I agree with the baking soda and boiling water, carefully, but I usually fill it half full, and agitate for several minutes. I once had a really nasty thermos that I took to Lowe’s and had a friend who worked in the paint department strap it to a paint shaker. About three minutes and it was sparkling clean after a hot water rinse. But if you don’t have a paint shaker, spending a few minutes shaking it yourself is good exercise, especially if you switch hands periodically, and makes the job fairly quick and easy. I normally follow up with a shake/agitate with hot water and a good dish detergent like Dawn™. Io it still has an off smell, use half cup of white vinegar with two cups of hot water, and agitate vigorously for about a minutes and rinse in warm water.
1.) Fill one or two tablespoons of dishwasher powder in your thermos
2.) Fill up your thermos to the brim with hot water and stir lightly
3.) Wait for two or three hours
4.) Rinse the thermos three or four times with clear water
5.) Enjoy a thermos, that is perfectly clean, and looks and smells like brand new inside
I opened a thermos that had been left with a residue of milk & tea for a year. It stank and had a tough film of milk/tea. Here’s what works:
Put some baking soda in the thermos (about 1/4 cup) and set it in the sink. Pour in a little bit of boiling water. When it stops foaming, pour in a bit more. Repeat until the thermos is full, and dump it out. You’ll probably see bits of brown film at this point.
Repeat: Baking soda, followed by boiling water a bit at a time until it’s full. More and more brown film will float up with the foam.
You might need a third go, or even a fourth. You might just need two. But when you empty the thermos and it’s shiny clean inside, you’re done. I wash it at that point with soapy water, just on GP.

Chuck a dishwasher tablet in it, fill with hot water (slowly, it can foam and spill over) and leave it for a couple of hours.
Much more effective than sodium carbonate (washing soda) Na₂CO₃, or baking soda NaHCO₃. They work but can take an inordinate amount of time.
