Washing Soda to Unclog Drains

No lye, you can keep your drains from clogging a kinder and gentler way.

Washing soda is an excellent choice for helping drains stay clear because while it is alkaline—a pH of 11—it isn’t as caustic and damaging as the commonly used lye-based commercial product.

Ideally, use washing soda on your drains once a week to keep them clear. Just pour 1/4 cup or so down the drain, and then flush with water.

Washing soda is found in the laundry section of the supermarket. You can use baking soda instead by pouring 1 cup of baking soda down the drain, followed by three cups of boiling water.

The boiling water will change the chemical composition of baking soda to become more alkaline like washing soda. If you already have a clog, try pouring 1 cup of washing soda (or baking soda) down the drain followed by three cups of boiling water. Repeat two or three times.

If you still have a clog, try pouring down 1 cup of vinegar. Being an acid, the vinegar will neutralize the washing soda or baking soda and there will be some foaming and gurgling, but sometimes this agitation is all that is needed in the end to dislodge the grime.

"Washing soda" is better known as Boraxo or 20 Mule Team Borax.
