The first supplied product was used at a 1:48 dilution. The second supplied product was used at three dilutions, 1:64, 1:128 and 1:256. A conventional product was used at a 1:64 dilution. A sixth product that uses electrolyzed water was included in the testing.
Preweighed hard plastic coupons were coated with peanut oil taken from a jar of all-natural peanut butter. The oil was skimmed off the top of the container and applied to the coupons using a swab. Coupons were weighed a second time to determine the amount of oil that was applied.
Coupons were placed in a Gardner Straightline washability unit. A Wypall X60 reinforced wipe was attached to the cleaning sled and soaked with 5-7 sprays of cleaning solutions. Each coupon was sprayed 7-10 times with the same cleaning solution. The solution was allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 20 cycles (~33 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded, and efficiencies were calculated and recorded.
Following the first round of cleaning, a second round of manual cleaning was conducted on the same set of coupons using the washability unit. A second set of final clean weights were recorded, and efficiencies calculated.
All six products removed over 95% of the peanut oil in the first cleaning attempt. Following the second round of wipe cleaning, all removed over 98%. The four supplied products removed over 99% of the oil. The table lists the amount of peanut oil added, remaining after cleaning and the efficiency for each coupon cleaned for both cleaning cycles.
