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.
When you mix baking soda and vinegar, the resulting chemical reaction produces carbon dioxide gas. This gas can build up inside your pipes, causing pressure to build and potentially leading to cracks or leaks in older pipes.
The bubbles that form in the reaction come from the carbon dioxide being created- and if you've ever mixed vinegar and baking soda together, you've noticed how quickly the bubbles form… so the carbonic acid doesn't last very long and is too weak to break down any materials in a clog such as hair or soap.
If the baking soda and vinegar method doesn't unclog the drain, use the salt and baking soda method next. This works best if you do it right before bedtime since the drain won't be used until morning.
Leave it in the drain for an hour or two or overnight, and then flush the drain with hot tap water. For larger drains, such as tubs and kitchen sinks, use about a quarter-cup of baking soda, a half-cup of water to move the powder down, and 2 cups of vinegar.
Clean the P-Trap
If a kitchen or bathroom sink drain still smells after removing trapped hair and using the baking soda and vinegar, there may be something caught in the p-trap that's causing the odor.
Baking soda and vinegar may unclog your drain better than Drano ever could. Start by getting rid of the standing water in your drain. If it will go down slowly, just wait until it's gone. If it isn't moving, use a cup or a spoon to get it out of there.
Baking soda powder will turn into a cement like mass and completely clog everything it settles in. I had a family member dump about three cups down the kitchen sink this summer and I ended up having to replace the trap, tailpiece and dishwasher drain inflow.
Vinegar. Vinegar is both safe and beneficial to pour down your drain. It acts as a natural cleaning solution and can remove blockages and harmful bacteria that cause foul odors.
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.
Pouring boiling water is quite risky as it might lead to a steam burn or scalding. Another thing to keep in mind is what type of material you are pouring in into. If you have a porcelain sink, it is likely to crack due to the heat. All in all, pouring boiling water down your drain will only cause issues down the road.
If your drain is clogged with hair, baking soda can dissolve hair in a drain. To try this safe and easy method at home - first, pour a cup of baking soda down the drain. Then pour a cup of vinegar (white vinegar) down. Allow the mixture to sit for several minutes.
Preventative Maintenance
Pouring bleach into the drain when the unit is not operating can leave residual bleach, which will damage the drain pan and line. Using vinegar for preventative maintenance throughout the year will keep your drain clean and clear and will not damage your line.
Clean the P-trap. If the water is still not draining correctly, there might be a blockage in the P-trap, aka the elbow-shaped pipe under your sink. Food, grease and other debris may be stuck in the pipe, causing your sink to drain slowly or not at all because the water hits a snag on its way down.
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.
Another option for dissolving hair in a drain is to use a mixture of baking soda and vinegar. This mixture will create a chemical reaction that will break down the hair. Mix equal parts baking soda and vinegar and pour it down the drain to use this method.
Use a Natural Cleaner
Begin by pouring up to a whole box of baking soda down the drain, depending on the severity of the slime. Then pour in the vinegar, up to half a bottle. You should hear or see the fizzing. Let it react for about five minutes, then slowly pour the boiling water down the drain.
Minerals refer to limescale or calcium buildup in drains, pipes, or plumbing fixtures. The buildup can occur in shower drains for example due to the sodium, magnesium, and other chemicals found in hard water.
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.
The most common chemicals used to unblock sinks are Drano, hydrochloric acid, or caustic soda. Chemical drain cleaners can be effective at removing even the toughest clogs. They come in different forms, such as powder, liquid, or gel, so be sure to buy one that best suits your situation.
Yes, the heat these chemicals produce will break down the remnants of a clog, but likely only push them farther down your system to form a more dense clog in a harder-to-reach section of your plumbing. This leads to repeat clog offenses, repeat pouring, and the eventual ruin of your plumbing system.
The most likely cause of a sulfur smell or other bad smell coming from a drain is stuck food, and it's the easiest to fix. As food that gets clogged in a drain or disposal decomposes, it emits gasses that cause unpleasant odors.
Just like cooking oil, bleach is one of those things you shouldn't pour into your sink. You should also never use bleach to unclog your drains. Doing so can even burst your drain pipes, and you'll be left with a nasty and expensive mess.
Let hot water run for a minute to warm up the pipes. Drop in 1/2 cup of baking soda down the drain. Pour in 1 cup of vinegar, cover the drain with a plug and let sit for 10 minutes – you will hear fizzing. Rinse with more hot water.
