Wow, worked great!!! My thermos is super clean!!!

Thank you! Best solution to this problem by far.

Your method worked very well for me, my 2 travel mugs and my big thermos came out perfectly clean. Only thing I did different was that I used a bottle brush to scrub outt the 3 vessels before rinsing them out. Thanks, Matt!!!!:):):)

Love your Pyrex tea pot! Thanks for the video.

Tried this on two old very dark brown Stanley Vac bottles. Came out like new. Never would’ve expected oxyclean to do as well as it did. This needs to be on the instructions of all thermos type bottles.

I always put a dishwasher tablet inside the thermos and poor hot water in it. Leave it rest for 1 night and the next day I rinse the thermo with hot water and all the build up coffee stains will come out of the thermo.

Genius

What about the stains on the silicone seal!?
