Trial #5
To evaluate top ten products on fifth supplied ink
The top ten successful products from the previous trial were used at full strength and room temperature. Twenty preweighed coupons were coated with the supplied Sakura Coatings Product Company Solid Marker (yellow). Once dry, a second weight was recorded to determine the amount of ink added to the coupon. As in the last trial, two coupons were used per cleaning alternative. A handheld swab was immersed into the cleaning product and then manual wiped across the coupon for up to one minute. Following the cleaning, the coupons was wiped dry for 5 seconds. Observations were made, final coupon weights recorded, and the average efficiencies were calculated.
Six of the ten products removed nearly all of the yellow ink from the aluminum coupons in under 60 seconds of manual wiping. The table below lists the amount of ink applied, the amount remaining, the efficiency and the time needed to clean the ink.
