A perfect home should look clean and smell fresh all day long. With regular housekeeping chores and a bit of elbow grease, you can get rid of visible dust, dirt, spills, stains, grime and mould from almost all surfaces around your home. However, many people overlook nasty smells lingering in rooms.

If there is an odour of rotten egg smell in your home, inspect all your rooms immediately and treat it as soon as possible. It could be due to gas leakage or drained pipes. The best thing you can do is detect the source of the rotten egg smell and use eco-friendly ways to banish it.

You can also hire professionals for a detailed bond cleaning in Brisbane at the end of your tenancy. They will transform the entire property to help you impress a fussy landlord or property manager.

If you want to banish the rotten egg smell from your home on your own, consider the tips shared below in the article.

Let’s Get Started!

Causes of Rotten Egg Smell in a Home

This unusual smell is of chemical gas called hydrogen sulphide. It is produced when bacteria and germs break down the sulphate in the egg into organic matter. The absence of oxygen produces a foul smell. You can witness these smells in your bathroom and kitchen for various reasons, such as leakage of gas, decomposition in sewer systems, etc.

1. Gas Leak

Rotten egg smell could be a gas leakage if you have any gas appliance, such as a stove. This is a severe problem, and make sure you immediately call your utility service provider or the fire department in Brisbane.

The odour could be coming from any number of things, such as a problem in the water heater, a gas line issue with your stove, etc.

2. Drain Pipes

If you don’t use a bathroom a lot, you might be smelling methane right from your sewer gas filtering inside your sink or tub. This happens because of the p trap. It is a “u” shaped pipe under your sink or tub.

There is a small amount of water in it, which prevents the sewer gas from getting inside. But, if you haven’t used the sink or tub, the p trap gets dry completely and allows the sewer gas to get in and spread unpleasant odour.

Fortunately, there is a great fix to this problem. All you need to do is to detect the smell of rotten eggs in your bathroom. Now, run the water in the sink or tub for 10 minutes to allow the p trap to get some water in it.

That will stop the sewer gas from coming in. You can also call a plumber for professional assistance. Also, keep your garbage disposal clean to get rid of the stinky smell from your kitchen.

3. Dry Wall

Drywall could be the reason for the rotten egg smell, and it is because they contain an excessive amount of sulphur, which can linger unpleasant odour in your home.

According to experts, it is good to check the copper coils in your refrigerator and air conditioner. If you encounter black ash behind the appliances, it is due to the corrosion caused by off-gassing. You can resolve this issue by replacing your drywall.

Steps to Remove Rotten Egg Smell From your home

If you are still witnessing this unpleasant smell, follow these steps and make your home smell fresh again:

Step1: Arrange Cleaning Supplies

Do not forget to stock up all the necessary cleaning supplies if the smell still lingers from your floors and other hard surfaces. Ensure you have an abrasive detergent and scrubber, sponge, microfiber cloth/mop and warm water.

Step 2: Apply detergent on the surface.

The next step is to banish the rotten egg smell from the affected surface. Pour a tablespoon of detergent on the scrubber and scrub the surface thoroughly. Do this with gentle hands and scrub in a circular motion.

If your entire rented property needs a professional bond cleaning in Brisbane, then search for the best company and get your full bond back with ease.

Step 3: Wash Properly

After scrubbing the surface, you need to wash it thoroughly. You can also use a mild cleaning agent if you have hardwood floors.

Step 4: Remove any blockages from the sink

The blockage may cause the growth of black spores or mould, which may linger foul smell in your kitchen or bathroom. Broken pipes could also be another reason for the same. So, you can use white vinegar, baking soda and other natural cleaning products to remove mould, grime and dirt.

Step 5: Use Hydrogen Peroxide

Mix 3 per cent of peroxide with 40 gallons of water and pour this mixture into the water heater if the smell is coming from it. Leave it for 2- 3 hours, and then flush it. This will help you remove the rotten egg smell by removing bacteria buildup in the water heater.

Step 6: Remove Accumulated Junk in Water Treatment systems

Your water treatment system may also spread a rotten smell if it is not working correctly. You need to remove the old filter from the appliance and clean it thoroughly using bleach to fix the problem.

Step 7: Wash the filter

Do not forget to wash the filter with plain water and place it back in the treatment system. You can also buy a new filter for effective purification or filtration of water.


Maintain a clean, shiny and fresh-smelling home using the right cleaning methods. With these tips, you can banish the rotten egg smell from your beautiful abode. If you are preparing the rented property for the final inspection, hire trained bond cleaners in Brisbane and secure your full bond money at the end of your tenancy.
