Yes, irregardless of how clean they may look, they get an alcohol treatment.
it’s when the vendor DOES NOT disclose that they haven’t bothered to even run a pipe cleaner through that upsets me - especially if the item was expensive.
Can't argue with that at all. Me, I usually buy only from people with stellar (99.9% or higher) &/or that I know from experience will only provide quality cleaning. Occasionally, though, I'll take a chance if it's a pipe I really want. Once or twice I've had not as good luck on those, but most times it's been done right. Still, though, I'd be bent too if I laid out Big Bucks & got one that hadn't been at least partially cleaned.
