Which Drain Cleaner Works Better?

Over the past eight months, I had two clogs in my shower drain — both caused by a combination of hair and soap scum.

Green Gobbler versus Drano Performance

I used Drano Dual Force Foamer Clog Remover for the first clog and Green Gobbler Liquid Hair & Grease Clog Remover for the second.

With both Drano and Green Gobbler I poured the liquid down the drain and waited one hour before flushing with hot water.

So, which product worked better?

I wish there was a clear winner, but the truth is that both completely removed the clogs and restored the drain. There wasn’t any noticeable difference in performance.

The only thing noteworthy is that Green Gobbler’s dual-chamber bottle has two pre-measured applications, which takes the guesswork out of using this product. With Drano, you can either pour the whole bottle or estimate half. 

There are a couple of important factors to note about my test.

First, the drains and plumbing were the same, and both caused water backup. But there is no way to replicate the exact clog twice. So, there’s no fool-proof way to know if the clog I cleared with Drano was more or less severe than the one I cleared with Green Gobbler.

Second, both brands also offer several different drain cleaners, so I don’t know whether the results would have been different if I used other products.

The key takeaway is that both brands are easy to use and highly effective.

Honestly, I wasn’t surprised by my findings. Both brands are best-sellers and have overwhelmingly positive reviews (Drano reviews, Green Gobbler reviews). And both offer a money-back guarantee, so if you’re not 100% satisfied with the results, you get a full refund.

What Others Are Saying

My test proved that Drano and Green Gobbler both get the job done. But that was only one example. Let’s look at how each brand stacks up, according to other experts.

In Bob Vila’s roundup of the best drain cleaners for hair, Green Gobbler Liquid Hair and Grease Remover was named the best overall due to its ability to dislodge pesky clogs. Drano Max Gel came in at number three for being the “best bang for the buck” since it can dissolve hair and soap scum in minutes.

In Good Housekeeping’s list of the best drain cleaners, Drano Max Gel was named the best overall drain cleaner. Green Gobbler Drain Opening PAC’S came in at number five as the best single-use drain cleaner.

The Spruce awarded Drano Max Gel as the best overall drain cleaner due to its heavy-duty cleaning ability. Green Gobbler Garbage Disposal & Drain Cleaner came in at number five as being the best for cleaning your garbage disposal.

The Chicago Tribune named Green Gobbler Liquid Hair and Grease Remover the best overall drain cleaner. They praised its odorless, non-flammable, and biodegradable formula and its ability to sink through water to dissolve clogs. They also recognized Drano Max Gel for its ability to start breaking down clogs in just 7 minutes. 

Ingredients and How They Work

There are three main types of drain cleaners: enzymatic, caustic, and acidic.

Enzymatic drain cleaners are a more gentle choice. Rather than using harsh chemicals to destroy the clog, this type of drain cleaner contains enzyme-producing bacteria that feeds on the clog.

Since enzymatic drain cleaners don’t contain corrosive chemicals, they are believed to be safer on pipes and less of a risk to use regularly. The main downside is that they can take significantly longer to clear a clog than other drain cleaners containing clog-attacking chemicals.

Green Gobbler is an enzymatic drain cleaner. It uses a special blend of eco-friendly ingredients that are non-corrosive and biodegradable. These products are also safe on all types of pipes, including plastic and copper. Since the formula lacks harsh chemicals, it’s unlikely to cause skin, eye, or respiratory irritation.

Drano is classified under the caustic category of drain cleaners. Caustic drain cleaners use alkaline chemicals such as sodium hydroxide to dissolve the clog. This type of drain cleaner is ideal for food, grease, and soap scum clogs because the formula will cut right through the thick buildup. It’s considered safer than acidic cleaners but still contains harsh chemicals, so you should wear protective clothing while handling it.

Most Drano products are made of a blend of sodium hydroxide, sodium metasilicate, and sodium hypochlorite (bleach). These ingredients create heat, which prevents the clogs from sticking to the pipe’s sides.

Lastly, acidic drain cleaners are made with sulfuric or hydrochloric acid. They’re ideal for heavy-duty clogs caused by hair, food, grease, soap scum, and even paper clogs. You shouldn’t use them on metal or old pipes as it can cause damage. You must wear protective clothing when handling this type of drain cleaner.

Let’s quickly review the main ingredients in Green Gobbler and Drano:

Green Gobbler Ingredients:

First, let’s look at Green Gobbler enzyme drain cleaner (view ingredients here).

  • A defoamer is used to prevent the formula from foaming up.
  • Monopotassium phosphate and Dipotassium phosphate act as buffers.
  • Viable bacteria culture is the active ingredient and acts as the cleaning agent.
  • Fragrance

Drano Ingredients:

Now, let’s look at Drano Dual Force Foamer (view ingredients on WhatsInsideSCJohnson.com).

  • Water provides a liquid base for the formula.
  • Sodium hypochlorite (bleach) breaks down clogs and removes mold and mildew.
  • A Proprietary Surfactant Blend acts as the cleaning agent to remove dirt and loosen other matter so it can be rinsed.

  1. This was very helpful, as someone suggested Green Gobbler to me. My problem is the odor coming out of the bathroom sink; there is no clog. Water goes through quickly. What may be causing the odor?
