No, coffee stains are not permanent. There are a lot of ways to remove them from any surface. While methods may vary depending on the stained surface, it does not change the fact that coffee is not a lifetime tragedy because even normal kitchen condiments like lemon, salt, or baking soda can easily take the coffee stains off different surfaces. There are also stain removers available on the market. But if you want to get rid of them by yourself, it will be a piece of cake.
