I use vinegar to clean my coffee maker — but I get double duty out of it. After I run the vinegar through the coffee maker, while it is still warm, I go to each bathroom sink and pour in ? cup of baking soda and then a little warm vinegar — then I let it sit. Afterwards, I run some fresh water through the coffee maker to rinse out the vinegar, and then pour the warmed water down the drains to rinse out the baking soda and vinegar.
