Trial Number 0

Four cleaners were selected from the lab's on-line database, www.cleanersolutions.org, based on past testing results matching client supplied information. All products were used at full strength as well as the clients current cleaner. Each solution used at room temperature and cleaning was done with a wiping process.

Three coupons for each cleaner 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). At the end of the cleaning, coupons were wiped also following the procedure the company uses in their manufacturing process. (They were not wire brushed though like in the manufacturing process.) Final weights for the cutting fluid and visual observations were taken for the sharpie coupons. Observations and efficiencies were recorded.

All five cleaners resulted in more than 90% removal of the contaminant. The table below shows the amounts of soil added and removed by each cleaning solution.
