Some home remedies for clearing clogged drains include mixing baking soda with vinegar or salt and using boiling water to clear the clog. A home remedy to prevent clogs from forming uses a mixture of baking soda, salt and cream of tartar.
If the clog is not too severe, try pouring 1/2 cup of baking soda down the drain, and then pour 1/2 cup of vinegar. The mixing of the baking soda and vinegar creates a bubbling and foaming action, so lightly cover the drain. Allow the mixture to work for a couple of hours before attempting to run water down the drain.
If the clog is oily and greasy, dump 1/2 cup of salt along with 1/2 cup of baking soda into the drain, and then pour in a teakettle of boiling water. Leave it alone for several hours or overnight to allow the clog to loosen before running the water.
Cleaning drains every week with a mixture of baking soda, salt and cream of tartar can help keep clogs from forming. Mix a cup each of baking soda and salt with 1/4 cup of cream of tartar. To clean drains, pour 1/4 cup of the mixture followed by a cup of boiling water down the drain, wait a few seconds, and then turn on the water.
