The provided product tablet (~2.5grams) was dissolved in 16 ounces of water. A comparative product was used at the ready-to-use concentration.
Preweighed ceramic, plastic and painted steel coupons were coated with a mixture of shortening (33%), lard (33%) and cooking oil (33%) using a handheld swab and 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 Kimberly-Clark Wypal reinforced paper towel was attached to the cleaning sled and soaked with 2-3 sprays of cleaning solutions. Each coupon was sprayed 1-2 times with the same cleaning solution. The cleaning unit was run for 20 cycles (~33 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded, efficiencies were calculated and recorded.
Both products removed more than 95% of the soil using manual wiping for 30 seconds. The table lists the amount of soil added, the amount remaining, and the efficiency of each coupon cleaned.
