Yes, pouring vinegar down a drain is an effective, natural way to eliminate odors. It helps break down the buildup of odor-causing bacteria, soap scum, and minor clogs. For the best results, use it alongside baking soda and hot water.
Pouring a mixture of 12one-half12 cup of baking soda followed by 12one-half12 cup to 1 cup of white vinegar down the drain is a highly effective way to neutralize foul odors. The foaming reaction acts like a natural scrub to break down bacteria and sludge inside the pipes.
For a quick and natural way to freshen a smelly drain, pour 1/2 cup of baking soda down the sink, followed by 111 cup of white vinegar. Let the mixture fizz for 10 to 15 minutes to break down grime, then flush the pipes thoroughly with a kettle of boiling water.
Acidic vinegar, particularly when used with baking soda, can wear down the rubber seals on your pipes. It's not just your actual pipes you have to be cautious of when unclogging drains.
You can also deodorize drains and help smelly drains with a combination of baking soda and vinegar. These ingredients, when used together, can also sometimes help to clear drain clogs.
Pouring salt down your drain at night is a popular DIY plumbing trick used for routine maintenance. The goal is to take advantage of the salt's coarse texture and natural moisture-absorbing properties.
Eliminating a sewer smell requires tackling the root cause. Start by running water down unused drains to seal the pipes. For persistent odors, clear the drain with a DIY mixture, clean the overflow, or replace worn plumbing parts.
Items to Never Flush or Pour Down the Drain:
Leave the baking soda and vinegar mixture in your drain for 15 to 30 minutes for regular maintenance. If you are targeting a tougher clog or a stubborn odor, letting it sit for 1 to 2 hours or overnight is recommended.
A straightforward yet effective approach to addressing a clogged drain pipe involves simply using hot water mixed with dish soap. This method, ideal for tackling minor blockages, leverages the degreasing power of dish soap combined with the force of hot water to dislodge and dissolve clog-causing residue.
How to stop the smell
The characteristic "old age smell" is scientifically known as nonenal (or 2-nonenal). It is a chemical compound produced when the skin's natural oils and fatty acids break down and oxidize as we age.

2. Baking Soda, Vinegar and Boiling Water
As the fall rains intensify and the seasons shift, one surprising tip is getting renewed attention: pouring vinegar down your drains to help prevent clogs.
Pouring boiling water down your drain can soften and warp PVC pipes, weaken the glue in pipe joints, and damage rubber gaskets. Instead of clearing grease, boiling water just melts it, pushing it further down the pipe where it hardens and creates a stubborn, hidden clog.
Baking soda and vinegar do not effectively unclog drains. Instead of clearing debris, mixing them chemically neutralizes both ingredients into salt water. The fizzing reaction is visually satisfying but largely escapes upwards, offering zero power to dissolve grease, hair, or stubborn sludge.
Because vinegar is highly acidic, it can easily etch, pit, or corrode certain materials. You should avoid using it on natural stone (marble, granite, limestone), hardwood floors, cast iron, aluminum, electronic screens, and kitchen knives.
Plumbers highly recommend avoiding harsh chemical drain cleaners, as they can corrode pipes and only offer temporary relief. Instead, they suggest preventing buildup through daily habits, using natural enzyme or enzymatic cleaners for maintenance, and letting professional cleaners clear severe blockages.
Over time, repeated use of chemical cleaners can weaken pipe walls, warp plastic piping, and corrode older metal lines. This gradual damage often leads to leaks, cracked pipes, and sudden plumbing failures that require emergency repairs. Another problem is that drain cleaners do not solve the real cause of most clogs.
In plumbing, the "135-degree rule" is a code standard that dictates how much a horizontal drain pipe can bend or change direction. It limits the total cumulative angle of pipe fittings before a system requires an access point (cleanout) or must be vented, ensuring proper flow and preventing chronic clogs.

Some of the hardest and worst smells to get rid of are pet odours, mold, and cigarette smells.
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.
A foul sewer smell in a bathroom without a blockage is most commonly caused by a dry P-trap (allowing sewer gas to escape), a broken toilet wax seal, or a clogged roof vent pipe. The smell, often caused by bacteria buildup or methane release, can be fixed by running water in unused drains, cleaning the sink/shower drain, or replacing the wax ring.
