There are homemade methods capable of solving the problem safely and easily. To find out how you can properly unclog the kitchen sink yourself, take a look at the tips we’ve separated below:

How to unclog a sink: 12 tried and true methods

Fat and food debris can accumulate in the pipes and clog your sink. Depending on the severity and reason for the clog, you need to use a specific method. See below for 12 effective home methods to unclog your sink yourself with no hassle.

1. With detergent


Often, the kitchen sink clogs because of grease in the plumbing. If this is the case, you can solve the problem by just using detergent and hot water. First, remove any accumulated water from the sink. Then boil 5 liters of water and mix with detergent. Finally, pour the liquid down the drain.

2. With soap powder


Like the previous method, this one is for cases where there is excess fat in the pipes. You will only need a little washing powder and 5 liters of hot water. Let’s go step by step:

First, you need to empty all the water in the sink. Then cover the drain with washing powder so you can’t see anything but the soap. Then pour hot water on top, about a liter. Now just turn on the faucet and observe the result.

3. With wire


If the problem is some solid residue, like hair or wires inside the pipe, you can use a wire to unclog it. Take 3 wires of the same size and braid them. Curve the end of each of them, forming three hooks. Tuck the wire into the drain as far as you can and twist it, trying to pull out the dirt.

4. With rubber plunger


Easy, fast and everyone knows!

To use a rubber plunger, you need to fill the sink with enough water to cover more than half of the rubber part of the object. Place it over the drain and make firm, slow movements up and down. Then remove the plunger and see if the water has gone down or not. If the sink is still clogged, repeat the operation.

5. Cooking salt


This is a product that everyone has at home and that can help you unclog the sink.

Put 1 cup of table salt down the drain and pour boiling water on top. While the water drains, close the drain with a cloth, applying pressure. Remember to wear gloves so you don’t burn your hand.

6. With bicarbonate and vinegar


Vinegar and bicarbonate are the darlings when cleaning the house , and can also be used to unclog the sink. For this you will need:

  • 1 cup of baking soda;
  • 1/2 cup of vinegar;
  • 4 cups of hot water;

Before starting the process, it is necessary to empty the sink. Place the baking soda on top of the drain, then pour in the vinegar. The two will react and bubble. When this process is finished, pour the hot water on top. Now just wait about 15 minutes and see if the clog is resolved.

7. Chemical plunger


If none of the above methods have worked, there are effective chemical plungers on the market. But, before using them, be sure to make use of protective equipment, as these products are harmful to human health.

Follow the instructions on the package correctly and wait the indicated time. Before using the sink normally, let plenty of water run to wash away the remains of the product.

8. With caustic soda


Caustic soda is a toxic product that unclogs sinks and pipes easily. However, it is highly corrosive and, if used frequently, can damage pipes. Therefore, this method is only indicated for more critical clogs.

Pour 1 cup of the product down the sink drain, then pour a kettle of hot water over it. Let it rest all night. Then let a lot of water run down the drain to ensure that there is no leftover of the product. Remember to always wear protective equipment (glove, goggles and boots) and correctly follow the manufacturer’s instructions.

9. With enzyme products


If you don’t want to risk using toxic products in your kitchen, don’t worry! There are products that use bacteria and enzymes in their composition, which do the work of breaking down organic matter in the sink and pipes.

Before use, carefully read the instructions for use and remember to wear safety equipment such as gloves, mask and goggles. Apply the product in the sink and let it act for the time indicated on the package. Then pour hot water on top.

10. Clean the siphon


Sometimes the siphon accumulates food residues that block the passage of water and cause clogging. For those who don’t know, the siphon is the pipe that is at the outlet of the sink, in the shape of an “S”.

Before starting this method, place a bucket under the sink to prevent water from running all over the kitchen. Then unscrew the siphon and clean it with a long sponge, water and detergent. Then just put it back in place.

11. With unclogging probe


Have you tried all the previous methods and none have worked? Then you will need to use an unclogging probe.

This type of material is sold in building supply stores. To use, just insert the cable into the drain, as far as you can, and turn the knob. This will make the waste come off the pipes and solve the problem. That simple!

12. With hose


Sometimes it’s the wall pipe itself that is clogged, so you’ll need to use a method that’s a little more laborious, but still easy and effective. To do this, separate the following materials:

  • a hose connected to a working faucet;
  • an old rag;
  • a screwdriver;

Wrap the cloth around the hose, a hand or two from the end. Then remove the siphon (at the end that is attached to the wall). Stick the hose into the pipe as far as you can. With the help of a screwdriver, push the cloth into the pipe, without removing the hose, so that it forms a kind of barrier at the edge of the pipe. Connect the hose: the water will pressurize inside the pipe and unclog it. Finally, just disconnect the hose and replace the siphon.

Knowing how to unclog a sink is important, but even more useful is knowing how to prevent the problem. Keep an eye out for tips to prevent clogs:

How to prevent clogs


The main reason for clogged kitchen sinks is the accumulation of grease and food leftovers. To avoid the problem:

  • Avoid discarding food in the sink;
  • Use a strainer in the sink drain to prevent solid waste from falling into the pipe;
  • Do not pour cooking oils down the sink. Put them in PET bottles and take them to the appropriate collection center;
  • At least once a month clean the pipes, pouring a few liters of hot water down the drain.
