DO THIS IN THE SINK - Put a tablespoon or two of baking soda in first, then a half a cup of cheap household vinegar, and watch it bubble up. Wait for the foaming action to subside.  Swirl the mixture around making sure all stained areas are covered with mixture.  Let it sit for 5-10 mins.  Then pour it out and rinse with tap water thoroughly. Let dry before refilling.
