Just a little issue with my Instant Pot pressure cooker

Tweet

Before Christmas, I read on myLot how several myLotters liked their Instant Pot so I got one for Christmas. I cooked black eyed peas that were the best I've ever cooked. My husband agreed. Next I cooked a beef roast with potatoes and carrots, again it was suburb. Recently I cooked a bear roast with the same veggies. It was delicious, but you know the silicone ring in the lid? I can't get the smell of the meat out of it. I tried all the suggestions from Instant Pot.com like baking soda, coffee, vinegar, dishwasher, not much helped. It's almost gone now, but I hesitate to cook something like that again. Have any of you had that problem? It must not be unusual because it's addressed in the help section of the web site. I sure don't want to buy a new seal every time I use it, but sure do like it otherwise.
