Trial Number 2

Trial Purpose:

To evaluate supplied cleaner for oil-grease cleaning using manual wiping.

Date Run:


Experiment Procedure:

The supplied cleaning product was used at the recommended concentration (2%).

Three preweighed aluminum and ceramic coupons were coated with an oil-grease mix collected from a dirty engine using a hand held 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 Wypall X60 reinforced wipe 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 solution was allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 20 cycles (~30 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded and efficiencies recorded.

Trial Results:

The #120 Peroxide Multisurface Cleaner was effective in removing the oil-grease mix from the two surface types. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
