I'm hoping someone who trucks their tea or coffee about in a thermos can help me.
I've had a Nissan Thermos for years and it's become impossible to get the stains out of the seal. Other than that, it still keeps my coffee drinkable in the morning.
Is it even possible to get a replacement for the seal any more? I could have sworn I've seen such things, but I've searched the Internet and even the real world with no luck.
