If you’re REALLY invested in cleaning pitchers, the best way to do so I’ve found is urnex soaking (15-20 minutes) with thorough scrub (blue scrub pad). Run it in the sanitizer afterward.

I think its just new lol but theres a plastic wrench (i think its pictured here, behind the dirty one) that you can use to remove the blades and really scrub it. I cant find the one at my store lol we're all disorganized but its supposed to be in the toolbox
