Fact or Fiction: Carbonated Beverages Can Unclog a Drain?

If something sounds too good to be true, it usually is. Remember those sneakers that claimed they could tone your legs? So, we’re generally suspicious of any wacky “quick fixes” when it comes to plumbing.

Fact or Fiction: Carbonated Beverages Can Unclog a Drain

A client recently asked us about something they read online – that pouring carbonated beverages such as soda can help clear a clogged drain. Is there any merit to this claim, or is it another one that falls into the too-good-to-be-true category?

Using cola as a drain cleaner

You may be surprised to learn that pouring soda down the drain does work for some clogs. To be specific, you need a dark-colored cola (such as Coca-Cola or Pepsi). This type of carbonated beverage usually contains a good amount of phosphoric acid, which given enough time, can eat away at some types of clogs. Here’s how it would work:

  • First, pour a two-liter bottle of cola down the clogged drain (we recommend the drink be at room temperature, not right from the fridge)
  • Let the soda sit in the drain for a few hours to let the phosphoric acid do its job
  • Flush the drain with hot water, then see if the drain flows properly

Better drain cleaning methods

While the phosphoric acid found in cola can help alleviate some minor clogs, carbonated beverages are certainly not the ideal drain cleaner. Better DIY methods include a baking soda/vinegar mixture, a plunger, or a plumber’s snake. We recommend against using store-bought drain cleaning liquids as they contain harsh chemicals that can be harmful to your plumbing and health.
