You can typically unclog a kitchen sink by using hot water, a plunger, or by cleaning the P-trap under the sink. Work through these methods in order of effort to clear the blockage safely.
Most kitchen sink clogs can be cleared using a sequence of DIY methods. Start with the least invasive options: pouring hot water (or boiling water for metal pipes) to melt grease, followed by a baking soda and vinegar mixture to break up organic buildup. If the sink remains clogged, use a flat-bottomed sink plunger to create suction. For stubborn blockages, remove and clean the P-trap—the U-shaped pipe under the sink—as this is where most debris accumulates. If the clog persists, use a drain snake to reach deeper into the pipes. Always bail out standing water before starting and ensure you have a bucket ready when opening the P-trap.
Answer details
Use Hot Water First
Start by pouring hot water or a kettle of boiling water (if pipes are metal) down the drain to melt grease. For PVC pipes, use very hot tap water to avoid warping joints.
Try Baking Soda and Vinegar
Pour 1 cup of baking soda followed by 1 cup of vinegar into the drain. Cover the opening for 15–30 minutes to allow the fizzing reaction to break up organic matter, then flush with hot water.
Plunge the Drain
Use a flat-bottomed sink plunger. If you have a double sink, plug the other drain with a wet rag to ensure a tight seal and effective suction. Pump vigorously for 15–20 seconds.
Clean the P-Trap
Place a bucket under the U-shaped P-trap, unscrew the slip nuts, and remove the trap to manually clear out accumulated grease and food debris. Reassemble and check for leaks.
