Bring back your sink! First wet the bottom and sides of your sink, and then make sure to plug the drain! Take a small amount of baking soda and lightly coat the bottom. Begin to scrub with a sponge, and much of the grim will start to loosen! Once you notice a difference, add some hydrogen peroxide to your sponge and keep scrubbing. Once you have scrubbed the whole sink (you will notice many of the scratches have disappeared) let it sit for 15-20 minutes, rinse and youre done!
