How to Unclog a Toilet When a Plunger Doesn't Work

If your plunger isn't cutting it, don't panic. Here are 5 alternative methods to unclog a stubborn toilet — and when to call for backup.

The Plunger Failed. Now What?

First, make sure you're using a flange plunger (the one with an extended rubber flap), not a cup plunger (for sinks). That alone can make the difference.

Using the right plunger correctly:

  1. Ensure enough water covers the plunger cup
  2. Insert at an angle to avoid trapping air
  3. Push and pull vigorously (the pull is as important as the push)
  4. Repeat 15-20 times before giving up

Still stuck? Try these methods.

Method 1: Hot Water and Dish Soap

Works best for: Organic matter, toilet paper clogs

  1. Remove some water if the bowl is full (wear gloves, use a cup)
  2. Squirt dish soap into the bowl — about 1/4 cup
  3. Add hot water (hot from the tap, NOT boiling — boiling can crack porcelain)
  4. Wait 10-15 minutes — the soap lubricates and the heat softens
  5. Try the plunger again

The soap acts as a lubricant to help things slide through.

Method 2: Baking Soda and Vinegar

Works best for: Partial clogs, organic buildup

  1. Pour 1 cup baking soda into the bowl
  2. Slowly add 2 cups vinegar — it will fizz
  3. Wait 30 minutes for the chemical reaction to work
  4. Follow with hot water
  5. Try flushing

This works similarly to those volcano science projects — the fizzing action can break up the clog.

Method 3: Toilet Auger (Snake)

Works best for: Solid clogs, objects stuck in the trap

A toilet auger (also called a closet auger) is designed specifically for toilets. It has a protective rubber sleeve so it won't scratch the porcelain.

How to use it:

  1. Insert the auger into the bowl, rubber sleeve first
  2. Crank the handle clockwise while pushing
  3. You'll feel resistance when you hit the clog
  4. Keep cranking to break through or hook the obstruction
  5. Pull back slowly — you may retrieve what's stuck
  6. Flush to test

Important: Don't use a regular drain snake — it can scratch or crack the porcelain.

You can buy a toilet auger for $30-50 at any hardware store. Worth having if you have recurring issues.

Method 4: Wet/Dry Vacuum

Works best for: Hard objects stuck in the trap (toys, etc.)

Do NOT use a regular vacuum — only a wet/dry shop vac

  1. Set the vacuum to liquids
  2. Remove water from the bowl
  3. Insert the hose into the drain
  4. Create a seal with a rag around the hose
  5. Turn on — the suction may pull out the obstruction

This is especially effective for toys and other solid objects kids flush.

Method 5: Enzyme Drain Cleaner

Works best for: Slow drains, partial organic clogs

Enzyme cleaners (not chemical) use bacteria to break down organic matter. They're safe for pipes and septic systems.

How to use:

  1. Follow product instructions (usually pour and wait overnight)
  2. Don't use the toilet for 8+ hours
  3. Flush in the morning

Enzyme cleaners work slowly but are good for recurring issues.

What NOT to Do

Don't use chemical drain cleaners (Drano, Liquid-Plumr) in toilets:

  • They can damage the porcelain
  • The chemicals can splash back and burn you
  • They don't work well on toilets anyway

Don't use a coat hanger — you'll scratch the porcelain

Don't keep flushing — you'll overflow the bowl

Don't ignore it — a clog won't go away on its own

When to Call a Plumber

Call if:

  • None of these methods work
  • The toilet clogs repeatedly (might be a main line issue)
  • You suspect a non-flushable object is stuck
  • Water is backing up elsewhere when you flush

A professional has tools and cameras to see exactly what's happening.
