I can get my peices pritty clean with just some work.

I usually get a paper clip and bend it into shape. Then get the tap water as hot as it can go. Let and soak for a bit then start scraping. I also use q-tips or pipe cleaner.

I've collected resin from my pipe to smoke a couple times. But i've realized its disgusting because I take it everywhere and fibers and shit get into it and its gross.
