Experts agree: Drano Max Gel is the best overall drain cleaner because it works quickly to get rid of tough clogs. This reliable and effective cleaner is a thick gel that goes deep in sinks, pipes, and drains to reach the source of the clog and completely dissolve it. Whether the clog is from hair, soap scum, grease, or any other type of residue, this drain cleaner works within 15 to 30 minutes after flushing it with very hot water. While it may take two tries to be fully successful, this cleaner is powerful enough that it will quickly become the first thing you reach for when you need to unclog a drain.
This product is safe to use in showers, sinks, tubs, as well as septic systems, garbage disposals, PVC pipes, and metal pipes—but it's important to note that it's not safe to use in toilets. Like most drain cleaners, Drano Max Gel contains chemical ingredients that can be harmful if swallowed or in contact with the skin or eyes. We also appreciate that Drano Max Gel is reasonably priced, yet it still comes with a money-back guarantee. If it doesn't clear your drain, you can file a claim online for reimbursement.

Unlike other cleaning products, finding drain cleaners made with natural or organic ingredients is quite the challenge. That said, Earthworm’s Drain Cleaner and Buildup Remover was an easy choice as our pick for the best natural drain cleaner. Instead of harsh chemicals, this liquid cleaner is formulated with natural enzymes that are still tough enough to break down buildup and dissolve moderate clogs—all without damaging your pipes. It’s ideal for dissolving hair, soap scum, toothpaste, and other organic materials, but it may require a few tries to fully dissolve it.
This product’s best feature might be its aromatic citrus and sage scent that leaves sinks and garbage disposals smelling fresh. Plus, it's available in 32-, 64-, or 128-ounce bottles, so you can find the perfect size to store under your sink.
Overall, this cleaner is a great choice for anyone looking to unclog their drain using safe and natural ingredients, particularly in households with small children or pets. We also like that this drain cleaner is from a women- and family-owned brand.
