I have found with my ultrasonic cleaner that greasy stuff does better with pre-clean. If the solution is clean and the parts are not greasy works really well (think old carb that's not greasy) with gas stains). If parts are greasy it seams to not work as well basically turning the grease and water into a homogenized solution (like 2% milk) where the grease is now evenly dissolved in the solution and still all over the part. I also found that more detergent was a good thing. I now save up parts to clean and go from least oily to most.
