Baking Soda And Vinegar Drain Cleaner

Let’s start with one of the most used hacks. This approach is a natural alternative to using chemical drain cleaners. And the best part is baking soda and vinegar are common household items that you’ll  likely already have in the kitchen.

Items:

  • 1 cup Baking Soda
  • 1 cup Vinegar
  • Hot Water

Method:

  1. Remove any standing water with a cup.
  2. Pour the baking soda into the drain, followed by an equal amount of white or apple cider vinegar.
  3. The solution will soon start to bubble. The fizzing action is what helps remove the hair and grime so effectively.
  4. When the bubbling subsides, put the stopper in and wait about fifteen minutes to an hour.
  5. Run the hot water.
  6. If the clog is still but the water is draining just slowly, repeat the process one more time.

Boiling Water

Yea, we know it sounds way too good and easy to be true. It’s surprising how well this works. Not only that, but it is also cheap. Give it a go before trying anything else. Clogs appear thanks to hair, food, grease, and soap getting trapped. This is for metal pipes and not any PVC pipes.

Items:

  • Water
  • Kettle or Pot

Method: 

  1. Fill the kettle or pot with water and bring to a boil.
  2. While you’re waiting for the water to heat, remove as much standing water from the sink as you can, using a mug or small pot to bail out any water.
  3. Take the entire boiling water and pour it into the sink. Do this at three or four different stages. If it starts working, you will quickly find out.
  4. After that get the faucet running and see if the drain is working properly. If the water is still going down slow, you will need to do this at least a couple of more times.
  5. Always let the water cool before you go again. Remove any water left with a cup, container or jug.
  6. Repeat.
  7. If this isn’t working, move onto another method.

This method is not only easy, but it’s also the cheapest

Garbage Disposal

If the boiling water trick doesn’t work, it’s time to check out the disposal. The problem with this method works only with sinks that do have a garbage disposal. However, with sinks that do have it, it’s more often than not, the main reason for a clog. Run the disposal with some hot water.

Check the garbage disposal

If the disposal doesn’t turn on, it’s broken, if it is humming, it is probably jammed. If you cannot get it running, push the blades manually. Use an Allen wrench until there is barely any resistance. The garbage disposal should be turned off beforehand.

Overheated or dysfunctional disposals may not even turn on

Plunger

Well, now that we’ve established the disposal isn’t the problem, it’s time to turn to the bathroom plunger. There are different types of plumbers, so for working in sinks, showers, and tubs, we recommend using a cup or flat-bottomed plunger. Use a stopper or something to seal the other drain if the sink is a double type.

Items:

  • Plunger
  • Water
  • Stopper or Cloth

Method:

  1. Get the sink filled up with water. The water should be hot. Do this until it is halfway full. This should create a type of seal on the drain.
  2. Put the plunger on top of the drain. Start to pump. Make sure you are doing quick motions and many times.
  3. After that take away the plunger and wait. If the water isn’t draining then you need to repeat.

Baking Soda and Salt

Other than the baking salt and vinegar method, you can also try this one. If you don’t have any vinegar at hand, salt will do the job just as well. All components in this method create a pretty aggressive chemical reaction.

Items:

  • 1 cup Baking Soda
  • 1/2 cup Salt
  • Boiling Water

Method:

  1. Mix the baking soda and the salt together.
  2. Pour the mixture in the drain.
  3. Let it sit for at least fifteen minutes up to several hours.
  4. Flush out the mixture with boiling water.
  5. You can repeat this process again if needed.
  6. Another effective combination is baking soda and salt. Mix 1/2 cup of each and pour the mixture into the drain.

Plumbers Snake

A plumbers snake or sometimes also called an auger is a handy tool that can clear up stubborn clogs stuck further down the drainage system. If the clog is inside of the trap, this should do the job.

Items:

  • Plumber’s Snake
  • Warm Water

Method:

  1. Remove the drain topper if there is one.
  2. Extend the auger cable into the drain opening. When you feel it bump up against the clog, pull out about 12 inches more of the cable and tighten the setscrew on the auger canisters.
  3. Turn the crank handle of the snake clockwise. Apply moderate pressure on the cable. The cable end may get stuck on the clog or bends in the pipe. Do not push too rough.
  4. Turning the cable helps break up the clog or get the cable end past the bend.
  5. Extend more cable if required or until you feel you’ve worked through the clog.
  6. Pull the cable out of the pipe, pushing it back into the canister as you go. The cable may have a clog stuck to its end when it comes out of the drain.
  7. Repeat the process as needed. Do this is until the clog has cleared up.
  8. Flush with hot water from once the drain starts to flow.

P-Trap

If the clog has gone way beyond the drain, you’ll need to put in more elbow grease. But don’t worry it’s not impossible. It’s time to test the P-trap. A lot of waste gets stuck in there. It is the wiggly, elbow-shaped pipe that you see. Make sure to have goggles, towels, and gloves prepared as this is a messy method.

Items:

  • Bucket
  • Rag
  • Goggles
  • Gloves

Method:

  1. Put the bucket under the pipe. This will help catch anything that may fall.
  2. Now it’s time to unscrew the connectors. They hold together the curved pieces to the pipes.
  3. You will also find slip nuts on each end of the P-trap.
  4. After you opened it up, get rid of all the gunk.
  5. Put everything back together.
  6. Turn on the water. If it runs fine, then good job! The problem is gone.

This is called the P-trap because of it’s shape

Okay, so the clog is somewhere deeper. It’s time to try again. Go back down the the core of the pipe and follow these steps.

Items:

  • Bucket
  • Plumber’s Snake

Method:

  1. Unscrew the P-trap once again.
  2. After you have removed the p-trap, get the horizontal one that is connected to the system that is in the wall.
  3. With a hanger, or a plumber’s snake feel around and see if you can pull the blockage.
  4. Do this process over and over until everything is out.
  5. After the clog is done, put everything back together.
  6. Make sure to run hot water afterwards to flush the drain.

Coat Hanger

Not everybody has access to a plumber’s snake. That is why you can use a coat hanger, however it should be a wire one. Get some pliers and straighten it. However, keep in mind that it won’t go as far down as a professional term. But it is still worth a shot. Insert the hanger in the drain and make a pull and push motion.

If nothing else works, it may be time to call in the help of a professional. Find one online or ask around for a recommendation. Some home issues need more help than others, so don’t be afraid to search out someone who know the insides and outs of the plumbing systems.
