I done fucked up. I know some of my drink cups say handwash only, but I thought that was due to their vacuum chambers.

I assumed (wrongly) that these two bottles would be ok. They are clearly not made from whatever Nalgene is made from.

Meanwhile, I have some cheap vacuum wall plastic tumblers from Walmart, going on 15 years now, that I’ve always tossed in the dishwasher.

Also, I’m getting strong deja vu from my shrinky dink bottles. Have I done this before? Or seen a post on here if the same? I can’t recall.

Edit: hello adhd brain, I forgot to provide details. Red 1L Nalgene for scale. The two bottles beside it used to be the same size before yesterday. ☹️
