Trial Purpose:
To evaluate supplied cleaner for oil-grease cleaning using manual wiping.
Date Run:
01/30/2007Experiment 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 handheld 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.
| Cleaner | Initial wt | Final wt | % Removed |
| Aluminum | 0.0387 | 0.0069 | 82.17 |
| 0.0239 | 0.0045 | 81.17 | |
| 0.0289 | 0.0044 | 84.78 | |
| Ceramic | 0.0206 | 0.0008 | 96.12 |
| 0.0135 | 0.0013 | 90.37 | |
| 0.0109 | 0.0017 | 84.40 |
Success Rating:
A follow up test, usually based on company input.Conclusion:
The #120 Peroxide cleaner removed over 85% of the oil-grease mix using manual wiping for cleaning.
