There is no way. We just designated 2 pitchers to specifically pineapple and don’t put it in any others

Yeah, first you gotta try scrubbing for ten minutes only to see nothing shy of god himself will get those stains out. Second, you accept defeat.

If you want to bend some rules, apparently urnex works alright,

It’s technically not allowed but on tough stains we used to pour urnex in hot water and let the dishes sit in it and the stains would come right off. Have not tried it on this but if you do that, make sure you wash again.

magic erasers. They work like a CHARM.

No it’s like the kiwi just have a designated pitcher for it

They will be stained forever 💀

I’ve seen some people suggest white vinegar.
