Trial #5
To evaluate the efficacy of previously identified solvents and mixture in removing sharpie ink from aluminum panels via manual wipe
Three aluminum coupons were used per cleaner for a total of 9 coupons. The coupons soiled with sharpie ink by drawing a squiggle along the bottom third of the coupon. The dirty visual rankings were then recorded. The coupons were then cleaned with their respective cleaners by manually wiping a paper towel wet with the cleaner on the coupons for a total of 5 seconds. The cleaned visual rankings were then recorded.
Visual Rankings Key:
1: 100% soil removed
2: 75% soil removed
3: 50% soil removed
4: 25% soil removed
5: 0% soil removed
