What's the best way to clean a Thermos? I rinse it a couple of times with hot water, then add some soap and hot water, slosh it around a bit, rinse a few times, then add hot water and soap and let it sit. It's one of the older metal green ones (the only kind worth a darn IMO), and I love it, but I always feel like I'm drinking stuff that's years old, even though the coffee tastes fine.

I put mine with the opening down in the dishwasher. And I put the cup and cork on the top shelf of the dishwasher too. Works great!

A large bottle brush chucked into a drill! Bacteria and residue laugh at warm water and dish soap.

crushed ice and table salt........ agitate the heck out of it and repeat.......... then you can add a bit of bleach with ice and do it again........ I have cleaned my univac stainless steel one that way for years.

I use a bottle brush covered with baking soda. 2 years worth of truck-stop coffee crud, came right out.

Hot water and baking soda, cap it and let it sit overnight, then just rinse it out.

Squirt some oven cleaner into it. Slosh it around, dump it, then let hot water run into it for a few minutes.

Dump the hot water and leave it to drip and drain, upside, down til it dries.

You beat me to it....That was the way I was taught to clean glass coffee pots when I got my first job working at a restaurant years ago. It works great.

Commercial espresso machine cleaner is just TSP and it works great. A lot cheaper to buy it at the hardware store than from the restaurant suppliers.

At the burger joint I workded at way longer ago than I care to admit, when we boiled the coffe pots dry we swished some ice and a bit of bleach around, that did the trick. That was for the glass carafe's on our drip coffe machines.
It rinsed out with no detectable chlorine odor.

Same thing I have always done with my stainless, you have to be aware though, you get to much in there, your going to have a mess in the kitchen and your wife might not like you very much, but it works very well, experiment outside in a plastic butter container to get the right mix and DON"T put the lid on the thermos!

:eek:

My wife says she used coffee pot cleaner on mine, then rinsed several times.

I use the baking soda and bottle brush. Then I fill it with boiling water and 1/4 cup bleach let it soak for 10 minutes then rinse out with hot water a couple of times. The bleach does final clean and sanitizes it.

Okay, so I brought my dirty thermos in last night. My wife was in the kitchen and watched me dump in a bunch of crushed ice and rock salt. I put the lid on and gave 'er a good shake (thermos, not wife). Just as she was about to ask "What in the world are you doing?", which she frequently does with good reason, I rinsed it out and showed her the shinier than new lining. "Wow" she exclaimed. "Where'd you learn that trick?" I smiled. She said "Never mind.";)

Could just be that you lose capacity with a 1/4" build up on the walls of the thermos :D:D
