Trial Number 5

Trial Purpose:

To evaluate industrial cleaners for the removal of oil from provided carbon steel contaminated parts.

Date Run:


Experiment Procedure:

The cleaners were put into beakers and heated to 140 F in the ultrasonics tank. The coupons were weighed for dirty weights and once the cleaners were at the correct temperatures, the coupons were put into the beakers. The ultrasonics tank was turned on and ran for 15 minutes. The coupons were taken out and left to dry fully. Once dry, the clean weights were taken. The coupons were cleaned again till all remaining oil was removed from the coupons and the initial weights were taken. The ultrasonics tank was run at 40 KHz.

Trial Results:

All cleaners were effective at removing the oil from the surface of the parts and all had over a 99% removal effectiveness. Visually Surface Cleanse out performed the others and did not have many residual spotting left on the surface whereas the Mirachem and Micro 90 had some spotting left on the surface of the part. 

Cleaner Initial wt. of cont. Final wt. of cont. Average
Mirachem 2:1 0.2032 0.0013 99.36
Micro 90 2% 0.1880 0.0006 99.68
Surface Cleanse 2% 0.2326 0.0006 99.74

Success Rating:

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


Additional testing with a rinse step for Mirachem and Micro 90 is needed to try and minimize spotting. Next steps are to clean coupons with Surface Cleanse and send them out to the company to test for adhesion performance.
