I never put it in the dishwasher. I use denture cleaning tablets as they work the best. I've tried everything from ice, salt, lemon juice, peroxide baking soda in all forms of combinations. You name it, everything but soap. Denture tablets work the best so far. Fill it full of hot water and drop in two tablets. Let it soak overnight and brush out in the morning. Sparkling. I also throw my seals in there too. And I cap it with the stopper so it cleans the bottom of it. Don't seal it because it'll probably blow up.

I'm a truck driver and heavy equipment operator. This thing has taken some abuse but it's still going strong!

Denture tablets are the way.

Thermos funk tends to be from volatile oils and a layer of casein from dairy. The dairy layers up, provides a home for oils which get rancid and gross. Denture tabs were literally designed to combat biofilms exactly like these.

I do one tablet in the mug and one in a cup with the lid gaskets, soak a few hours and a quick hit with a bottle brush. Keeps the mouthpiece sparkling, hasn't damaged any of the gaskets.

Are denture tablets better than those citric cleaners you can dunk these in? I've seen them used for cleaning build up on rice cookers.

Denture tablets are specifically made to break up biofilms. I don't know if they're better as I've not used citric acid for that purpose, but I'd imagine so.

Urnex Clearly Coffee is even better than denture tablets
