Sure, you can just scrape out your pipe and keep going, but sometimes the resin builds to the point where you have to do some deeper cleaning. Instead of scraping and prodding, try soaking it in isopropyl alcohol and salt.
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. If you add salt, you may not need to let it soak for long at all. Just shake the bag until the pipe is nice and clean.
