A kitchen sink blockage can occur for several reasons, including:
- Grease and Fat Buildup – Cooking oils and fats solidify in your pipes, creating stubborn blockages.
- Food Scraps – Small food particles, coffee grounds, and eggshells can accumulate over time.
- Soap Scum – Soap residue can combine with grease, forming a sticky clog inside your drain.
- Foreign Objects – Items like cutlery, bottle caps, or dish sponges can accidentally fall into the drain and cause blockages.
If you’re experiencing slow drainage or a complete sink blockage, it’s best to act fast before the problem worsens.
Can I Fix My Blocked Kitchen Sink Myself?
Yes, you can often fix a blocked kitchen sink yourself using simple DIY methods like pouring boiling water, using baking soda and vinegar, or using a drain snake. Here’s a breakdown of common DIY solutions:
- Boiling Water: Pour a kettle of boiling water down the drain to melt grease and loosen debris.
- Baking Soda and Vinegar: Pour one cup of baking soda followed by one cup of vinegar down the drain, let it fizz for 15-20 minutes, then flush with boiling water to help break down the clog.
- Drain Snake: If the blockage is deeper in the pipes, a drain snake can help physically remove the clog by reaching into the pipe.
- Plunger: For clogs near the sink, a plunger can sometimes dislodge the blockage by creating suction.
- Salt and Baking Soda: Mix ½ cup of salt and ½ cup of baking soda, pour it down the drain, and follow with boiling water to help break down blockages.
- Chemical Drain Unblocker: If all else fails, you can use a chemical drain unblocker like Mr Muscle. Be sure to follow the instructions carefully and take necessary precautions, such as wearing gloves and ensuring proper ventilation.
While these methods can work for minor blockages, if the clog persists or the drain is still slow, it may be time to call a Sydney professional plumber. Persistent blockages often indicate more serious issues that require expert attention.

To prevent future blockages, avoid pouring grease and oil down the drain, use a sink strainer to catch food scraps, and run hot water down the sink regularly to break down grease buildup.
