Hey All, I work in a lab that goes through a lot of 1gal brown glass bottles of 100% isopropanol, I recently brewed a stout to sour and wanted to split it to compare different brett strains, so I took a bunch that were getting tossed. The bottles, however, have an off smell to them, not of isopropanol but I'm not sure what it could be. I've rinsed them with a high pressure bottle washer our lab has, but the smell remains, albeit at a lower intensity.
I don't want to ruin my beer, does anyone have any suggestions on proper cleaning procedure to make sure there's nothing left in there? It's glass, it should have been additive free and the IPA should evaporate cleanly, so I think it would be ok for reuse as much as a glass carboy is. Would an overnight soak in oxyclean be enough? Hot water? Any suggestions would be great. Thanks guys!
