Came home from work with some alcohol to clean my pipes and a fresh sack to smoke. had the pipes soaking for a while as I grind the bud and make my musical selection. take one pipe out and start scrubbing the inside with a pipe cleaner and i noticed a rough spot - so i took my resin scraping tool and went to work at it. i scraped a lil too hard and now my mini pipe has a 2nd carb the size of my thumb on the other side. at least his brethren survived the cleaning and smoke well. i toked a few extra tokes in memorandum, feel free to do the same.
