Well, Liz N Dan, I know when I goo kit and have sticking wax, it is caused by 2 things. One, the wax overheats and gets really soft causing it to stick (this comes from the guy at Magma Tower) and 2, he says a lack of surfactant which would be your dishsoap. Sometimes with the dish liquid there is too many other chemicals in it that react with the wax. Some have tried Bubble soap. Called Magic Bubbles I do believe. This is a little more pure then dish liquid. I never had luck with any of this stuff but again I haven't made my own lava. I always just use the bought stuff from gookits.com. If you lava is reacting with your dish soap then it's some sort of a chemical reaction with whatever you made your lava out of. You can order surfactant from magma tower and try that. There are more professionals on here then I that maybe can give you come other ideas.
