How do you remove the coffee taste from a travel mug?
I have several travel mugs that I often fill with coffee and take with me in the car. The problem is that the cups quickly absorbed the taste of the coffee. Now if I put any other beverage, like tea, in the mugs all I can taste is stale coffee. I do wash my dishes very well with soap and water, so that is not the problem. It is just that the coffee is so strong I guess? Anyway, Can anyone please tell me how to remove this stale coffee taste from my travel mug?
Use some baking soda and vinegar – it will make a "volcano" effect first. Fill the mugs and then just leave it and let it sit in the cups overnight. That should take care of it.
