A clogged sink is one of the most frustrating household problems. Many people instinctively reach for boiling water, hoping it will flush everything away. But pouring hot water into a clogged drain can actually make things worse, especially if grease is involved. Hot water can melt the grease temporarily, only for it to solidify deeper in the pipe.

So what should you do instead?
Here are safe, effective, and homeowner-approved methods to unclog your sink and get rid of foul odors quickly.
1. Rice Water and Baking Soda: A Gentle Natural Cleaner
One surprisingly effective method uses ingredients you already have in your kitchen.
How It Works
Rice water has natural cleaning properties. When mixed with baking soda, it creates a mild abrasive solution that breaks down residue and neutralizes odors.
How to Use It
- Collect a bowl of rice water (the cloudy water from rinsing rice).
- Add baking soda and stir until fully dissolved.
- Pour the mixture down the clogged drain.
- Let it sit and work its way through the blockage.
This is a great option if you want a non-chemical, eco-friendly cleaning method.

2. Dish Detergent and Vinegar: Ideal for Grease Clogs
If your sink is blocked by oil or fat, this combination is incredibly effective.
Why It Works
- Dish detergent cuts through grease.
- Vinegar softens buildup.
- Warm water flushes it all away.
How to Use It
- Mix dish detergent with a small amount of white vinegar.
- Combine with 3 cups of hot (not boiling) water.
- Slowly pour the solution down the drain.
Using Store-Bought Sink Cleaners
If you’re using a commercial sink-cleaning powder, the general method is:
- Dissolve the powder in water.
- Pour the solution into the clogged drain.
- Wait 60–180 minutes, depending on the product and severity of the clog.
- Rinse with clean water.
This method targets tough grease and heavy buildup.

3. Baking Soda, Vinegar, and Salt: A Triple-Action Cleaning Mix
For deeper cleaning and stubborn smells, this method uses a chemical reaction to break down blockages.
How to Use It
- Mix equal parts baking soda and salt.
- Pour the mixture into the drain.
- Follow with 200 ml of white vinegar.
- Cover the drain to keep the reaction inside the pipe.
- Wait 1–2 hours.
- Rinse with hot water.
This combination helps dissolve grime, remove odors, and refresh your drain.

4. Spring Wire or Metal Hook: Best for Solid Blockages
If you suspect the clog includes food scraps, hair, or small objects, a manual removal tool works best.
How to Use It
- Straighten an iron wire or prepare a small spring wire.
- Bend one end into a U-shaped hook.
- Insert it slowly into the drain while rotating.
- Pull it back up to remove debris.
- Repeat until the pipe is clear.
This method physically removes obstructions without chemicals.

5. How to Prevent Future Sink Clogs
Prevention is easier than dealing with a clog. Here’s how to keep your drains flowing smoothly:
- Dispose of food scraps before washing dishes.
- Avoid pouring grease or oil down the sink.
- Use a drain filter net and clean it regularly.
- Occasionally flush the drain with boiling water (only when unclogged) to melt grease buildup.
- Use a wire hook immediately if you drop any large object down the drain.
- Avoid washing large amounts of mud or impurities down the sink.
- Keep a simple drain-cleaning tool at home for emergencies.
Final Thoughts
Unclogging a sink doesn’t require harsh chemicals or expensive tools. With a few simple household ingredients and the right technique, you can clear your pipes, eliminate bad smells, and prevent future blockages.
