As I read this with an engineer's perspective and start parsing it, I come up with more questions:
"cleaning grease" from what? using what process? and what results comparison methods?
Is "oil" equivalent to "grease"?
What were your results?
"degreasing" something is usually a process where you transfer the grease onto/into something else to get it off/out of what you want cleaned.
Typically this involves some kind of physical movement of some cleaning/absorbing material, like
1) Presure washer where you use a high pressure spray of a solvent to erode and splatter the grease/oil somewhere else
2) Wiping with towel/sponge to transfer the grease/oil into the towel/sponge
3) Submersion in water and scrubbing/agitating so that the grease/oil floats and can be skimmed off or decanted
Assuming, liquid hand soap...
Let me guess your results, a glass surface with a very small amount of grease was easily cleaned by all of you liquid cleaners so you didn't see any significant difference. Am I close or not?
