Trial Number 2

One gram of Tartar was added into 20 fl oz of water (PH 6.5) in supplied spray bottle of Trio then was electronically charged for 3min. after activating, the PH of activated water was changed into 11. The other cleaner was used at full concentration for test. Four sets of twelve ceramic, stainless steel, and polycarbonate coupons were weighed and then coated with vegetable oil (soybean oil) 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 5-7 sprays of cleaning solutions. Each coupon was sprayed 7-10 times with the same cleaning solution. The cleaning unit was run for 20 cycles (~33 seconds). Final weights were recorded, efficiencies were calculated and recorded.

Chemistries Evaluated: Trio (1g of Tartar, PH 11), Water (PH 6.5), Clorox Green work All-purpose Cleaner, Clorox 409 All-purpose Cleaner

Trio and Clorox green work all purpose was effective at removing more than 85% of the vegetable oil from three type of surface. However, water and Clorox 409 was effective at removing more than 85% of the vegetable oil from two of the surfaces (stainless steel and polycarbonate) using manual wiping. However, visually, over than 85% of the vegetable oil on ceramic coupon was removed by Clorox 409 all-purpose cleaner; we suspected that reaming cleaner’s foam affect the gravimetric analysis. The table lists the amount of soil added, the amount remaining after cleaning and the calculated efficiency for each of the ceramic, painted steel and polycarbonate coupons cleaned.

Summary

Trio Product was found to be effective for removing the vegetable oil from various surfaces using manual wiping. It compared well to the other cleaning products supplied for testing.
