How to clean Thermos?
I recently bought a Zojirushi SJ-JS10-XA thermos flask. Overall, it’s decent, but over a month of use it has accumulated amoeba & drink residue everywhere. How do I clean this?
I usually leave it in warm, soapy water, rinse it strongly, etc., however the lid of this flask is very complex with many nooks for grime to accumulate. I can’t find anything online about how to take it apart to wash the individual components etc. What the hell should I do?
As an example, the lid has a small pouring opening at the top. This is roughly 1cm in diameter & bends halfway through. The inner opening is tiny. The entire thing is filled with grime & I can’t fit any instrument in to clean it, nor would any small enough instrument be able to move around the bend. What am I supposed to do about this?
Many thanks for any ideas
