Trial Report



Trial Number 2

(Client Number 368, Project Number 2)

Trial Purpose: To evaluate effects of cleaners on painted products for stain removal or cleaning purposes.

Date Run: 05/29/14

Experiment Procedure:
Three coupons were placed in a Gardner Straight Line Washability unit. A Kimberly-Clark Wypal reinforced paper towel was attached to the cleaning sled and soaked with 4-6 sprays of cleaning solutions. Each coupon was sprayed 3-5 times with the same cleaning solution. The cleaning unit was run for 20 cycles (~33seconds). At the end of the cleaning; bottom part of the coupons were wiped once with a dry paper towel. Final weights were recorded, efficiencies were calculated and recorded.

Success Rating
Test inconclusive.

Conclusion
None of the cleaning products used proved to be effective in the task of removing wax pencil or wax crayon from a stainless steel surface. This experiment, if repeated, should be done with different cleaning solutions.
