at room temperature. The contaminated coupons were weighed again to determine the amount of soil added.
Three coupons were placed into a Gardner Straight Line Washability unit. A Wypall X60 reinforced wipe was attached to the cleaning sled and soaked with 1 spray of water with a VWR bottle. Each coupon was applied with 0.5 gram of powder solution accompanied by a spray of water (~1 mL). The solution was allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 20 cycles (~30 seconds). An additional wipe cycle was done with one spray of water on each coupon and new Wypall for rinsing purposes. Coupons were let to dry 24 hours before reweighting and efficiency was calculated.

Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
All products were effective in removing DCC-17 soil from tested surfaces. Comet had the highest removal efficiency of 89.82% followed closely by Ajax at removal of 89.38%. BrandBuzz had the lowest cleaning efficiency but came very close to the other products at 86.28.
