Success Rating:

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

Conclusion:

Quite a bit of the Ester was still on the coupons when I weighed them this morning, so this threw off the results a bit especially on the baked-on oil mixture.  All in all, though, the results looked pretty good.
