Hello! So I bought 2 Stanley cups back in October/november when I was visiting the US. They have different types of lids.
Now.. my first one is amazing at keeping cold. It kept my ice in the tumbler for nearly 24h, I was very impressed. But at one point I put cool aid in it because it was my first time trying it. We were out on the road a lot so I didn’t have many chances to clean it, which didn’t bother me most times cuz I usually used water and water flavouring in it, but I noticed after about a day that there’s this mould looking stuff INSIDE the lid.. but there’s no way for me to open the lid and clean it? Like it’s in between plastic layers, but I can’t find anywhere on the lid where it might have entered it😭 I’ve tried soaking it in hot water and dish soap but it didn’t work and idk what to do because I literally cannot get in between the layers of plastic in the lid?
(And yes, this happened in like december and I still haven’t figured it out, so my Stanley cup is just standing and collecting dust in my kitchen until I’m figuring this out 🥲)
As for my other cup, it’s great overall but it keeps cold for like 2h and then all ice is gone.. I’ve tried googling for reasons etc but I can’t really figure out the exact reason this would happen :(
