Orange TKO is a d-limonene product that has had the oils taken from it. If I am correct, Greensense orange still has the natural oil and hence the streaking problem.
Thr GreenSense product is labeled as "100% d-limonene," but labels can mislead sometimes--so Kathe still could be right about the ~5% other organic compounds.The versions of that product that I've seen didn't have either the aroma or the appearance of a full spectrum citrus oil extract, but it could contain some of the fractions besides d-limonene. The difference in behavior likely is that the GS product does not contain emulsifiers (at least it didn't the last time I looked), and the unemulsified d-limonene fraction essentially is insoluble in water. When added to water in an unemulsified state, it forms a separate organic layer on the water surface. That insolubility separation state makes it difficult to apply an even d-limonene/water mixture and it makes it difficult to remove any d-limonene that is applied to a surface (the unemulsified mixture doesn't have much self-rinsing character). In contrast, TKO contains a significant amount of emulsifier(s), which one would guess is/are of a synthetic nature. GS is hard to beat for pure d-limonene power/content (the way most of us would use it usually requires adding something to emulsify it--coconut oil, soap, detergent, etc.), and TKO is a fine cleaner.
