You can put this oozing wonder to work on your clogged drains. Just unscrew the stopper if applicable and remove any hair or other nasty trappings that are right on the surface. Then shake baking soda into the drain. You may need to pack it in with your fingers. Then pour in the vinegar. Let sit for several minutes while the magic happens.
(I recommend skipping the lava red food coloring. This can have an adverse effect on your porcelain ;))
