How to keep clear balloons clear

I am having a hard time making my helium filled clear balloons crystal clear. I bought the super hi-float (the woman at hi-float said I can use super hi-float) and did the dip balloon with pencil method. Although it made it a little better, it was still cloudy. I then put some hi float in the balloon first, then dipped.. It did make it clearer that way. I tied with a clip and waited until the next day.. The balloon deflated a little and the balloon was cloudy again.. I fiiled back with helium, and balloon still looks streaky and somewhat cloudy. Am I doing something wrong??? help!!!
