I'd like to help you, but I don't have a Jelly Case. If it is made of the kind of material I think, you'd have to be careful of what you'd use because the chemicals could end up pitting the surface of your jelly case. You could try just using water?
Not sure what buger was saying?
Heres an idea, you could Call/Email Live Clean Solutions or Enzyme Solutions or even WowGreen and see what they have to say?
