What Can I Use at Home to Unclog a Drain?

7 Ways to Unclog a Drain at Home

A clogged drain is one of the most common plumbing problems homeowners face. Before reaching for harsh chemical drain cleaners (which can damage your pipes), try these safer and often more effective home remedies.

1. Baking Soda and Vinegar

This classic combination creates a chemical reaction that helps break up clogs.

How to use it:

1. Pour 1/2 cup of baking soda down the drain
2. Follow with 1/2 cup of white vinegar
3. The mixture will foam and bubble — this is normal and means it's working
4. Cover the drain with a plug or cloth to contain the reaction
5. Wait 30 minutes to 1 hour
6. Flush with hot water

This method works well for organic buildup, soap scum, and minor grease clogs. You may need to repeat 2-3 times for stubborn blockages.

2. Boiling Water

The simplest method — and often surprisingly effective for grease clogs.

How to use it:

1. Boil a full kettle or large pot of water
2. Pour it slowly down the drain in 2-3 stages
3. Wait a few seconds between each pour to let the hot water work

Important: Do NOT pour boiling water into PVC pipes or on porcelain fixtures — the heat can damage them. Use very hot (not boiling) tap water instead.

3. Salt and Hot Water

Salt acts as a mild abrasive that helps dissolve grease and buildup.

How to use it:

1. Pour 1/2 cup of table salt down the drain
2. Follow with boiling water (if safe for your pipes)
3. Let it sit for a few minutes, then flush with hot water

For tougher clogs, combine 1/2 cup salt with 1/2 cup baking soda, let sit overnight, then flush with hot water in the morning.

4. Dish Soap and Hot Water

Particularly effective for grease clogs in kitchen sinks.

How to use it:

1. Squirt a generous amount of dish soap down the drain
2. Pour boiling water down in stages
3. The soap acts as a lubricant to break up greasy blockages

5. Plunger

A plunger creates suction and pressure that can dislodge many common clogs.

How to use it:

1. Fill the sink with enough water to cover the bottom of the plunger cup
2. Place the plunger over the drain, creating a tight seal
3. Push down firmly, then pull up quickly — repeat 15-20 times
4. Check if water starts draining
5. Repeat if necessary, increasing force with each set

Tip: Use a flat-bottom plunger (cup plunger) for sinks. The flanged plunger is designed for toilets.

6. Plumbing Snake (Drain Auger)

For clogs that won't respond to chemical methods, a drain snake physically removes the blockage.

How to use it:

1. Insert the snake into the drain opening
2. Rotate the handle clockwise while pushing it further into the pipe
3. When you feel resistance, you've hit the clog
4. Continue rotating to break up or grab the blockage
5. Pull the snake out — the clog should come with it
6. Run hot water to flush remaining debris

You can buy a basic hand-crank drain snake at any hardware store for $15-$30.

7. Wire Hanger (Emergency Method)

If you don't have a snake, a wire coat hanger can work in a pinch.

How to use it:

1. Straighten the hanger and create a small hook at one end
2. Insert it into the drain
3. Fish around to pull out hair, food, or debris
4. Be gentle to avoid scratching or damaging pipes

What NOT to Put Down Your Drain

Many clogs are preventable. Avoid putting these down your drains:

• Grease and cooking oil — solidifies in pipes
• Coffee grounds — accumulates and creates blockages
• Hair — use a drain screen to catch it
• Fibrous foods — celery, potato peels, onion skins
• "Flushable" wipes — they don't break down like toilet paper

When to Call a Professional Plumber

Home remedies work for most minor clogs. But call a plumber if:

• The clog keeps coming back
• Multiple drains are clogged simultaneously (possible sewer line issue)
• You hear gurgling sounds from other drains
• Water backs up in unexpected places
• You smell sewage
• You've tried multiple methods without success

Persistent or recurring clogs often indicate a deeper problem — tree root intrusion, a collapsed pipe, or main sewer line blockage — that requires professional equipment like a sewer camera inspection to diagnose.
