Home remedy suggestion for a stinky thermos

I recently bought a double-walled stainless steel thermos for drinking water to carry on my bicycle. All of the solutions that came up on a Google search were for removing odors on used ones that had contained coffee, soup, etc. My thermos is brand new; it's a factory sourced odor. The odor appears to be chemical. I did try a couple of suggested solutions: baking soda & hot water; baking soda & vinegar, which recommended screwing on the cap. Try putting on the cap while a volcanic eruption is happeningšŸ˜±. Neither method made much of a dent in the problem. As I expected, the thermos was made in China. Interestingly, the screw on cap (contains some plastic materials) is odorless.
Any suggestions will be appreciated.

I use diluted bleach to clean stored flasks which I rinse out thoroughly after a soak and shake. This may help with manufacturer's odour, I suppose it couldn't hurt to try.

Click and Clack used to recommend heated coffee beans as a deodorizer for cars, it might be worth try in try his case.

Take it back and buy something else. Preferably Made in USA.

I did buy one made in the USA. It was plastic and double insulated, but filled with ice, it it turned to warm water in about 1 1/2 hrs.

I was given one of the "camera lens cups" with a stainless steel liner, which I thought was very cool. Unfortunately it left a metal taste in my mouth when drinking coffee, water, tea. I quit using it!

Surprisingly, there was no "after taste" when I used it with water (used it only once so far). It appears I am making progress using baking soda and hot water and letting it stand for a while.

Sometimes worth paying the price for a name brand unit. Have never had a problem with Thermos brand. The 10% bleach solution will remove proteins and kill viruses and bacteria. But they probably have coated the inside with an oil, so very hot soapy water might be the best bet.

I agree, but I did not locate a Thermos brand that is sized to fit a bicycle bottle carrier. The plastic made in US bottle was odor free and tasteless but the insulation was significantly inferior.

Hot soapy water. What you are trying to remove is the oil that is used in the forming process of the bottle.

Try carburetor cleaner to remove oil/grease. Rinse with hot soapy water.
Flush with clean water.
