I believe you made the right move with your purchase. If your ACV is cloudy then it probably has the "mother" in it and that is the "good stuff." As far as taking ACV internally, I take 2Tablespoons three time a day when I am taking it. When my body tells me to quit taking it, I back off. I can honestly say I have not had a sick day since finding ACV. If I get the slightest bit of Mucous, I start amping up the ACV and then I add cayenne if any Mucous persists. I believe the ACV makes my liver filter the Mucous better and adds healthy flora to my tummy. I know that doesn't really apply to your Master Cleanse so I hope someone else drops in and gives you some valid info.
