Also if you don't like to use salt you can go to a smoke shop and buy pipe cleaner sticks... and they will scrape the alcohol soaked resin just as good as the salt. The salt is just a lot less work because all you do is shake it after its soaked. The pipe cleaners are basically wire with brissells on them... So you after soaking the piece you have to manually cram the pip cleaner in there and scrape it off the walls, which can also make a pretty messy clean up.
