Trial Number 0

Trial Purpose:

To find a cleaner that will remove the diesel fuel from the inside of the supplied part

Date Run:

08/14/2007

Experiment Procedure:

Four products were selected from the lab's on-line database, www.cleanersolutions.org, based on client supplied information about soil and surface materials. Each product was heated to 130 F on a hot plate. Solutions were used in a 1000 ml beaker and immersed into a Branson 3510 ultrasonic unit and degassed for at least 5 minutes. Cleaning of the part was conducted in 5-minute intervals. Observations were made after the cleaning time to determine the success of the product. If the product was unsuccessful, the next cleaning solution was used.

Trial Results:

Two of the products were successful in removing most of the diesel exhaust "char" from the inner portion of the supplied part. 

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

Additional cleaning was not conducted so that the part would not become damaged.  Part needs to be inspected by client to determine if it is as clean as it needs to be.
