Trial #2
To evaluate two all-purpose cleaners supplied products for Hucker’s soil removal from various surfaces.
Two cleaners (NatSurFact A and NarSurFact B) were received “Ready to Use” (RTU). Nine pre-weighed coupons per cleaner (three Ceramic, three Plastic and three Painted Steel) were coated with a half of a gram of Hucker’s Soil, at room temperature, using a hand held swab. The contaminated coupons were air dried for 2 hours at room temperature and weighed again to determine the amount of soil added.
The three coupons of each substrate were placed in the SLW equipment and a KC Wypal reinforced paper towel was attached to the cleaning sled and treated with two sprays of cleaning solution. Each coupon was sprayed twice with the same cleaning solution. The cleaning unit was run for 20 cycles (equivalent of 30 seconds of cleaning). At the end of the cleaning cycle, the coupons were allowed to dry. Once dry, coupons final weights were recorded and efficiency was calculated for each coupon cleaned
NatSurFact A and NatSurFact B showed efficient removal visually and gravimetrically of the Hucker’s soil on plastic and painted steel, but not ceramic. After the substrates were cleaned in the manual wipe equipment, many contained streaks due to the brush from the manual abrasion equipment.
