It comes down to the fundamental structure of the technology. The nature of an emulsion cleaner is trying to clean the soil, absorb it, solubilize it, and carry it away from the part to keep it clean. The nature of the technology is that it takes the soil into the nature of the cleaner itself. It is not just undercutting it or reacting with it. That’s why they tend not to separate. There are some techniques and products that lend themselves whether its with heat or ultrafiltration to strip out some of those oils but it’s not nearly as simplified as the whole idea of letting it sit in a quiet tank and let gravity be your separation mechanism. That is why you don’t really have skimmers on emulsion cleaner tanks.
