I wrote about my Thermos King stainless steel travel mug about almost five months ago. I still love the hefty, super high-performing, zombie-killing-in-a-pinch insulated coffee mug.
I have recommended several of these mugs and have purchased a few as gifts. One of my readers asked how to clean the lid, as the lid is a notorious sticking point for travel mugs. I decided to put together a video about it, as well as share some ownership / cleaning insights I’ve stumbled across.
- Clean the external part of the lid and the interior as often as you want. I use a nylon-fiber scrub brush you can buy for about a dollar. This is the part of the mug lid where you put your mouth. I also wipe it down every few days with a damp, clean cloth.
- Disassemble the lid and clean it on a regular, but not daily basis. I want to minimize wear and tear on the many plastic threads on my Thermos King. The lid has several plastic threads, and their gradual wearing down may lead to leakage. I disassemble the lid to my mug about once a week.
- Remove and clean the large main gasket sparingly. My King travel mug was leaking about a month ago. I thought that the seals had failed, and that my initial assessment of the mug’s durability was wrong. Turns out that a coffee ground had found its way into the gasket and kept it from sealing properly. A quick disassembly and rinse with tap water cleared everything up. However, I am concerned about deforming the gasket with repeated removal and reassembly.
- Hand wash everything. I’m paranoid about it I guess, but I’ve ruined a few cheaper travel mugs by putting them in the dishwasher. I think the heat starts to deform the plastic just enough to where it no longer keeps a seal.
Here’s a video I put together in case you want to see how it all works:
The King travel mug by Thermos is still kicking, despite the brand label coming off about two months ago. I love this thing, and I think you should give it a shot.
