An inexpensive, natural homemade solution to remove clogs simply requires baking soda, vinegar, and boiling water. Pour one to two cups of baking soda followed by one to two cups of vinegar down the drain. Immediately cover the drain with some type of stopper so that the solution will not erupt up and out. After about 30-45 minutes, slowly poor the boiling water down the drain. If it doesn't unclog after one attempt, try a couple more times.
