Blessing 'in a Bottle 12 oz. of White Vinegar 12 oz. of Dawn Dish soap 1 tsp. of Laundry Detergent also known as "kitchen Magic" This stuff will get through anything, make your sink and shower shine like new, and save you when just about nothing else works. The laundry detergent is optional-I add it simply to cover some of the vinegar smell!
