Trial Number 445

Trial Purpose:

removing preinco #47 lube of the surface of aluminum using non-toxic cleaners.

Date Run:

05/21/2008

Experiment Procedure:

Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning. 

Products were based on the compatibility of substrate and removal of foreign substance. Used 5% concentration and heated the samples at 135F. The coupons were immersed in a product for 5 minutes, rinsed for 30 seconds in tap water at 120F and dried in 30 seconds.

Success Rating:

Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.

Conclusion:

All products tested surpassed the approval removal rate of 85%.
