To evaluate client supplied cleaning solution on all listed contaminants and substrates.
Date Run:
09/30/1999
Experiment Procedure:
The cleaning solution was diluted to 5% using DI water in a 600 mL beaker. The solution was used at room temperature. Coupons were cleaned for five minutes. Rinsing was performed for two minutes using tap water at 120 F and air dried for about two hours also at room temperature. After drying was complete, final weights were recorded and efficiencies were calculated.
SUBSTRATE MATERIAL: 1-Nickel/Copper (202-715); 2-Stainless Steel (202-410 B-85); 3-Aluminum (202-2024 T-3); 4-Ceramic; 5-Steel (202-1010 B-79)
CONTAMINANTS: Table 1 lists the contaminants and the related CAS#s for this trial. Table 1. Contaminants Cleaned
BioSolve was successful in removing the oil, lubricant, and grease from the coupons’ surfaces. The
cleaner was not very successful in removing ink. Most of the adhesive was cleaned from the surface. Some foaming
was observed during the make up procedure of the solutions. Table 2 lists the percent removal for each contaminant.

Success Rating:
A follow up test, usually based on company input.
Conclusion:
The cleaner evaluated had success in removing the contaminants recommended by the manufacturer. Higher temperatures and more agitation could improve the results overall and especially for removing the adhesive. The dried ink has been consistently hard to remove in other trials. A different ink may be easier to remove.
