Cleaning Stainless Steel Coffee Mugs
My husband uses a stainless steel vacuum container for his coffee. I cleaned it some time ago with baking soda and boiling hot water and some other forgotten ingredient. Can you jog my memory?
The missing ingredient is one of my personal favorites: white or cider vinegar, which helps to clean and deodorize. Put a tablespoon or two of baking soda in first; then a good glug of cheap household vinegar, and watch it bubble up. Put the lid on and shake a few times; pour out and rinse with tap water. Let the thermos dry before refilling.
