To get rid of a drain smell, start by checking where the odor is coming from. Pour 1/4 cup of baking soda down the drain, follow with 1 cup of white vinegar, and let it fizz for 15 minutes. Flush thoroughly with a kettle of boiling water.
How to stop the smell
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.
Items to Never Flush or Pour Down the Drain:
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.
Generally, you should only flush toilet paper and your body's waste. Water and anything typically mixed with water, such as toothpaste, soap, and shampoo, are the only products that should go down our sinks and shower drains.
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.
Pouring vinegar down your sink is a great natural method for cleaning pipes. The acidity of white vinegar helps dissolve minor grease buildup and soap scum, neutralizes foul odors, and clears away light mineral deposits without the harsh chemicals of commercial drain cleaners.
Salt itself will not chemically damage PVC pipe; the material is chemically inert and highly resistant to saltwater and brine. However, salt can indirectly cause issues for your plumbing system. While the plastic remains unaffected, salt can corrode connected metal fittings, dry out joints, or potentially damage downstream fixtures like water heaters.
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.
Use vinegar and baking soda
Vinegar and baking soda are some of the best remedies to use when you want to fight sewer odors from the drain. Mix a cup of baking soda and vinegar and pour it down the drain. Leave it on for about half an hour and then rinse thoroughly with warm or boiling water.
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.
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.
While you can technically pour small amounts of diluted bleach down a sink to kill bacteria causing odors, it is generally not recommended by plumbers. Bleach can damage pipes, erode seals, create dangerous fumes if mixed with other cleaners, and kill beneficial bacteria in septic systems.

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.
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.
While white vinegar is an excellent natural cleaner, its acidity means it can damage certain surfaces, strip finishes, or cause rust. You should generally avoid using it on:
Yes, Dawn dish soap can help unclog drains, but primarily only for minor blockages caused by grease, soap scum, or oily residue in kitchen and bathroom sinks. Its powerful degreasing properties work to break down the fats causing the restriction, especially when paired with hot water.
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.
Pouring salt down drains at night is a popular home remedy meant to naturally deodorize pipes, break down minor grease build-ups, and deter pests like drain flies. It is done at night so the mixture has hours to sit undisturbed without being washed away.
Specialised Recycling
Bedsheets & Linen in good condition are often collected in door-to-door collection drives and cash for trash events. Items that don't meet their quality standards may be rejected or sent for incineration.
It's also better for the environment, as plastic pollution is a leading global threat, and only 3-5% of prescription bottles are recycled, according to Pavł Polø.
No, you should never pour nail polish down the drain. Nail polish contains toxic and corrosive chemicals that the EPA classifies as household hazardous waste. Dumping it into your plumbing can harden inside the pipes, cause severe clogs, and dissolve or damage plastic PVC pipes.
