Question: can i use isopropyl alcohol to clean my bowl?
Answer: The folks at over WikiHow suggest that cleaning your glass pipe doesn't have to be so hard. Just scrape off the bulk of the resin and then drop it into a Ziploc baggie with 90-100% isopropyl alcohol for a good three-hour soak. You can also use a bit of non-iodized salt as an agitator for a faster cleaning.
