If your drain’s backed up, you’ve probably stared at bottles of Drano, Liquid-Plumber, or Green Gobbler wondering which one actually works. Here’s the truth: plumbers don’t use those household products.

So What Liquid Do Plumbers Use?

Clogged shower drain being treated with Javelin Tub & Sink | Javelin Tub & Sink TreatmentProfessional plumbers reach for high-powered drain openers made with strong active ingredients like sodium hydroxide—not watered-down retail formulas. One of the most trusted professional options is Javelin Tub & Sink Treatment. It’s what pros use on the job, and now it’s available to anyone.

Sodium Hydroxide: The Real Clog Killer

Most people don’t realize that the ingredient that actually clears hair and grease is sodium hydroxide (lye). The big brands? They use small, diluted amounts—barely enough to make a dent in real blockages.

Here’s how they compare:

Product Sodium Hydroxide (%)
Javelin Tub & Sink 40%
Drano Max Gel <5%
Liquid-Plumber <5%
Green Gobbler <15%
Javelin contains more than double—and sometimes eight times—the active ingredient used in retail drain cleaners.

That’s why plumbers trust it. And now, homeowners and facility managers can too.

Here’s what makes Javelin different: it doesn’t just unclog your sink—it coats the inside of your pipes, breaking down leftover buildup over the next few days. Your drain keeps getting cleaner even after the treatment. Retail products can’t do that.

Bonus Use: A/C Condensate Lines

Got central air? Javelin Tub & Sink Treatment also works great in A/C condensate lines—the narrow tubes that often back up and leak in summer. One application keeps the line clear and prevents water damage from overflows.

Why Homeowners and Pros Are Switching

If you’ve tried every “best drain cleaner” on the shelf and still ended up calling a plumber, it’s time for a professional-grade solution. Javelin Tub & Sink Treatment is:

  • Used by plumbers nationwide
  • 40% sodium hydroxide power
  • Safe for all pipes: PVC, metal, or cast iron
  • Leaves a protective coating that continues cleaning
  • A/C-safe to keep condensate lines flowing

You don’t need to call a plumber—you just need what they use.


Final Word
