Soak them with extra hot water and urnex!

our store uses the restroom cleaner, then dump it in the sani water for a bit, and then we run it through the machine. i’ve seen a lot of people say not to use the magic eraser because it causes these small scratches where bacteria can grow, but that’s what i have seen so don’t take my word from it. our tea pitchers aren’t stained unless it’s from the pineapple refresher which is a lost cause because no matter how much we scrub, it won’t come off, so we have been labeling our pitchers for pineapple base use only. i would recommend that, so you don’t have to deal with all the pitchers lookin ugly.
