There’s a couple of ways to do it but one of them is to bake it in the oven at 160 for 30-60 minutes. Then hand wash with unscented washing up liquid in future.
Yeh, I donated ours. Happens when I hand washed it too. Also happened with my first so now just sticking to ceramic and metal baby cutlery which is working better
We are using Ecover Zero tablets too etc…
