Eco Unclogging

$8.39, ecos.com
Mix the sand-like granules from the bottle with warm water and pour it down the problem pipe. After 24 hours, flush with water and voila—a cleared drain. It’s biodegradable, non-toxic, and works pretty well to unclog that pesky plug.

Bio-Flow
$19.50 (1 gallon), greenchem.com
Total Solutions’ Bio-Flow contains enzymes and bacteria that help break down grease and food in your drain. It works well on clogged sinks while deodorizing the area with a minty scent. The ingredients can irritate your eyes and skin, though, so make sure to avoid splashing it as you pour.

CLR
$9.99, jelmar.com
This liquid is the result of a partnership between CLR and the EPA’s Design for the Environment program, meaning it’s an eco-friendlier option than most commercial products. It seems to be the best bet for more serious clogs, plus it comes with a money-back guarantee.

Liquid-Plumr: Power Jet
$6.29, liquid-plumr.com
This drain cleaner is also free of harsh chemicals because it uses a jet of liquid and air to blast out clogs It works surprisingly well for minor clogs that cause slow drainage. Take note: The container can be difficult to recycle, depending on local regulations.

Drainbo Natural Drain Cleaner
$7.99, drainbo.com
We love the pun-y name of this non-toxic liquid, which contains only natural ingredients. Its eco appeal makes it worth a shot for slow drains, but, unfortunately, it doesn’t work very well for serious blockages.
