TL;DR: Professional plumbers clear tough drain clogs using plungers, drain snakes, plumbing augers, and chemical drain cleaners depending on the severity of the blockage. Store-bought products like Drano and Green Gobbler can help with minor clogs, but a licensed plumber has the tools to handle anything your drains throw at them. If you are in the Triangle area of North Carolina, Drain Express can clear your drains right the first time.
What do professionals use to clear tough drain clogs?
Professional plumbers use a combination of plungers, drain snakes, plumbing augers, and chemical drain cleaners to clear tough clogs, selecting the right tool based on where the blockage is and how severe it has become. Up to 15% of American homeowners try to handle clogs on their own, according to PR Newswire, but a professional like Drain Express brings the right equipment and experience to get the job done without causing additional damage to your pipes.
Plunger
The plunger is often the first tool a professional reaches for. It creates a vacuum seal over the drain opening, then uses pressure to dislodge the blockage. A Drain Express technician will fill the sink with enough water to fully submerge the plunger cup, then pump it vigorously before lifting it sharply to break the seal. That combination of pressure and suction is often enough to free a moderate clog quickly.
Drain Snake
For blockages that a plunger cannot shift, a drain snake is the next step. This flexible metal tool threads down through the drain until it reaches the obstruction. The technician maneuvers the snake past the clog, twists it to hook the material, and pulls it back out through the drain. It is especially effective for clogs caused by hair or grease buildup deep inside the pipe.
Plumbing Auger
A plumbing auger handles deep-seated clogs that a standard snake cannot reach. Similar to a drain snake, the auger has a metal spiral at its tip that latches onto the clog and pulls it free. It is also the right tool when a small object like a piece of jewelry has accidentally fallen into the drain.
Chemical Drain Cleaners
When mechanical tools alone are not enough, a professional may use chemical drain cleaners. These solutions dissolve the blockage through a chemical reaction. A technician pours the cleaner into the drain, allows it time to work, then flushes the pipe with water. Because these chemicals are hazardous, safe handling by a trained professional protects both your pipes and your household.

What is the best drain clog remover?
The best drain clog remover depends on what is causing the blockage: a plunger or drain snake works best for solid obstructions, while a chemical cleaner works better for grease and soap buildup. For clogs that keep coming back or are deep in the line, a professional plumber with a drain auger will outperform any product you buy off a shelf.
What is the best drain cleaner?
The best drain cleaner for most household clogs is one matched to the type of blockage you are dealing with: enzyme-based cleaners work well for organic buildup over time, while caustic or oxidizing cleaners break down tougher grease and soap clogs faster. No chemical cleaner, however, replaces the effectiveness of a trained plumber using mechanical tools for serious blockages.
What is the best drain unclogger for stubborn blockages?
For stubborn blockages, the best drain unclogger is a professional-grade drain snake or plumbing auger used by a licensed plumber, because these tools physically remove the obstruction rather than just breaking it apart. Chemical products can soften a clog but often leave residue behind that causes the same problem to return within weeks.
Green Gobbler vs Drano: which is better?
Green Gobbler and Drano both clear common household drain clogs, but they work differently: Drano uses sodium hydroxide (lye) to generate heat and dissolve blockages, while Green Gobbler uses a monoethanolamine-based formula that is marketed as safer for pipes and the environment. The better choice depends on your pipe type and the nature of the clog.
| Feature | Green Gobbler | Drano |
|---|---|---|
| Active ingredient | Monoethanolamine | Sodium hydroxide (lye) |
| Works best on | Grease, hair, soap scum | Hair, grease, soap buildup |
| Pipe safety | Marketed as safer for pipes | Can damage older or plastic pipes with repeated use |
| Environmental claim | Marketed as more eco-friendly | Standard chemical formula |
| Best for | Routine maintenance clogs | Moderate to stubborn clogs |
For either product, follow label directions carefully. If one application does not clear the clog, stop and call a professional rather than pouring additional product into a blocked drain.
Is Drano or Liquid-Plumr better?
Drano and Liquid-Plumr are closely matched chemical drain cleaners that both use sodium hydroxide as a key ingredient, so neither has a clear advantage for most common household clogs. The real difference is in secondary ingredients and gel formulations that affect how long the product clings to the pipe walls. If neither product clears the clog after one use, the blockage is likely too deep or too solid for a liquid cleaner to handle on its own.
What is a drain auger?
A drain auger is a plumbing tool with a flexible metal cable and a corkscrew-shaped metal tip that latches onto and pulls out deep clogs from inside a pipe. It works similarly to a drain snake but is built for tougher, deeper blockages and is especially useful for retrieving solid objects like jewelry that have fallen into a drain. Professional plumbers use motor-driven augers that can reach much farther into a pipe than any hand-cranked tool a homeowner can buy.
How do you clear a clog in your plumbing system?
You clear a clog in your plumbing system by working from the least invasive method to the most: start with a plunger, move to a drain snake if the plunger fails, try a chemical cleaner for grease-based clogs, and call a licensed plumber if none of those steps work. Trying to force a clog out with excessive pressure or too many chemical products can damage your pipes and make the problem more expensive to fix.
Here is a step-by-step approach professionals recommend:
- Fill the sink slightly so the plunger cup is submerged, then plunge firmly several times.
- If the plunger does not clear it, thread a drain snake into the drain until you feel resistance.
- Twist and pull the snake to hook and remove the obstruction.
- For grease or soap buildup, apply a chemical drain cleaner according to label directions and flush with water.
- If the clog persists, call a plumber with a motor-driven auger or hydro-jetting equipment.
How do you clear a drain line when the clog is really hard?
A hard clog deep in the drain line is best cleared with a plumbing auger, because its spiral metal tip can grip a solid obstruction and pull it out in a way that a plunger or liquid cleaner cannot. If the auger does not reach it or the clog keeps returning, a professional will use a motor-driven snake or inspect the line with a camera to find the exact location of the problem before deciding on the right fix.
Should you use Drano before a snake?
You should use a drain snake before Drano, not after, because Drano sitting in a blocked pipe creates a pool of caustic chemical that can splash back onto your skin when you insert the snake. If you have already poured a chemical cleaner into the drain, wait until the manufacturer says it is safe and flush the drain thoroughly with water before using any mechanical tool. A plumber will always snake first and only consider chemicals for specific types of buildup that mechanical tools cannot remove on their own.
Quick Recap

- Chemical cleaners like Drano, Liquid-Plumr, and Green Gobbler work on grease and soap buildup but should not be used before a snake.
- Green Gobbler and Drano are similar in effectiveness; Green Gobbler is marketed as gentler on pipes.
- Drano and Liquid-Plumr use similar active ingredients and perform comparably on most clogs.
- A plumbing auger is the professional tool of choice for deep or solid blockages and for retrieving dropped objects.
- If store-bought solutions and a hand snake have not worked, it is time to call a professional before the problem gets worse.
Frequently Asked Questions
Can I use a drain snake and Drano at the same time?
No. Never use a drain snake in a pipe that still has chemical cleaner sitting in it. The chemical can splash back and cause serious skin or eye injuries. Snake first, and if you decide to use a chemical cleaner afterward, follow the label directions and flush the pipe completely before using any tools.
How do I know if my clog is too tough for a DIY fix?
If you have plunged the drain, tried a hand snake, and applied a chemical cleaner with no result, the clog is likely too deep or too solid for standard DIY tools. Recurring clogs in the same drain are another sign that a professional inspection is needed to find the real cause.
Will chemical drain cleaners damage my pipes?
Repeated use of caustic chemical cleaners like Drano can weaken older pipes and certain types of plastic pipe over time. Using them occasionally as directed on modern PVC or ABS pipes is generally safe, but they are not a substitute for professional mechanical cleaning when a clog is serious.
What causes drains to clog repeatedly in the same spot?
Recurring clogs in the same drain are usually caused by a buildup of grease, hair, or soap scum that was never fully removed, or by a partial obstruction deeper in the line that DIY methods only partially cleared. A plumber can use a camera inspection to find the exact cause and clear it completely.

Is Green Gobbler safe for all pipe types?
Green Gobbler is marketed as safer for pipes than traditional lye-based cleaners, but you should still check the product label for compatibility with your specific pipe material, especially if you have older cast iron or galvanized steel pipes. When in doubt, a mechanical approach from a plumber is the safest option.
What is the fastest way to unclog a drain?
The fastest reliable method depends on the clog. A plunger can clear a moderate blockage in minutes. A drain snake takes slightly longer but handles tougher obstructions. For the fastest resolution on a serious or recurring clog, calling a professional plumber with motor-driven equipment is the most efficient path forward.
