Trial Purpose:
To evaluate successful cleaners under varying operating conditions
Date Run:
02/25/2002Experiment Procedure:
Two products from the previous trial were made into two concentrations, 5 and 10%, using DI water in 600 ml beakers. These dilutions were heated to two temperatures, 130 and 150 F on a hot plate. The various operating conditions used were:
| Product | Conc (%) | Time (min) | Temp (F) |
| Surface Cleanse 930 | 10 | 10 | 130 |
| Surface Cleanse 930 | 10 | 10 | 150 |
| Surface Cleanse 930 | 10 | 5 | 150 |
| SC Aircraft & Metal | 5 | 10 | 130 |
| SC Aircraft & Metal | 5 | 5 | 150 |
| SC Aircraft & Metal | 5 | 10 | 150 |
| SC Aircraft & Metal | 10 | 5 | 130 |
| SC Aircraft & Metal | 10 | 10 | 130 |
| SC Aircraft & Metal | 10 | 5 | 150 |
| SC Aircraft & Metal | 10 | 10 | 150 |
Thirty preweighed coupons were coated with the New England Industrial Lubricants NEILCUT 333 using a hand held swab. Coupons were then weighed again to determine the amount of lubricant added. Three coupons were cleaned in each solution for either 5 or 10 minutes using stir-bar agitation. Following cleaning, the coupons were rinsed in tap water at 120 F for 30 seconds and dried using a Master appliance heat gun at 500 F for 1 minute.
Once coupons were cooled to room temperature, final weights were recorded and efficiencies were calculated.
Trial Results:
The SC Aircraft & Metal cleaner was successful in removing the oil under multiple operating conditions. The effectiveness of the Surface Cleanse 930 decreased as temperature and time were increased. The following table lists the efficiencies for both products under the different settings.
| Cleaner | Time/Temp | Coupon 1 | Coupon 2 | Coupon 3 | Average | Std Dev |
| Surface Cleanse 930 @10% | 10/130 | 76.10 | 73.84 | 87.23 | 79.06 | 7.17 |
| 10/150 | -26.61 | -108.36 | 17.33 | -39.21 | 63.78 | |
| 5/150 | -49.27 | 3.48 | 6.74 | -13.02 | 31.44 | |
| SC Aircraft @ 5% | 10/130 | 100.44 | 102.09 | 100.41 | 100.98 | 0.96 |
| 5/150 | 98.93 | 98.72 | 99.36 | 99.01 | 0.33 | |
| 10/150 | 97.84 | 93.42 | 85.89 | 92.38 | 6.04 | |

| 10/130 | 100.46 | 100.80 | 100.98 | 100.75 | 0.26 | |
| 5/150 | 100.18 | 100.07 | 98.92 | 99.72 | 0.70 | |
| 10/150 | 100.58 | 100.19 | 97.68 | 99.48 | 1.57 |
Success Rating:
A follow up test, usually based on company input.Conclusion:
The increase in temperature, time, concentration or the combination of each resulted in improved cleaning efficiency for the SC Aircraft & Metal cleaner.
