Can someone tell me what's the difference between the green stuff and the
orange?  My Westy came with the green stuff which I assumed was the wrong
stuff (with phosphates) but now I read that the green stuff is
phosphate-free.  Is the color the only factor here or is it brand?  I was
going to put in some of the Texaco phosphate-free stuff (not sure of color)
but would this have similar problems as the orange?
