- andrewflnr 2y agoLooks like you can use HDPE, actually. I think that's what it's usually shipped in, too. https://www.sciencemadness.org/whisper/viewthread.php?tid=157030 https://www.sciencemadness.org/whisper/viewthread.php?tid=15...
- marcosdumay 2y agoWell, HDPE would be way easier to manufacture there. But people on your link are mostly unanimous: "Quite often the caps are the weakest point. And as mentioned above HDPE bottles tend to sweat over time. I would vote against long time storage (years on end) of sulfuric acid in HDPE bottles."
- andrewflnr 2y agoThey are not nearly unanimous. > I have also a HDPE bottle of 98% sulfuric acid over a decade old without single hint of issue. And they're talking about almost pure acid, which is not nearly what's going on in at atmosphere that's mostly CO2. Venus is probably not even as strong as drain cleaner.
