I invert it, knock it as hard as I can in the trash, then spray it with my sink or shower sprayer. That gets 95% off. I then soak it in the PBW I am using to clean the kettle and swish it around a bit with my glove on. Im usually at about 98 percent at that point. I let it dry and flip it inside our and rightside in a few times and I get to 99 percent. Theres always a tiny tiny bit of hop residue left at which point I figure it probably wont make a difference in the next boil anyhow.
