Coke. Coke is a lesser-known fix you can find in your refrigerator. Pour a 2-liter bottle of cola — Pepsi, Coke, or generic brand substitutes — down the clogged drain. Coke is actually quite caustic and effective at clearing away buildup in your drains, but it's far milder than commercial drain cleaners.
Allow a two-liter bottle of soda to come to room temperature. Pour the entire bottle down the clogged drain. Allow it to sit in the drain for at least an hour or two (or even up to 24 hours for stubborn clogs). Flush drain with boiling water.
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.
Baking Soda and Vinegar
This combination of baking soda (sodium bicarbonate) and vinegar may be one of the best homemade drain cleaners around. First, if you want to unclog a tub or sink drain, pull out the stopper so that you can access the drain. Then, slowly pour a pot of boiling water down the drain.
Combining baking soda and vinegar is a natural way to dissolve hair clogs, without resorting to harsh chemicals. Pour a cup of baking soda down the clogged drain first, and then after a few minutes add a cup of vinegar.
Although you can use 1/5 to 3/4 of a cup of bleach to clean and deodorize drains, followed by a good flushing of hot water, it will not clear a clog. Bleach is amazing at sanitizing and killing germs, but it won't eat through hair and soap scum that's trapped in the pipes and causing a clog.
Coke is acid, and the acid joins up with the carbonate in baking soda to form hydrogen carbonate. Hydrogen carbonate then breaks up to become carbon dioxide and water. The carbon dioxide then bubbles off as a gas.
Baking soda and salt work similarly to baking soda and vinegar. Again, combine a 1/2 cup of baking soda and 1/2 cup of salt. Let this sit in the drain for at least 30 minutes or as long as overnight and then pour hot water down the drain. Repeat this process if necessary.
Hydrogen peroxide dissolves organic matter to loosen and flush away debris such as skin cells. It also disinfects the drain as it works by reducing germs inside your pipes and making your sinks smell fresh and clean.
To get it really clean, use an anti-bacterial spray cleaner, a brief soak in bleach solution, rubbing alcohol or a similar disinfectant to disinfect it. This will help slow down the stink and gunk build up a little before you need to clean out the drain next time, hopefully giving you a more pleasant experience.
In case your drain is susceptible to frequent clogs, using hydrogen peroxide may prevent the clogs from recurring. You can do this by pouring hydrogen peroxide (one cup) down the drainage every 14 days. Allow it to settle for an hour and then pour several cups of hot water down the drainage.
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.
Just like carbon dioxide bubbles in a carbonated drink, the carbon dioxide (that formed as the carbonic acid decomposed) rises to the top of the mixture. This creates the bubbles and foam you see when you mix baking soda and vinegar.
Another toilet cleaning method is mixing 1 part of Coke, 1 part of lemon juice and 2 parts of borax. Apply the mixture to your bowl, let it sit for about an hour and then scrub the stains off.
When the salt gets is added to the coke, it changes the balance of the its chemistry and forces the release of carbon dioxide bubbles. This occurs because the salt overpowers the carbon dioxide and replaces it in the soda. The carbon dioxide then has nowhere else to go but out, which causes the explosive sensation.
Bleach is a “basic” chemical and hair is “acidic”. The neutralization reaction between an acid and a base produces a salt and water. Bleach can dissolve any fiber that has acidic properties. Next time you have a bathroom sink, shower, or bathtub draining slow try pouring a cup of liquid bleach into the drain.
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.
Try Using Boiling Water to Fix a Clogged Sink
If you have metal pipes, you can try to loosen the clog with hot water—very hot. Pouring a pot of boiling water directly down the drain into the trap may dissolve the clog, especially if it consists of soap scum or grease.
Hydrochloric acid, also known as muriatic acid, is the most common acid used by plumbers to unclog drains. Although this component can be found even in your own stomach, as part of the digestive acids, its pure concentrated form can only be purchased from certain stores if you carry a plumber's license.
Baking soda, vinegar and Dawn dish soap along with boiling water can safely unclog a drain. Baking soda, vinegar and Dawn dish soap along with boiling water can safely unclog a drain.
Water & Salt
Pour a few cups of boiling water down your drain, then follow it with a two tablespoons of Epsom salt. Let it sit for a minute, and follow with another few cups of boiling water. The water and salt mixture should help break up the clog.
