Coffee mugs made of stainless steel are preferred for their strength and durability. They keep coffee warm and look like-new for quite a long time.
If you drink coffee from a stainless steel mug quite often, odor and residue may build up over time. You can use inexpensive cleaners to cleanse and deodorize the mug.
First, pour baking soda (2 tablespoons) into an empty mug. Baking soda works as a deodorant.
Add a ¼ cup of vinegar (apple cider or white distilled vinegar).
Once mixed, the ingredients will foam inside the mug. That way, the mug will be deodorized and disinfected.
Next, close the lid and shake the mug for about 5 seconds for the mixture to scrub the interior thoroughly.
Open the lid and pour the mixture. Rinse the coffee mug thoroughly with some hot water. Doing so will remove remnant cleaners from the mug interior.
Wet a clean cloth and use it to wipe the inner surface of the mug. Rinse it again with some hot water.
