I just recently bought the yocan evolve 2.0 and after trying some concentrates in it the bottom leaked oils all over the batter and card ridges and now the entire vaper has become useless please help me fix this issue

Answer:
The Yocan Evolve 2.0 is a next-generation pod-based dab pen that improves the current standard for the pod-based platform.

Please do NOT overload the concentrate material in your chamber.
The bottom of the vape cartridge was leaked, please check did it creaked or not?
If so, please switch a brand new Yocan vape cartridge.

As for how to clean, please try to use a q-tip to clean the vape cartridge chamber.
