To add on to the OP, if you're cleaning any kind of bong or bigger bubbler, these are great. You fill the piece up with a good amount of salt and 91%+ isopropyl alcohol, use the caps to seal it and shake the shit out of it. Prior to ordering a few packs of those, I had always just taken some saran wrap, layered it a few times over the openings and rubber banded it in place to avoid any leaks when shaking.

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.

I have a very similar setup, I use 99% rubbing alcohol and Epsom salt as well. I'm a clean freak with my glassware so I do it every day, but it only takes a couple minutes. I boil some water, run that through all the percolators, then pour in a bit of alcohol with Epsom salt and do the same before hitting it with hot water one last time. Just slap some silicone bong caps on both sides and give it a few healthy shakes, the tar and shit comes right out.
