Why Does My Laundry Room Smell Like Rotten Eggs?

Most people would agree that one of the most unpleasant smells is rotting eggs. Unfortunately, if your laundry room smells like this, it can be a sign that you have a gas leak. 

In this blog post, we’ll explain why your laundry room might smell like rotten eggs and what you can do to fix the problem. 

Why Does My Laundry Room Smell Like Rotten Eggs

How to get rotten egg smell out of laundry room

The production of hydrogen sulfide gas causes the rotten egg smell.

Detergent gathers on rubber parts of your washing machine when you don’t clean it often enough, and those areas develop breeding grounds for nasty bacteria. 

Causes of the Rotten Eggs Odor

The cause of that terrible rotten egg smell you keep getting every time your laundry cycle finishes is due to bacteria growing on organic matter in the drain.

A clogged washing machine pipe caused by debris has been producing an odor all this while.

The other cause of the Rotten Eggs odor is a plug that’s been lost, probably due to heavy rains overwhelming its drainage system and causing flooding in your home.

Sewer gas has seeped up from below through either an exposed drain or one where there’s been too much drying out.

Ways to Get Rid of the Rotten Egg Smell in Your Laundry

It is important to wear protective gear when working with harsh chemicals or any form of mold removal.

Although there are many ways you can get rid of the odor’s source, these are the most appropriate options;

Inspect Your Drains and Pipes

Spilling a tiny amount of water down the pipes will tell you if there is an issue with any component, such as clogged drains/legs on a sink (which causes flooding).

If you notice any problems, like slow draining or leaks that a break in the pipe could cause, get them fixed as soon as possible before the gas gets into your home.

Physically Clean All of the Washing Machine’s Surfaces

Physical cleanliness is always key when trying not to have any stench or stains adhering themselves onto fabrics, so make sure everything is spotless before putting anything into their wet clothes. 

Examine all areas that might hold smells, from under the washing machine and around ventilation grates on top for dust balls to glove compartments where mold is most commonly found.

Clean these surfaces with bleach or a deodorizer before restarting your laundry process, so no more unpleasant odors escape into clothing (or house). 

You could also try wiping down any visible signs like splashes/ marks etc., then drying thoroughly after use; this will help reduce potential growth spots.

Drainage Line Cleaning and Unclogging

A buildup of soap scum, filth, and lint causes blockages which you can clean by cleaning any clogs that may prevent water from draining. 

It is very important for reducing odor issues on your washing machine during operation and minimizing bacteria exposure while ensuring you’re able to continue using it without issue. 

To start cleaning the washing machine, you’ll need:

  • wire hook (for unblocking drains)
  • boiling tap water instead of cold if possible
  • removal tool such as pliers/vice grip needle nose pliers, etc.

Flip open drain cover underneath sink before removing the old one, so it doesn’t get lost.

Remove any Accumulated Scum with Vinegar

Vinegar’s natural acidity will kill bacteria and viruses on your laundry, even though detergents or bleach are also effective at getting rid of dirt.

Fill up one cup in the washer instead, then run a complete cycle to make sure everything gets clean. This will eliminate mold spores and germs, eliminating future rotten egg odors in your laundry room.

If you dilute it with one cup of water beforehand, you may also be able to get rid of the rotten egg smell from your laundry.

Is the Odor of Rotten Eggs Harmful to Your Health?

How to get rid of sewer smell in laundry room

Hydrogen sulfide gas causes the rotten egg odor, and it naturally occurs in natural gas.

The gas is also formed by the bacterial decomposition of animal and human waste (sewage) and organic items like manure.

The gas is hazardous to both your health and that of your animals.

Sewer Gas

Sewer gas is produced by decaying solid waste and contains ammonia, methane, and hydrogen sulfide, which are highly harmful to pets and people when breathed. 

Sewer gas in high concentrations can be fatal. Even minor exposure might affect the body.

Natural Gas

When it comes to natural gas, everyone knows one thing: the odor. Mercaptan gives off this distinct smell and can be found in most forms of modern-day life, such as homes or even your kitchen. 

Rotten eggs and sulfur have a similar odor as mercaptan.

Natural gas in low amounts is not dangerous, but lengthy exposure can damage your health. A gas leak decreases the quantity of oxygen in the atmosphere, resulting in less oxygen whenever you breathe.

Frequently Asked Questions

What is Causing My Room to Smell Like Rotten Eggs?

The two most prevalent causes of rotten egg smell in the home are electrical components or a natural gas leak.

Mercaptan smells like rotten eggs, and natural gas manufacturers add it to detect leaks. 

Does Carbon Monoxide Have a Rotten Egg Odor?

No, some fallacies surround carbon monoxide detection methods, such as distinguishing the pungent odor of rotting eggs. Carbon monoxide gas has no odor and cannot be detected.

Final Thoughts

The problem of a laundry room smelling like rotten eggs is very simple and can be prevented from happening again in the future. 

Take safety precautions when handling harsh chemicals. If possible, do not enter your premises for hours after use with bleach or other detergents as their presence may cause an issue further downline.

Keep children away because they could disturb something stuck on fabric, leading you back towards these problems even sooner than expected. And of course, keeping them clean will always come first.
