Washing soda is a product that can be used not only for laundry, but also to unclog drains. It is similar to baking soda, but stronger. Washing soda has a high alkaline content yet it is not caustic or damaging to pipes. Furthermore, it is much safer to use than commercial products to unclog drains because of its lack of harsh chemicals. If your drain is clogged, opt for the more natural method to clear it by pouring washing soda down the drain. Washing soda can be found in most supermarkets in the laundry aisle.


Step 1

Boil 3 cups of water on the stove. Remove it from the stove and carry it to the clogged drain location.

Step 2

Pour 1 cup of washing soda directly into the drain. Allow it to settle for about five minutes.

Step 3

Pour the boiling water down the drain to push the washing soda through the clog. Wait one minute and the drain should be unclogged.

Step 4

Repeat this process two to three times if the drain is still clogged, pouring 1 cup of washing soda to 3 cups of water each time.


Step 5

Pour 1 cup of white vinegar down the drain if it is still clogged. The acid in the vinegar will neutralize the washing soda. You will notice some foaming, which is normal. The drain should now be completely unclogged.


Pour a quarter-cup of washing soda down the drain and flush with water at least once a week. This will keep the drain clear and prevent it from clogging in the future.
