I use my crafty fairly heavily (5-8 bowls on weeknights, 10-15 on weekends). I'm pretty bad about cleaning it, and only get around to doing so once a month. It's gets pretty gummy in the screen, and I'm always amazed at how much better it tastes after I clean it. I don't usually have to scrape because I put my CU in a small jar with a lid, fill it so the cu is fully submersed in ISO, and then put it into a hot water bath in my plugged up kitchen sink. After about 5 mins, I shake it like crazy and my cu looks brand new.How often do you guys clean your CU? I'm a fairly light user (one charge usually last me a day and a half or two) but it has started to get a little of that 'burnt popcorn' taste so I'm probably going to clean it tonight even though when I looked inside it wasn't terribly gooped up.
I'll probably pick up a 2nd CU so I can keep them in rotation like I do the glass stems in the ascent. I'm thinking a 10min soak in ISO with some agitation should be sufficient. However I don't like to use alcohol on plastic parts more than necessary. Oh, & do you scrape before you soak, or just soak? I'll be tossing the ISO in the mason jar of reclaim in the freezer so it won't be going to waste.
However, you can totally smoke the vapor resin, so if you want to do that, I would recommend scraping before you soak it in alcohol.
