Trial Purpose:
To evaluate cleaners for replacing TCE in removing oil from metal.
Date Run:
02/20/2002Experiment Procedure:
Eight cleaners were selected from the lab's databases of testing and vendor information. Products were selected based on client supplied data. Each solution was diluted to 5% using DI water in a 600 ml beaker and heated to 130 F on a hot plate. Twenty-four preweighed coupons were contaminated with the New England Industrial Lubricants' NEILCUT 333 using a hand held swab. Coupons were weighed again to determine the amount of oil added. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. A 30 second rinse in tap water at 120 F followed cleaning. Coupons were dried using a Master Appliance heat gun at 500 F for 1 minute.
Once coupons cooled to room temperature, final weights were recorded. Product efficiencies were calculated and recorded.
Trial Results:
Only two products, Warren Chemical Sea Wash 8 and International Products Surface Cleanse 930, removed over 80% of the oil from the stainless steel coupons. The following table lists the amount of contaminant added to each coupon as well as the effectiveness of each. (Three coupons per cleaner.)
| Cleaners | Coupon 1 | Coupon 2 | Coupon 3 | Average |
| Brulin | 82.90 | 64.69 | 78.63 | 75.41 |
| Buckeye | 27.31 | 37.56 | 40.43 | 35.10 |
| Heatbath | 66.97 | 54.02 | 62.23 | 61.07 |
| Safe CleanUp | 86.71 | 64.80 | 51.15 | 67.56 |
| Solvent Kleene | 49.04 | 49.41 | 70.85 | 56.43 |
| International Prod | 78.70 | 76.83 | 87.98 | 81.17 |
| Warren | 80.22 | 93.02 | 88.82 | 87.35 |
| Chem Free | 57.69 | 21.74 | 25.43 | 34.95 |
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
The two effective products will be reevaluated in the next trial at higher concentrations. An additional five new products will evaluated at 5% concentrations as well.
