1/2 cup (110g) baking soda
1/2 cup (125ml) vinegar
2 quarts (2 liters) water
A slow moving drain can be a harbinger of bigger problems unless it’s dealt with swiftly. But before you pour harsh chemicals down the drain, give this easy, natural formula a try: Start by pouring the baking soda in to the problem drain, followed by the vinegar and let sit for 15 minutes. Meanwhile, bring the water to a boil. After 15 minutes, pour the boiling water down the drain.
Repeat monthly to keep your drain clean and smelling fresh.
