    Have you ever had a clogged drain? The most embarrassing clog of my life occurred the year we hosted Thanksgiving dinner for my entire family. Somewhere between the liquid turkey fat and potato peels my kitchen drain gave up and began regurgitating murky brown water mixed with bits of food from the disposal.

    Watching me frantically plunge the kitchen sink was NOT the most appetizing pre-dinner activity.

    Commercial Drain Cleaners

    What’s even worse than an embarrassing clog? Being forced to use dangerous chemicals to unstop backed up sinks and clean slow flowing drains.

    Flush the toxic chemicals and learn the easy way to naturally clean a clogged drain and speed up slow flowing pipes.

    (Hint:  You probably have the supplies in your home and it’s not baking soda and vinegar!)

    What Causes Disgusting Drain Clogs?

    Have you ever tried to stop a leaking air mattress from deflating? It’s impossible to stop the air loss until you find the hole.

    The same principle applies when cleaning a clogged drain… you cannot clean and declog if you don’t know the cause of the problem.

    Want to naturally unclog a sink or clean a slow moving drain? Learn why you should not use baking soda and vinegar to clean your drains and what green solutions really work!

    Most household drain clogs are caused by four substances.

    Kitchen Sink Clog Causes

    1. Fat, Oil and Grease (or FOG): Fatty substances are the number one cause of kitchen sink clogs and slow draining sinks. – they go down the drain easily in a liquid state (think hot grease in a pan or dissolved fat in warm dishwater) BUT as they move through your pipes the fat cools. This solid fat coats the pipes’ insides getting thicker and thicker until you have a slow drain or complete blockage.
    2. Food Particles: Large food particles or vegetable peels that  become trapped in the curved pipe beneath the sink (also known as the p-trap)  are another common cause of kitchen drain clogs.

    Bathroom Sink Clog Causes

    1. Hair: Hair is the most common cause of bathroom drain clog. The hair easily goes down the drain with water then accumulates inside the pipe building up until the line is blocked. These clogs usually occur right below the drain.
    2. Soap Scum: Greasy soap residue and particles can also coat the interior of pipes and cause a blockage. In some cases the soap buildup can become so bad it can actually corrode the pipes.

    The Right Tool (or Trick) for the Clog

    After you make an educated guess about the cause of the clog, four tools and tricks will help you naturally unclog your drain and remove debris without calling a plumber.

    1. A Plunger

    • Works On: Food particles or objects stuck in the p-trap (the curved pipe) beneath your sink. Try this on completely clogged or slow-draining drains.
    • How to Use: Clear the surrounding area in case of water splashes. Fill the sink halfway with warm water then give your sink a good plunging using a rubber plunger. Rinse drain with hot water.
    • Why This Works: The plunger dislodges stuck food particles and allows them to pass down through the drain pipe. The water rinse washes them down the drain.

    2. Long Wire Hook

    • Works On: Hair or small objects stuck in bathroom drains. Try this on completely clogged or slow-draining bathroom drains.
    • How to Use: Bend the end of a long piece of wire into a small hook using pliers (a coat hanger works great) or get a drain cleaning tool. Carefully remove the drain cover, remove any visible debris, then insert the hook. (You’ll want to wear gloves, it is gross.) Pull the hook back up and remove any debris (this will be a bunch of decomposing hair and gunk). Use the hook a few times in the drain to make sure you entirely clear the debris. Dispose of the debris in the garbage.
    • Why This Works: The hook removes the hair and debris that was blocking the drain, leaving it clean and free-flowing.

    3. Liquid Dish Detergent and Hot Water

    • Works On: Grease clogs or fat narrowed pipes. Try this on slow-draining kitchen drains.
    • How to Use: Heat 2 liters (a large pot of water) to a boil then stir in a few tablespoons of natural hand washing dish detergent or Sal’s Suds. Slowly pour the nearly boiling water down the slow running drain and then flush with hot tap water. This can take several pans of detergent and hot water.
    • Why This Works: The hot water melts some of the grease narrowing the pipes, and the dish detergent helps to dissolve the fat. This combination of cleaners removes the gunky buildup and allows drain pipes to run more freely.

    4. Salt and Hot Water

    • Works On: Grease or soap clogs and fat or soap narrowed pipes. Try this on slow-draining kitchen and bathroom drains.
    • How to Use: Pour one-half cup of salt down the slow-moving drain. Heat 2 liters of water until it is nearly boiling then slowly pour down the drain and flush with hot tap water. It may take several rounds of salt and hot water. You can use any type of salt (table salt, sea salt, or kosher salt).
    • Why This Works: The hot water melts some of the grease that is narrowing the pipes. The salt has an abrasive texture that acts as a natural scouring agent, forcing more greasy build up out. This combination of cleaners removes the gunky buildup and allows drain pipes to run more freely.

    5. Biological Enzyme Cleaner

    • Works On: Organic based clogs like grease, hair, and soap. Try this on slow-draining kitchen and bathroom drains and homes with septic systems. Enzyme cleaners can also be used regularly to keep drains free of organic material and odors.
    • How to Use: Follow package directions. Best used overnight when drains are not being used.
    • Why This Works: Biological cleaners such as Earth Enzymes Drain Opener or Biokleen Drain Gel contain enzymes and/or bacteria that eat through the organic material in the clog to clear the drain. These cleaners can be used in homes with septic systems because they don’t kill beneficial bacteria. (Green Gobbler Drain Clog Remover is another popular solution, it uses monosodium sulfate, a non-toxic acid,  to remove drain gunk.)

    How to Naturally Clean a Clogged Drain-5

    How to Prevent Drain Clogs From Coming Back

    After you declog a drain, follow these five guidelines to prevent the problem from reoccurring:

    1 – Never put FOG (Fats, Oil or Grease) down a drain or garbage disposal. Any substance high in fat (think bacon grease, coconut oil, butter, peanut butter, and other high fat food) should be cooled and then disposed of in the trash or wiped into the trash before washing.

    2 – Don’t use hot tap water to melt fats so they can be rinsed down the drain. They will cool and clog your pipes!

    3 – Dispose of food waste and vegetable peels in the trash!  Do not put onion peels, potato peels, banana peels, egg shells, rice, pasta, celery, and so on down the garbage disposal or sink drain. Check your manufacturer’s guide for details.

    4 – Install a hair filter in bathroom drains. Never flush hair down the drain when cleaning, wipe loose strands up and throw them away in the trash.

    5 – Flush kitchen drains once a month with salt and hot water.  This combination prevents greasy build-up and keeps drains running at full capacity.

        Yes, the salt and hot water can also be used in a bathroom drain, however you might have more luck with a acid based cleaner such as white vinegar which can help break down limescale and soap residue. Unfortunately, bathroom drains are usually slow because of hair clogs so physical removal is the best solution.

          Dish soap, boiling water and plunger did trick on kitchen sink Unfortunately I tried draino one day, baking soda & vinegar next then had friend use 30 foot snake. Plunged a lot of gunk out but still clogged. Today did dish soap and boiling water before having to call plumber and YAY IT WORKED. So glad I saw this article today. Thanks!

        White vinegar is a great deodorizer. You also might need to take apart the drain cover and give it a good scrub. I’ve also heard of using vegetagle oil to help with drains that have standing water by design. This article has a great explanation.

      Totally worked! Thank You! Kitchen sink was barely draining. Very old house, no garbage grinder, I’m careful about wiping plates and pans and not rinsing any grease or scraps down the sink, but something happened. I used Dawn and lot of hot water for several nights, helped a little. Next used Dawn plus hot water and then kosher salt and hot water for two nights plus a short wire. Suddenly the sink cleared. Now it drains really fast, I’ve been here 22 years and this is the best it’s been! What a relief. I’ll do salt plus hot water once a month now as maintenance. I’m telling my friends about this too. Thanks again!

I meant to get some drano before all of this went down, but didn’t get to it. As the days have gone by sink drain has been getting slower and slower to drain. I tried your salt and boiling water method and I finally got it to drain, so thank you so much! I had to stuff the salt down with a chopstick before and after I poured the hot water down. Once the salt got down in there, all the water finally went down! Thank you again 🙂

        I would clean the drain with soap and hot water or vinegar and use a fruit fly trap (vinegar in a jar with a bit of dish soap) to attract and kill the flies. An enzyme drain cleaner may help too.

      Wow!!! I have a special needs adult son that loves to clean up and wash dishes. I suspected he didn’t dispose of the grease after we fried some chicken among other things he washed down the drain. Sure enough a week later now we had a clog. I used the salt/boiling water along with some Dawn. It took a couple of applications (I have no patience to wait..) but IT WORKED!!! Thank you. I have now subscribed because of this AND the fact that you experiment and post what doesn’t work as well as what does work with various alternatives.

      It was a nightmare for me. Previously we had to prematurely leave a rental apartment, which also had a clogged sink causing us infinite misery. I had tried every chemical out there, nothing worked. Since then we have shifted to a different rental apartment (the sink was not the main reason), and to my utter horror, soon the sink started to become slow draining, and finally got totally blocked. It was like “Return of the Clogged Sink”! I heard that professionals often charge 100s of Euros, and throw all sorts of attitude etc. I saw bad reviews on Google.

      But then I found your post. With nothing to lose I poured in some amount of liquid dish washing soap on the accumulated water in a fully blocked sink. A while later I witnessed the water to have drained. It felt like a miracle. I followed with several rounds of dish washing liquid and boiling hot water from kettle. It brought the situation from completely blocked to very slowly draining. Then I followed through with the plunger. It regurgitated lots of particles and gunk, but now it is almost draining okay, with a little bit of accumulation only!

      The thing is I am going through several crises in life right now. I cannot explain everything. But on top of it all a clogged sink was too much, and even if I had to call professionals, it would have been a nightmare for me for various reasons (money being one for sure). So you really ended up helping me big time. I thank you profusely. And may you and your family live blessed.

      Hi Bren, I tried all the tricks, and nothing worked. I ended up getting a plumber who couldn’t unplug it. He said it was a gelatinous glob that the snake couldn’t break loose. I hired a steam truck to clean it, finally it broke free. It was something I never imagined it could be. The powdered soap packets that I used in my dishwasher was the culprit. The soap never dissolved completely, and gelled in the pipe. Even my plumber recommended the baking soda and vinegar. If you have powder packets for the dishwasher, dissolve it in hot water before using it. The liquid ones are fine. Just wanted to share my experience with your readers. Thanks

        Thanks for sharing, Lyn. Vinegar or hot vinegar would help the most with the hardened soap since vinegar breaks down soap (vinegar has a pH of 3, soap has a pH of 7 or 8) due to the acid/base reaction. The baking soda would lessen the power of the vinegar (vinegar has a pH of 3, baking soda has a pH of 8-9) to attack the soap scum due to the same acid/base reaction so I’m not sure why a plumber would recommend it for soap clogs. I’d prefer the vinegar to be full strength when reaching the soap clog.

      My kitchen sink has been slow draining and clogged since I’ve moved in here about 4 months ago. I’ve tried all kinds of commercial drain openers and decided to get a snake. Nothing worked. I checked the web and found the salt and warm water idea. Had nothing to lose, so I tried it. And wow, I can now use my sink without having to wait for it to drain. It took about 15 – 20 minutes of waiting, but then, poof, water went down, and has been draining just fine since. This is the best it has ever been. Will pour some salt and warm water down it monthly to keep it flowing

I moved in 3 years ago, before that my parents had lived here for 25 years ( they had problems with the drain ), prior to that my dads aunt and uncle had lived here since they built the house in 41. The kitchen drain goes into the basement in a 2″ steel pipe that runs about 35 feet till it hits the 6″ pipe that runs out to the septic system. The steel pipe is original.

      A safety note for those plunging a bathroom sink that has an overflow drain at the back. The water may spray back out through this drain…plunge carefully rather than vigorously and be prepared to pull out quickly.

      I love all your suggestions for slow running drains. However, an you help me with a kitchen double sink drain that is running fine but I can’t stand the moldy smell anymore. After w moved here the drain completely stopped up and called the plumber and he worked for hours getting the grease out. I do not put grease down at all. When he used the plungeer on either side he plugged up the other side with a rag and the filthy water backed up into my diswasher that is attached to the drain.

      My question is I think I have mold build up in the drain (I changed the sink stoppers and that did no good) and so far only used grease relief, a natural mold cleaner (M2 ) and hot water with dish detergent. Am thinking of using vinegar and baking soda to kill the mold but do you think it is safe as the dishwasher detergent contains bleach and this water drains into the sink drain. Is there a chance of creating a problem if I use vinegar in the drain? How much water wouyld I have to use to wsh it away before using the vinegar?

      Do you have any other ideas to c lean out a smelly musty drain in the kitchen. Also would I have to put the vinegar and baking soda in both sides – I imagine I would or the pipe from the other part of the sink to the main drain would not get any benefit I guess., so how much do I put where? Tjhanks for any suggestions as I am 80 years old and very allergic to mold and need help. Did not want to call the plumber over this as can’t afford it especially just fora smelly drain – plus the last time he was here it took me days to really get things cleaned up. I am not feeling well enough to do plumber cleanup.
      Thank you for any help and suggestion.

        Add on to above post: There is no smell in my dishwasher at all so there is no problem with that — only the sink drain. However I do wish the diswasher had a backflow valve of some sort so I never experience what happened from the plumber with the back up when he did his plunging. Gross!

      I have never clogged my kitchen sink but have a pamphlet from akaction.org with the vinegar solution so id just told a friend to try it. Then decided to Google it and found your other post which i shared with her. Something i do not understand is why the vinegar did not have impact on butter in your experiment. I use it exclusively to clean my home. Sometimes i have to leave it on a spot for awhile, but it has never failed to cut through the filth to allow wiping it clean. It cuts through grease and i thought butt was similar so i was very surprised. Not really surprised about not unclogging unless used with hot water.

      However, I am extremely surprised about the risk of damage if you pour hot liquid down drain so I Googled that, too. what I found leads me to believe the water need not be boiling to cause damage. I think you might be incorrect about this.

      http://www.balkandraincleaning.com/sewer-drain-pipe-cleaning-facts-information-solutions/

      . “Most chemical-based cleaners generate heat inside the pipe; PVC may not withstand the heat and it will melt, or harm the integrity of the pipe joints. On the other hand, metal-based pipes such as galvanized steel and cast iron can corrode. So be careful which product you use”

      It is not clear to me that the water must be boiling in order to damage pipes, but I found both of your posts informative and helpful. For my bathroom drains I have used wire method. Disgusting with or without gloves lol. I am going to check out your enzyme links

      Bren, your research, experiment and informed opinions / facts are most impressive and priceless. I’m a widower, long time English instructor in a small, non-English, college village. So, I have only one option, to unclog narrow plastic drain in 40-year old bathroom sink — rock salt and a one-litre electric kettle. I could only force down a tablespoon of rock salt with a wooden chopstick. Hardly noticeable effect on the initial application. However, with each try, I saw improvements. I expect complete cleanout before too long.

      On my 4th try now, with managing to stuff almost 4 tablespoons of salt into drain. Thank you so much for your outstanding report / article / blog. You are an angel !

      Again Bren, many thanks, from South Korea.

      Have a positive, productive day, educating and saving humanity, as Donald would say, making America [ and the whole world ] great again, one clogged drain at a time.

      Bren, thank you SO much for taking the time to research, and to write this post. I was thinking to myself that maybe baking soda would work to unclog our pitifully slow-draining bathroom sink. I Googled, glanced at several articles about using baking soda/vinegar, but then saw your article. I hadn’t heard of, and wouldn’t have THOUGHT of, using salt.

      I really didn’t have the time to take to do it just now, but thought “what the heck — I’ll just try a little salt real quick.” In under 10 minutes my sink, which would fill up completely in under 15 seconds and take well over 2 minutes to drain, is draining in under a minute!!! I am astounded!!! And SOOOO happy!!!

      I have long avoided synthetic chemical cleaners, pesticides, herbicides, fertilizers, and eat as much healthy, whole food as possible. That said, until this morning, I hadn’t found any ‘green’ solution that worked for clearing my horribly clogged bathroom sink.

      I will regularly be using this method from now on.

      Thanks again!!

      Will hot water and detergent work on a completely clogged kitchen drain? (Clogged from melted butter).

        January 23, 2017 at 9:25 am

        It should work if the drain is clogged with butter. (The hot water should melt the butter and the weight of the water helps the clog pass.) Since you have added Draino I would use hot water only, make sure to wear protective eyewear, and keep everything away from the sink in case it back ups when pouring down the hot water. You want to be VERY VERY careful around the Draino. Good luck!

      I had a professional plumber tell me that in the kitchen sink, ALWAYS run water for close to a minute before turning on disposer. Then turn off disposer when particles are gone and LET THE WATER RUN AGAIN. He said people don’t push the debris all the way through the pipe with the water. The particles get stuck and build up. That’s what causes sink back-up and odor.
      Tonight I tried using coarse salt and hot water. It worked great for me in a bathroom tub/shower unit and sink.

      The same recommendation regarding boiling water is on crunch betty website and i am sending the same response that I sent to crunch betty….which, by the way, never responded.

      PLEASE PLEASE check to see about poring boiling or very hot water down a drain. Most drain piping currently being used is PLASTIC…PVC…ABS which cannot tolerate high temp water.
      Look at the max temp rating for PVC pipe ABS type…I think you will find max temp to be about 150-160 degrees. ABS is designed for high temps but not boiling water.

      I hope you will read this and respond. I am offering this advice to help protect drainage systems.

      tried your method today, it was a combination of salt and then hot water with dish detergent. I repeated it three times in a row, it unclogged the drain the second time, so I just poured hot water with little detergent the third time for good measure :).

I waited 5 min & then flushed the pipes with lots of hot tap water. Did this 2 weeks ago & the water drains perfectly.

        We successfully used this too, but the key is to plug the drain…its kinds like using a plunger from inside the pipe, its not the solution that results from the chemical reaction that does anything, its the pressure of the reaction its self, and you want to block that coming up and force it down presumable through the clog, then flush with boiling water to get anything that is left.

Any substance high in fat (think bacon grease, coconut oil, butter, peanut butter, and other high fat food) should be cooled and then disposed of in the trash or wiped into the trash before washing. Don’t use hot tap water to melt fats and rinse them down the drain, they will cool and clog the pipes!”

      Don’t use the salt too much, it can cause the pipes in your drain to corrode. Also if you are on a septic system too much salt can eat away at the tank. So if you use salt to soften your water, and you’re unclogging your drain with salt all the time it could increase the change of issues.

        Actually drain cleaner and antibacterial cleaning products are much more dangerous to a septic system than salt or salt softened water. You can read more about it here. Corrosion usually occurs when metal is standing in salt water. This method rinse the salt away quite quickly. I feel safer using salt than store bought drain cleaners.

      I first tried the mechanical method (inserting something down the pipe) to clear my excruciatingly slow-draining bathroom sink pipe, and it did nothing. Finally I did the baking soda & vinegar thing. Just before going to bed I poured baking soda down, followed by vinegar, and left it overnight. Worked like a charm.

      My theory is this: the bubbling action dislodged or broke up whatever was built up, so that it simply was carried away when I turned the water on the next day. The only alternative to dislodging would be dissolving, which in the case of hair, etc., would require caustic chemicals, which of course we want to avoid entirely.

          I just tried your way Bren hat water & dish soap. Admittedly, very skeptical. I was shocked! Why wait over night when this technique works almost instantaneously? Thank you!

        Personally I use a plunger with co2 cartridges, it works like an air gun with no physical effort. You flip the head for drains vs toilets. Most people use the wrong plunger for the job.
