We’ve all been there—you flush the toilet, and instead of everything swirling away as it should, the water starts rising ominously. Panic sets in. You don’t have a plunger, and the idea of calling a plumber over a simple clog feels excessive.

Then you remember a hack you saw online: dish soap can unclog a toilet. But does it really work? We decided to put this viral trick to the test—here’s what happened.

Why Would Dish Soap Work on a Clog?

Before diving into our experiment, let’s break down the science behind this hack. Dish soap is designed to break down grease and grime, making it a slippery lubricant. The theory is that pouring it into a clogged toilet can:

  1. Loosen the blockage – The soap’s slippery consistency may help dislodge stuck debris.
  2. Break down grease – If the clog is caused by oils or fatty substances (like from food waste), the soap’s degreasing power could help dissolve it.
  3. Create movement – When combined with hot water, the soap may help push the clog through the pipes.

But does reality match the theory?

Our Experiment: Testing Dish Soap on a Clogged Toilet

To get real answers, we simulated a common toilet clog (using toilet paper and organic waste—no harsh objects!) and tried the dish soap method. Here’s how it went:

Step 1: Pour in the Dish Soap

We added ½ cup of liquid dish soap directly into the toilet bowl. We let it sit for 10 minutes to allow the soap to coat the pipes and start breaking down the clog.

Step 2: Add Hot (Not Boiling) Water

After the soap had time to work, we poured a gallon of hot water (not boiling, as extreme heat can crack porcelain) from waist height into the bowl. The force of the water helps push the clog through while the soap reduces friction.

Step 3: Wait… and Flush

We waited another 10-15 minutes, then flushed.

The Results: Did It Work?

✅ For minor clogs (mostly toilet paper or soft waste):

  • Success! The soap and hot water combo helped break down the material, and the toilet flushed normally afterward.

⚠️ For tougher clogs (thick paper, wipes, or solid objects):

  • Partial success. The water level lowered, but a second round was needed.
  • Not a miracle fix. If the clog is deep or caused by non-dissolvable items (like toys or sanitary products), dish soap won’t help.

❌ For severe blockages:

  • No effect. If the clog is deep in the pipes or caused by something hard, a plunger or auger is still necessary.

When Should You Try the Dish Soap Hack?

This method is best for:
✔️ Soft, organic clogs (toilet paper, light waste)
✔️ Emergencies when you don’t have a plunger
✔️ Preventative maintenance (occasional use can help keep pipes clear)

When Should You Skip It?

✖️ If the clog is caused by non-flushable items (wipes, toys, feminine products)
✖️ If the toilet is completely backed up (use a plunger or call a plumber)
✖️ If you’ve already tried and failed (soap won’t fix a major blockage)

Final Verdict: Yes, But With Limits

Dish soap can help unclog a toilet—if the blockage is minor and made of dissolvable materials. It’s a great first attempt before resorting to harsh chemicals or calling a plumber. However, for tougher clogs, keep a plunger handy!
