I tend to stay with EncapGreen, as it is a vegetable-based product, and that is my primary marketing message. On some large commercial jobs, where price is the primary consideration, and I am using my 24" Cimex, I will use Releasit's DS, as it creates the foam trail that helps to keep the Cimex's cleaning paths from overlapping too much.
As far as commercial cleaning products go, the Releasit products are pretty benign, health-wise. I think the strongest part of their recipe is isopropyl (rubbing) alcohol.
