Is Drain Cleaner Bad for the Environment?

Drain cleaners that contain corrosive chemicals like sodium hydroxide and sulfates pose a risk to the environment.

These strong chemicals can harm the bacteria in septic systems and can be toxic to various aquatic organisms.

On the other hand, environmentally friendly drain cleaners like the products we mentioned on this list are formulated without harsh chemicals.

Hence, they are generally considered safe for the environment and to a person’s health.

Is Drano Environmentally Friendly?

The thing that makes Drano a potential environmental hazard is because it contains sodium hydroxide.

The fumes it releases can also cause allergies and irritations to someone who is exposed.

And since chemical drain cleaners like Drano are formulated with strong chemicals that attack whatever is clogging your pipes, it can also cause damages to plastic or even metal pipes. 

Now, to be clear, a single use of Drano isn’t likely to cause any issues with your pipes or to your health.

However, due to its harsh chemical contents (as we discussed above), prolonged usage of Drano might cause allergies, skin irritations, and even damages to your plumbing systems.

Is it Safe to put Baking Soda and Vinegar down the Drain?

The short answer is, Yes.

The baking soda and vinegar solution is a widely known eco-friendly alternative to chemical drain cleaners.

When combined, vinegar and baking soda create carbon dioxide and water bubbles that seeps through clogs and blockages and breaks it up into small pieces that can be easily flushed away.

Flushing the baking soda and vinegar solution using boiling water also helps remove unwanted goop out of the pipes, and unclogs drains.

Unfortunately, while baking soda, vinegar, and boiling water can help clean drains naturally, they might not be strong enough to get rid of more challenging clogs.

So if you need something stronger to open up your drains, go ahead and try any environmentally friendly drain cleaners in this list and share your experience with us.

Do Environmentally Friendly Drain Cleaners Work?

Yes. While chemical drain cleaners use strong, corrosive chemicals to dissolve clogs, environmentally friendly drain cleaners utilize live bacteria, enzymes, and natural ingredients to get the job done.

What is the Best Drain Cleaner?

In our opinion, the best drain cleaners are the ones that can effectively remove clogs and maintain a steady flow of fluid in your drainage system without causing harm to anyone’s health and the planet.
