7 Most Common Reasons of Why Toilet Smell Worse After Cleaning
When your toilet smells terrible, it might badly embarrass you in front of your guest. Otherwise, your little kids and family members can be disturbed while using it. But before you know how to get rid of toilet odor, find the cause behind this. So, what are the reasons for a smelly toilet? Let’s find out some.
Problem 1 of 7: Evaporation in P-Trap
If you’re getting a bad and sewage-like smell from the toilet that’s rarely used in your home (guest washroom or outhouse toilet), or you’re using it after a long vacation, then you should blame evaporated water in P-trap.
P-trap is a part of the pipe behind your toilet. Usually, it remains filled with water and helps to prevent sewer gas from escaping. But when your toilet isn’t used regularly, the water gets low and causes evaporation. Thus the sewage gas comes out and fills your toilet with a worse smell.
In this case, you should flush the toilet regularly, even if you’re not always using it. Flushing frequently will allow the water to remain filled in the P-trap and will block the sewer gas from coming out.
Problem 2 of 7: Damaged Wax Seal
Another complex reason behind the bad smell of your toilet can be a damaged wax ring seal. This ring is situated underneath the toilet to keep it in place and prevents sewer gas from getting into your toilet.
However, the wax seal can be loosen or damaged when it becomes old. Thus, sewer gas leaks through the cracks and makes your toilet nasty-smelly.
If your toilet becomes loose and starts moving when you sit on it, you’ll know something wrong is happening with your wax seal, and it’s time to replace it.
If your wax seal is damaged and leaking, you need to replace it as early as possible. But if you’re not experienced with it, don’t try to fix it yourself. Instead, call a plumbing professional to install a new wax seal. Hopefully, you’ll get rid of the foul odor after replacing it.
Problem 3 of 7: Sewer Bacterial Growth
Microorganisms or bacteria usually remain in sewer pipes. But sometimes, they make their way from the sewer to up into your toilet bowl. And to save life, the bacteria cling to the rim and begin to propagate.
Once the bacteria starts growing, it spreads foul gasses throughout your toilet. Even if you clean the bathroom, the smell is still there. You’ll face this problem mainly during the hot summer season as this soggy condition helps bacteria thrive.
Luckily, you can boot these bacterias quickly with some bleach following these simple steps.
- Pour several cups of bleach into the flush valve or overflow pipe. A flush valve is placed inside your toilet tank.
- Next, flush the toilet a few times. After flushing, the bleach you poured in the flush valve will release around the rim and run down through the side of your toilet bowl. Thus, it effectively wipes away the microorganisms, and the nasty-smelling also disappears quickly.
Problem 4 of 7: Vents That Are Clogged up
It’s normal to have a slight sewage odor after using the toilet. But when the smell leads stronger and persists, you should check the Toilet Vent Pipe whether it’s clogged or blocked.
Every toilet has a vent pipe to keep them ventilated and allow foul odors to escape outside. It lets the air enter the system so the waste water can freely flow.
But when the vents get clogged or blocked, the ventilation system doesn’t work. So, the unpleasant smell formed into your entire toilet and became the reason for your headache.
The vent pipe can be blocked for the following reasons:
- By pile
- By a dead bird
- By bird nest
Or the vent gets clogged due to:
- Soap scum
- Or frost in cold weather
As the clogging happens, it’ll require some tools for unclogging. So, we recommend calling a plumber who can understand the condition of the vents. Plumbers will use their devices to remove the clog safely, and the odors will go away.
Problem 5 of 7: Dirty Toilet Tank
Though you regularly clean your toilet bowl, sometimes your toilet tank can be responsible for the sewage smell. Toilet tanks can absorb the nasty odors of sewage gas and urine and release a strong urine smell. So, the toilet smells like urine despite cleaning. For details, you can check this article; Does the toilet smell like urine?
Fortunately, you can clean the toilet tank yourself without any hassle. You’ll only need:
- 1 cup of white vinegar
- A toilet brush
Vinegar is an excellent smelly toilet remedy for cleaning your home and bathroom. It contains acetic acid that helps to neutralize the source of the odor. This acid also effectively disinfects the properties.
Following these steps, you can immediately get rid of foul odors coming from the toilet tank.
- Pour the white vinegar into the tank
- Take a toilet brush to scrub inside the tank.
- Scrub around the wall of the tank and the bottom.
- Now, let the vinegar sit for 5-10 minutes.
- Flush the toilet multiple times to move down the water away from the tank
Problem 6 of 7: A Crack in the Toilet
Another common reason for worse smelling in a clean toilet can be the crack in the toilet bowl. Notice whether there is a tiny hairline crack in the bowl or not. If it’s there, it can lower the water level. As a result, the water will leak to the drain and subfloor area, causing a bad odor in the toilet.
In this situation, you may need to replace the toilet to fix the problem. So, contact a plumber as soon as possible before your toilet floor gets damaged or even worse.
Problem 7 of 7: Clogged Toilet Drain
Sometimes your toilet drain can be clogged with some unusual things like hair, soap, toilet paper, cat litter, etc. In that case, it won’t remove only flushing since the clog begins to emit the smell throughout your toilet.
There are multiple alternative ways to fix this issue. For example
Method 1: Using a snake
You can use a toilet snake or plunger to unclog the drain of your toilet.
Method 2: Hot Boiling Water
Pour a few cups of hot water into the toilet bowl and leave it there for a few minutes. After that, flush the toilet several times to ensure the clog goes down in the drain.
Method 3: Baking Soda and Salt
Pour 1 cup of baking soda and ½ cup of salt into the toilet drain. Leave it to sit for 4-5 hours. Next, pour 2 cups of hot water and flush the toilet to remove clogs as well as odor from the drain.
