A smelly sink is usually caused by bacteria build up from grease, fat and food which have been flushed down the drain. These will then get stuck in the pipes causing the familiar rotten egg smell.
If your drain smells like rotten eggs, you must disinfect the pipes to get rid of the odor. You can eliminate the bacteria by pouring a ½ cup of bleach down your drains. However, if you would like an alternative, pour down ½ a cup of baking soda and 1 cup of vinegar.
Boiling water poured into the drain is a quick cleanser for minor odors. A baking soda, vinegar, and boiling water combo can add extra power for breaking up the buildup in your drain's pipes. Periodically adding baking soda down your drain can keep the sink fresh and odor-free.
A slow-draining sink clogged with ordinary hair and soap scum can build up bacteria in the P-trap until your bathroom sink smells like rotten eggs. This smell can also happen in sinks that haven't been used for a long time. Clear the clog by using a combination of baking soda, white vinegar and hot water.
Baking Soda and Vinegar
While your water is heating, pour one cup of baking soda and one cup of vinegar down your drain, and let the mixture sit. After about ten minutes, flush the drain with boiling water. Finish up by flushing the drain with cold tap water, and wait to see if the odor is gone.
Pour Some Bleach in It: Bleach, like other disinfectants, kills almost every species of odor-causing bacteria commonly found in drains and sewer lines. So, an easy DIY step to reduce drain odor is to use bleach.
Loose connections along the vent pipe or sewer line can let pungent gases into your home. These will most typically be inside a wall or in the ceiling, requiring the help of an experienced plumber to correct this issue.
Baking soda is a base and vinegar is an acid; when the two are combined, you get a fizzy chemical reaction that has some properties that can eat away at a clog. However, when you use this combination to unclog a drain, it's just plain ineffective.
Vinegar contains acid which neutralizes odor, cuts through grease and helps disinfect. By heating up (but not boiling) four cups of vinegar, pouring half down the drain, running the water for a minute and then pouring the remaining vinegar down the drain, you can help eliminate smells and smaller clogs.
What you can do: Try this: put a couple teaspoons of baking soda in the drain and then pour in some vinegar. Then chase it with a pot of boiling water. The foaming of the baking soda/vinegar eats away at the junk in the drain and the boiling water helps wash it all away and sanitizes the drain.
There could be odor-causing bacteria feeding on debris in your pipes. This process will give off a foul-smelling hydrogen sulfide gas, which smells like sewage or rotten eggs. Also, mold grows where it's warm and wet — and mold growth on the debris causing a drain clog can also cause a bad smell.
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.
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.
It is safe to leave baking soda (and vinegar) to work overnight to unclog a drain. Always flush this mixture down with boiling water—no matter how long you leave it sitting in the drain.
Both baking soda and vinegar are highly caustic. They are, in fact, able to dissolve certain materials that one would not normally think of as being dissolvable. However, the extreme amounts of acid in vinegar, along with its acidic nature, are what cause the drain to become blocked.
A monthly cleaning will allow you to use safe cleaning methods which will save you time, energy and money in the long term. Combine 1 cup of vinegar, 1 cup of very hot water, and 1 half cup of baking soda and pour the mixture down the drain.
You can also add a mixture of baking soda and vinegar along with hot water to help get rid of the odor. Pour one cup of baking soda down the drain followed by one cup of white vinegar. Let the mixture sit for about 10 to 15 mins and flush with hot water. After this you should have an odorless clean drain!
A smelly sink is usually caused by bacteria build up from grease, fat and food which have been flushed down the drain. These will then get stuck in the pipes causing the familiar rotten egg smell.
The health risks linked to sewer gas exposure include: Hydrogen sulfide poisoning: Hydrogen sulfide smells like rotten eggs, even in low concentrations. Exposure to low levels of hydrogen sulfide can cause eye and respiratory irritation.
Step 1: Mix 1/2 cup baking soda with 1/4 cup table salt. Step 2: Pour the mixture down the drain. Step 3: Pour 1 cup heated vinegar down your drain; the concoction is going to foam and bubble. Step 4: Let the solution stand for 15 minutes (longer does not work any better).
BLEACH DOESN'T CLEAR DRAIN CLOGS.
It cannot dissolve things like food waste, breadcrumbs, grease, and hair. Instead, pouring bleach into a clogged drain will make things worse. The bleach could react with other chemicals, creating dangerous fumes, and if the reaction is violent, it can even burst your drain pipes.
Use a Mixture of Vinegar, Baking Soda, and Hot Water
Then cover the drain opening and let it sit for 15-minutes. After this, pour boiling water down the drain to flush it out. A mixture of baking soda and vinegar can be used to clean drain openings and remove bacteria and mineral deposits from your faucets, too.
Although mixing vinegar and baking soda is not considered dangerous, you should still avoid mixing these in a container. Vinegar is acidic and basic soda is basic, so the by-products are sodium acetate, carbon dioxide, and water that are not toxic.
