So I've been pipe smoking for a few weeks now and I last week bought a savinelli pipe which i love. As it's new ive been going by the rules of only smoking it every 24-48 hours. I've also been cleaning it with a pipe cleaner after each smoke. What ive noticed is that despite pushing a pipe cleaner through till it runs clean I'm still getting a bitter taste after about half a bowl. its like the condensation tastes foul and i can see a yellowish liquid gathering at the very tip of the bit. Is this because I haven't done an alcohol clean yet? Hope that's not a too stupid question!
