Best manufacturer in Minnetonka, Minnesota (MN) 2024

I received Popco as my 75 year old birthday gift from my grandchildren. When I used it for the first time it said to fill up to the measuring lines. I mistakenly thought the fold lines were the measuring lines. So the popcorn did not pot. I continued to increase the time. In the mean time I was distracted and the popcorn burned. I would like to know how to get rid of the smell. I tried vinegar but it still has a very strong odor. Is there any way to get rid of the smell? ~Sumako
