How to clean a stainless steel coffee mug?
My favorite stainless coffee mug is getting so flavorful that I think I should give it a deep clean. Add 2 Tbsp baking soda into mug; Pour 1/4 cup white vinegar into mug, enjoy watching the bubbles; Put the lid on, gently turn the mug so that the inside is rinsed with the solution; With a dish sponge, clean the inside becomes so easy, and the coffee stains come off effortlessly; Raise mug with hot water. It took me 5 minutes to get it as shinny as new. A quick and green way to clean!
