Tools you may need

Gather a few simple tools first:

• Plunger (cup or sink plunger)
  
• Rubber gloves and old towels
  
• Bucket and screwdriver
  
• Toilet auger or sink snake (hand auger)
  
• Wet/dry shop vacuum (if you have one)
  
• Vinegar, baking soda, and a kettle for hot water
  

First steps: keep safe

Wear gloves and keep kids and pets away. If water spills, wipe it up fast. Do not mix cleaners like bleach and drain chemicals. That makes bad fumes. If you smell gas or see big leaks, leave and call a pro.

Method 1: The plunger trick

Plungers work for many sink and shower clogs.

1. Fill the sink or tub so the plunger head is covered.
   
2. Place the plunger over the drain and make a tight seal.
   
3. Push down and pull up fast for 15–20 pumps.
   
4. Pull the plunger off to see if water drains.
   
   Repeat a few times if needed. For double sinks, plug the other drain while you plunge.
   

Method 2: Hot water and dish soap

This is a safe, cheap trick for grease clogs.

1. Pour a cup of liquid dish soap into the drain.
   
2. Heat a pot of water until very hot but not boiling.
   
3. Pour the hot water into the drain in two slow pours.
   
4. Wait a few minutes and run water.
   
   This melts grease and helps push it down.
   

Method 3: Baking soda + vinegar (natural fizz)

This combo can clear mild clogs and freshen the drain.

1. Pour 1 cup baking soda down the drain.
   
2. Pour 1 cup white vinegar after it.
   
3. Cover the drain for 5–10 minutes to hold the fizz.
   
4. Flush with hot water.
   
   If it still runs slow, try again or use a snake next.
   

Method 4: Use a hand auger / drain snake

A snake works for tougher clogs under the trap or deeper in the line.

1. Remove the drain cover if needed.
   
2. Feed the snake into the drain and turn the handle clockwise.
   
3. When you feel resistance, push and pull while you turn.
   
4. Pull out the snake slowly; it may bring up hair or gunk.
   
5. Run hot water to flush the loosened debris.
   
   A toilet auger is best for toilets. Do not use a wire hanger, it can scratch pipes.
   

Method 5: Remove and clean the P-trap (under sink)

This works when the clog is in the trap under the sink.

1. Put a bucket under the trap to catch water.
   
2. Loosen the slip nuts with pliers or by hand.
   
3. Remove the trap and empty gunk into the bucket.
   
4. Rinse the trap and reassemble.
   
5. Run water to check the flow.
   
   If you see signs of damage or slow flow after reattaching, call a plumber.
   

Method 6: Wet/dry vacuum (strong suction)

A wet/dry vac can pull out clogs in sinks or tubs.

1. Set the vacuum to liquid mode.
   
2. Make a tight seal around the drain with the hose or a rag.
   
3. Turn the vac on to suck the clog up.
   
   This can work for tough things near the drain opening.
   

Method 7: Enzyme drain cleaners (safe slow fix)

Enzyme cleaners use natural enzymes to eat organic clogs.

• Good for hair, soap, and food build up.
  
• They work overnight and are safe for pipes and septic systems.
  
• Follow product directions and give them time to work.
  

What NOT to do: safety first

• Do not mix bleach and vinegar or bleach and drain cleaners.
  
• Do not dump boiling water on plastic pipes, use very hot, not boiling.
  
• Avoid chemical drain cleaners on toilets and older pipes, they can harm pipes and seals.
  
• Don’t force tools without a good view, you can push the clog deeper.
  

How to prevent future clogs

• Use a drain strainer to catch hair and food.
  
• Do not pour grease down the sink. Wipe pans with a paper towel first.
  
• Run hot water after oily or greasy jobs.
  
• Clean shower drains monthly with baking soda and hot water.
  
• For toilets, only flush toilet paper and human waste.
