No worries, happy to answer.

• For the banger, I’ve been using a small Pyrex glass dish, with another dish of the same size to serve as a lid when I’m not soaking. I’m able to soak it about a dozen times before the iso gets too dirty and I replace it. I’ve never had a banger that required a soak after each use, but it’s so worth it because the dabs taste incredible.
• For the bong, I just dump epsom salt + iso into it and make sure they get into all the chambers, then let it soak

EDIT: Rinsing + shaking with super hot water afterwards is a must.
