Yeah, if you need to deep clean acrylic good ole soap and water do a pretty good job. Otherwise best to keep chemicals away from it.Ok, well I’m assuming because of these micro fractures, it’s a good enough reason to avoid dipping the pipe cleaner in anything to run through them, and only use dry pipe cleaners through the stems.
I can also say, as long as I’ve been running a dry pipe cleaner occasionally through the stem while smoking, which everyone should be doing, and then after smoking, I’ve not noticed cleaners dipped in anything after smoking, making a better difference, so now I avoid it.
