Just pour a small amount of baking soda down the drain, followed by a cup of white vinegar. As the baking soda and vinegar start to work, you will hear a fizzing noise. Leave for a few minutes, and use hot water to wash the mixture down the drain. Another method is to use soda crystals to unblock the sink.
Use baking soda and salt. Mix about a cup of baking soda with half a cup of salt, and pour this mixture down the drain. Let the mixture sit for several hours, then flush with boiling water. You can repeat this process if it doesn't clear the clog.
Use a Plunger
This handy tool works using water pressure, so with a double sink, you'll need to cover the unclogged side with a rag or a basket strainer to seal it. Fill the clogged sink with 4 to 5 inches of water (don't use chemical cleaners here), and plunge the drain for 20 to 30 seconds.
If you have a double-bowl kitchen sink, stuff a wet rag into the drain opening that isn't clogged (this will help with suction). If your sink doesn't have a garbage disposal, use Drano® Kitchen Granules Clog Remover. It creates heat inside your drain to melt and dislodge greasy clogs.
You can use Drano® Clog Removers to unclog a kitchen sink, bathroom sink, shower or clogged bathtub, but DO NOT use them in toilets. For clogged or slow-running drains, apply the product and let it work 15 minutes, then flush with hot water. For tough problems, allow 30 minutes before flushing.
Over time, grease, food particles, and other debris can collect in the P-trap and cause a clog. If this happens, it can prevent water from flowing through the drains and lead to a double kitchen sink backing up to the other side. If you're comfortable doing so, remove the P-trap and look inside it for any blockages.
If your snake isn't unclogging your drains, it could be because the thumbscrew is loose, the clog is too severe, or the auger is dirty. Or maybe you just need a refresher on how to use a drain snake. A drain auger (snake) is a simple, inexpensive necessity for every homeowner.
Slow drains may not always be due to clogs.
Plumbing vents, soap buildup, and garbage disposal malfunctions are among the most common culprits. Understanding these different causes can help you better determine the best course of action to address the issue with your kitchen sink.
When you are using a baking soda and vinegar solution to clean out your drain, you are actually causing the rubber and plastic that are used for the drain's pipes to be eaten away by the mixture. Over time, this rubber and plastic will break down, causing the drain to become even more blocked.
Pour one cup of fresh baking soda down the drain, followed by one cup of white vinegar. Place a rubber stopper or other sink hole cover over the drain opening. Wait 15 minutes to allow the vinegar and baking soda to unclog your drain, Then take out the drain cover and run hot tap water down the drain to clear the clog.
You may be surprised to learn that pouring soda down the drain does work for some clogs. To be specific, you need a dark-colored cola (such as Coca-Cola or Pepsi). This type of carbonated beverage usually contains a good amount of phosphoric acid, which given enough time, can eat away at some types of clogs.
Salt & hot water
While hot water can help loosen up debris, coarse salt actually scours the inside of your pipes, removing more material than hot water alone. After removing standing water from the sink, pour about half a cup of table salt down the drain before you pour in the hot water.
If you suspect a grease clog, a mixture of very hot water and vinegar can also help melt and remove the grease that's blocking the pipes.
Using Hydrogen Peroxide on a Clogged Drain
You can try pouring some down the drain directly, but for more effective drain clearing, follow these steps: Sprinkle about one cup of baking soda down the clogged drain and wait for 10 minutes. Pour one cup of hydrogen peroxide down the drain and wait for the foaming to stop.
It is Extremely Corrosive For Your Drains
When your pipes are clogged, Drano will sit on top of the clog, continually reacting and generating heat until the clog dissolves. This can put a great deal of stress on your drains as the heat can cause PVC pipes to soften and even break or collapse.
Using a snake is also more invasive and time-consuming than using a chemical cleaner is, and can often become a dirty job. When it comes to getting at and removing major clogs or clogs that are deep down in your pipes, however, a plumber's snake is your best bet.
When Drano won't go down the drain, grab a plunger instead. Many people think that these are only good for toilets. However, they can create suction that can dislodge your clog. Make sure that you get a plunger that can seal all the way around your drain.
The best way to clear that clog is by pouring Drano® Max Gel Clog Remover straight over the drain (even if there's standing water). It works by dissolving the remaining hair and gunk—and boom! It works within minutes, and keeps your drain flowing smoothly!
