I've used the stainless travel cups for hot beverages for years. The Contigo brand has worked great, in that respect. Mine is used for coffee.
Considering I like the Coffeemate French Vanilla, the sugars tend to build over time, and grow into an almost caulk appearance and texture.
Once a week I thoroughly clean the lid and inside with a toothbrush, and disassemble to clean as needed.
I have a 20oz, that's somewhat of a challenge to get "clean" deep down towards the bottom.
Today was cleaning time, and while rinsing after using a nylon bottle brush, I noticed coffee sludge on the sides. The nylon brush wasn't working so great.
I grabbed a stainless frosting knife used to spread frosting on cakes, and scraped the sides. What scraped off reminds me of burnt oil found inside a tired engine. As thick as a fingernail.
It was nasty. Rinse/scrape a bit more, and eventually back to bare stainless. My coffee tastes a LOT better, can you imagine?

So it comes to mind that a proper brush, brass or stainless bristle would fill the need and make cleaning a little more effortless.
Something, almost like a cylinder hone, but not so much.

What's your solution to cleaning the cups effectively?
I had a vision of a 1/2 cup or so of stainless BB's and water, swirling the wall inside.
*no cleaning agents or soaps are ever used*

Clorox Cleanup spray, swirled around, followed by a run thru the dishwasher, once a week. Works a charm.

Mind that we normally give our thermoses and travel mugs a “preheat” with boiling water before loading up for the day. That is what I think really cuts down on the glop.

Other upside to preheat is a correct temp refill as needed almost the entire shift.

2nd for baking soda and vinegar - cleans well, removes tough stuff like mineral stains from hard water, etc. Bleach and abrasives can damage the surface. I use regular dish soap on mine until a more thorough cleaning is needed.

Never clean a coffee cup. You worked hard for that flavor, why waste it?



P
This ^^^ has been my thoughts for years.
I should have taken a few pictures. It was caked, pretty solid.
I literally had to scrape it off the sides and bottom.
Like, how the BBQ grill gets after using it all summer. LOL!!
 
i got a hydroflask for my birthday in april. only ever have used it for ice water. havent cleaned it other than the day i got it. i know this is a little off topic but when im done with my camelbak bladders for the year, i wash them then put them in the freezer to prevent bacteria from growing then rinse them out when i go to use them again

Got the same thing with the same beverage and condiments, never had any of the issues spoken of, but then again I rinse it out everyday.... ;)
