Trial Number 2

Trial Purpose:

To evaluate the effectiveness of Crystal Simple Green and SC Aircraft for the removal of oil from stainless steel coupons.

Date Run:


Experiment Procedure:

The cleaners were put into beakers and heated to 110 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:

The cleaners removed some oil but not all from the coupons and there were man dark spots left on the surface of the coupons. Crystal Simple Green removed about 77% of the oil from the coupon and SC Aircraft removed about 75% of the oil. 

Cleaner Initial wt. of cont. Final wt. of cont. Average
Simple Green 1:20 0.2756 0.0647 76.52
SC Aircraft 1:3 0.2975 0.0744 74.99

Success Rating:

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


Neither cleaner fully removed the oil from the substrates. Next steps are to increase the concentration and the temperature.
