Awaken your inner Monica Geller! Note these 5 super easy and useful ways to unclog a double kitchen sink.

1. Reset Garbage Disposal

A clogged kitchen sink ( stainless steel or iron sink ) can result due to various reasons. A technical failure of the garbage disposal system can be one of them. A garbage disposal grinds the waste material into small bits for easy drain flow, but items like coffee beans and eggshells can jam its functioning. Maybe it’s time to reset and restart your garbage disposal.

Firstly, locate the garbage disposal underneath the kitchen sink. Check if it’s overheated or at a standstill. You will see a reset button on it. Press the reset button two-three times to see if it restarts the draining smoothly. Switch off the garbage disposal and wait for some time. Restart it again. This should clear the clog. This is the first thing you should try for unclogging sinks.

2. Use A Plunger

If the reset switch method becomes unsuccessful, use a plunger. A plunger is a plumbing tool used to clear blockages by harnessing pressure. The plunger is a trial-and-error technique as it requires continuous attempts.

Firstly, remove excess water floating in the sink. Keep the minimum water level till the plunger cup. Now put the plunger cup over the clogged sink directly over the drain. Hold firmly and press to build pressure. Make sure the plunger cup is air-sealed.

Now move the plunger up and down at six equal intervals whilst maintaining a tight grip. Now loosen the cup. The pressure forces the clog to break by draining residue down the plumbing system. Still, if water doesn’t drain down, repeat this method from the start. Once successful, pour boiling hot water into the sink drain to remove accumulated grease or oil.

3. Baking Soda and Vinegar

Home science cleansing remedies are very underrated but highly effective. Baking soda and Vinegar are powerful anti-clog agents that are easily available in homes and markets. The mixture of these ingredients works like a charm and gives instant results. Let’s learn their use. Take about one-third cup of baking soda in a glass/bowl.

Take an equal quantity of Vinegar and pour it over the baking soda. This will create an effervescence reaction. Without wasting a single second, pour this mixture down the drain. Allow it to sit for 30 mins- 1 hour. If possible, do this before sleeping and leave this mixture overnight for better results.

Baking soda and Vinegar break down stubborn grease, dirt particles, and material build-up. After the long wait, run hot boiling water in the drain to wash off all remnants and clear the area. Your drain will start functioning again. You need to try this method as the results are spell bounding.

4. Salt And Baking Soda

You will be astonished at how these simple kitchen ingredients can create magic for a clogged double kitchen drain. Salt and baking soda are readily available in your kitchen drawer. Time to employ it elsewhere than cooking. In a bowl, take ½ cup of salt and 1 cup of baking soda. Mix it well. Remove any standing water from the sink.

Now, pour down the salt and baking soda mixture into the drain. Be patient and let it do its job for at least an hour. Salt is an amazing declogging spur. It stimulates water flow by melting down grease and oil dirt. After an hour, just flush the drain with boiling water. This clears the drain completely by draining out all small residue particles.

Your kitchen sink and drain will restore perfectly for use. This is the most budget-friendly and quick resolution for clogged double kitchen sinks.

5. Snake the Drain

If every method has failed, it’s time to use the ultimate unfailing weapon- “The Plumber’s Snake.” A plumbing snake is a tool that can be used to break the clogs deep within the pipes and drain manually. It gives access to areas that are unreachable by other tools. It is mainly used when the plunger fails to unclog the sink.

Follow these steps for snaking the drain. Firstly, remove the drain cover/trap. Insert the snake wire into the drain towards the blockage. Now, dismantle and break the clogging culprits.

After you are done, retract the snake wire from the drain carefully (the clog should not fall back inside). Secure the drain trap. Finally, gush out the piping system with hot boiling water to remove any tiny leftover clogs. Voila! The sink and drain are in sync again.
