I realize your post (and my comment!) will likely draw some fire, however I remember reading that Zmax was actually either Castor Oil or some other commonly available oil heavily remarketed/repackaged. Have no idea if that's the case. I see so called 'photo evidence' and 'case studies' on their commercials and televised endoresments that look real, and real promising. Makes me wonder if it could help. Am interested in this response, as everything I own is old, most likely has carbon buildup, and could benefit if claims are true. Please resist using line about 'swamp land in Florida'.
