Best Way to Unclog a Toilet: 6 Methods That Actually Work

Quick Answer: Most toilet clogs clear with a flange plunger in under two minutes. If the plunger fails, a toilet auger (closet snake) is the next best tool. The six methods below go from easiest to most involved — work through them in order before calling a plumber.

Before You Start

Stop flushing. Each flush adds more water to a bowl that has nowhere to drain and risks overflowing onto the floor. If the bowl is near the brim, bail out some water with a cup before you start. Lay old towels around the base.

Method 1: Flange Plunger

Best for: The majority of standard toilet clogs.

A flange plunger — the kind with a rubber cup that folds down into a cone shape — seals against the toilet drain opening. A flat-bottom cup plunger is for sinks and will not create adequate suction in a toilet.

How to use it: Place the flange into the drain hole and push firmly to seal. Use slow, steady up-and-down strokes — 10 to 15 cycles — keeping the seal intact. Pull up sharply on the final stroke to break the clog loose. Test with a flush. Repeat two or three rounds if water drains slowly but does not fully clear.

Method 2: Hot Water and Dish Soap

Best for: Soft clogs — tissue paper, small debris — when a plunger is not available.

Squeeze several tablespoons of dish soap into the toilet bowl. Add a half gallon of hot (not boiling) water poured from waist height. Let it sit for 15 to 20 minutes. Never use boiling water — it can crack the porcelain bowl.

Method 3: Toilet Auger (Closet Snake)

Best for: Objects lodged in the trap, clogs the plunger cannot reach, stubborn paper clogs.

A toilet auger is a 3-to-6-foot cable with a rubber sleeve that protects the porcelain from scratching. Insert the cable into the bowl drain, rotate the handle clockwise while feeding the cable forward, and work it past the trap curve. When you feel resistance, rotate to break the clog or hook and retrieve an object. Pull back slowly and flush.

Method 4: Baking Soda and Vinegar

Best for: Mild build-up clogs when no plunger is available.

Pour one cup of baking soda directly into the bowl, followed by one cup of white vinegar. Let it sit for 30 minutes, then flush. This method does not work on solid foreign objects or serious blockages.

Method 5: Enzyme Drain Cleaner

Best for: Slow drains caused by organic build-up — not an emergency fix.

Enzyme-based cleaners break down organic matter using biological agents rather than harsh chemicals. Safe for all pipe materials and septic systems. Not suitable for a completely blocked toilet.

Method 6: Call a Professional Plumber

Best for: Anything the first five methods did not resolve, recurring clogs, or suspected foreign objects.

If a toilet clogs repeatedly after clearing — every few weeks without flushing anything unusual — the problem is not inside the toilet trap. A camera drain inspection will identify whether root intrusion, a pipe belly, or deep build-up is the actual cause.

A recurring clog at a single toilet points to a clogged drain repair need. Multiple fixtures running slow at once means a main line problem — see the guide on main sewer line clogs to understand the difference.

When Not to Plunge

Stop and call a plumber if:

• You know or suspect a foreign object is lodged in the trap — plunging can push it deeper

• Multiple toilets or drains in the house are backing up at once

• Sewage odors are coming from drains throughout the house

• The toilet has overflowed with sewage — this is a health hazard and a main line problem
