Drano Max Gel is the best clogged drain cleaner. It penetrates deeply into your drains, breaking down even the most stubborn clogs in as little as 15 minutes or overnight. While it works well for bathroom sinks, kitchen sinks, and garbage disposals, it's not recommended for use in toilets due to potential heat damage from chemical reactions.

Overall, Drano Max Gel Clog Remover proves effective on various types of clogs, including standing water, hair, and soap scum.


2. Zep Drain Defense

Zep Drain Defense is the best drain cleaner for old pipes and is capable of tackling tough clogs, including those in septic systems. Designed to address up to a year's worth of buildup, this formula requires a three-day treatment plan for optimal results. Keep in mind that drains cannot be used for six hours after starting treatment, so it's best applied at night to allow for extended sitting time without disrupting daily activities.

Unlike traditional drain cleaners, Zep Drain Defense relies on enzyme-based technology, making it more environmentally friendly. However, this means it may take longer to break down clogs, and there's a risk of drains becoming re-clogged from broken-down particles.


3. Instant Power Septic Shock

When cleaning your kitchen sink, you may first consider using a chemical drain cleaner. However, safer alternatives are available that are just as effective. Here, we present the best drain cleaner for kitchen sinks:


1. Boiling Water

If your drain is clogged the immediate reaction might be to resort to harsh chemicals or call a plumber. However, one of the most effective and best sink drain cleaner is boiling water. Pour it slowly into the drain in sections working for several seconds between each pour.


2. Vinegar and Baking Soda

Nobody wants a clogged drain in their kitchen sink. Luckily, there’s a simple cleaning solution that requires only two common ingredients: baking soda and vinegar. 

Pour ½ cups of baking soda and half a cup of vinegar down the drain. Allow the solution to work for 15-20 minutes. When finished, rinse everything with hot water.

Considerations When Purchasing the Best Drain Cleaner

Formulation (Chemical or Natural)

Not all drain cleaners are alike, so it's crucial to consider their formulation. Essentially, there are two types: those with chemicals and those with enzymes. Chemical drain cleaners excel at clearing clogs because their ingredients can break down tough materials like hair. On the flip side, enzyme cleaners are equally effective against clogs but may require multiple uses since they're more natural.


Effectiveness on Stubborn Clogs

Clogs are bothersome, so your drain cleaner must get the job done quickly, preferably in one use. To use a drain cleaner effectively, follow the recommended time for the product to sit. Most cleaners require 15 to 30 minutes, but some fast-acting ones only need 10 minutes.


Safety for Septic Systems

Knowing which pipes (and clogs) your drain cleaner is suitable for is crucial before purchasing. Not all cleaners are suitable for toilet clogs, and using the wrong one could harm your septic system. Biodegradable cleaners are the safest option for septic tank clogs.

Environmental Impact

When choosing the best drain cleaner, consider its environmental impact. Chemical cleaners effectively remove clogs but come with significant drawbacks, including environmental harm.
