Trial Purpose:
To evaluate vendor recommended cleaner for all three contaminants.
Date Run:
07/11/1999Experiment Procedure:
The client supplied cleaner was made into a 5% solution by volume using DI water in 400 mL Pyrex beakers and heated to 130 F on a hot plate.
Three preweighed coupons were contaminated with the each of the three contaminants and weighed again. Coupons were cleaned using the client supplied cleaner using stir-bar-agitation for five minutes. Coupons were rinsed in 120 F tap water for 30 seconds and dried using a Master Appliance Corp, Hot-air gun model HG-301A for one minute at 500 F. After cooling to room temperature, final weights were recorded and cleaning efficiencies were calculated.
SUBSTRATE MATERIAL: Aluminum Coupons (5052)
CONTAMINANTS: Tuf Draw Vanishing Film 2889 (CAS #: 64741-65-7); Lubricant Mix [Hydroil AW-3 9petroleum hydrocarbon), Express Gear Lubricant F]; Tower Oil & Technology Company LS-H-213 (CAS #: 8052-41-3)
Trial Results:
The Ultra Blue 100 cleaning solution was effective in removing the two drawing compounds, yet it could not clean the lubricant mix very well. Table 2 lists the calculated cleaning efficiencies for the three contaminants.
Table 2. Cleaning Results
| Tuff Draw | Lub Mix | Tower | |
| Coupon 1 | 100.06 | 74.77 | 100.11 |
| Coupon 2 | 100.1 | 73.37 | 100.09 |
| Coupon 3 | 100 | 72.9 | 100.04 |
| Average | 100.05 | 73.68 | 100.08 |
Success Rating:
A follow up test, usually based on company input.Conclusion:
The Ultra Blue 100 cleaning solution was effective.
