Why Is There a Strange Acetone Smell in My House?

If you encounter an unfamiliar smell, naturally, you will search for its origin. Each scent originates from a unique source, therefore not every smell indicates the same thing.

The experience with the acetone smell can be somewhat perplexing. A characteristic floral smell can signal something regularly, but it may also signal danger.

For this reason, it is critical to identify the source of the smell and get rid of it.

What’s the Reason Behind the Strange Acetone Smell in My House?

What does it mean when your house smells like nail polish?

A strange acetone smell in houses can stem from a variety of reasons. Let us explore some of the primary causes that may result in this issue.

Remember, the first step is to find the source of the odor (see all of the steps below).

The second step is to remove the smell with an oil diffuser or air purifier.

1. Mildew and Mold

The presence of mold and mildew in your home may, strangely enough, emit a pungent odor.

Whether it is in the basement, kitchen, or bathroom, mold and mildew build-up can cause a strange, pungent fragrance. 

Mold and mildew result due to the presence of water, fluid, and moisture in certain areas of your home.

While the scent of mold and mildew may seem sweet and pleasant, it can still be injurious to your health and hygiene.

2. Caulk

If you’ve ever noticed a strong, acetone-like smell in your home, chances are that it could be coming from your caulking or silicone-based sealants. 

People commonly use a variety of caulks and sealants to patch up cracks and holes in their homes. 

However, what many people don’t realize is that these materials can produce an unpleasant smell that lingers for days or even weeks. 

When exposed to air, acetone quickly evaporates and diffuses into the surrounding air, where it can be detected by the human nose.

In high concentrations, it can cause headaches, dizziness, and nausea.

2. Refrigerant Leakage

A strange acetone odor in your home may also result from a refrigerant leakage situation. Refrigerant is a substance that aids in the proper operation of a refrigerator. 

If your refrigerant leaks, it can give off a strange acetone smell.

If the leak is not fixed immediately, it can lead to serious medical problems as the refrigerant contains some hazardous components.

3. Air Conditioner Leakage

Why Does My House Smells Like Nail Polish Remover?

Like refrigerants, air conditioners too come with a liquid that helps aid proper function.

If this air conditioner liquid escapes, your house may smell strange and nail polish-like. 

Air conditioning leakages occur when formic acids from various parts of your home combine with the copper in your air conditioner.

4. Sewer Gas Leakage

The acetone smell in your house can be produced by sewer gas leakage. Sewer gas is a mixture of different gasses that are released from the sewage system. 

This gas can contain methane, carbon dioxide, and other chemicals. 

When these gasses leak into your home, they can produce an acetone smell. In addition to being unpleasant, this gas can also be dangerous.

5. Faulty Wires

If you notice a faint acetone smell in your house, it may be due to faulty electrical wiring. 

This is because the insulation on electrical cables can degrade over time, releasing chemicals like acetone into the air. 

While this isn’t necessarily a fire hazard, it can be a sign that your electrical system is in need of repair. 


How can you get rid of the strange acetone smell from your home?

If you know the root cause of the issue, you can direct your eradication efforts accordingly to get rid of the smell.

What to do if the smell is due to mold?

If the strange acetone smell is the result of mold and mildew build-up, you must clean them to eliminate the smell. 

Clean any areas that are exposed to persistent wetness like the kitchen, bathroom, and basement, for example.

Cleaning carpets, rugs, mats, and other such items can also be beneficial.

How to fix refrigerator and air conditioner leaks?

Acetone is a by-product of the breakdown of chlorofluorocarbons (CFCs). 

When these chemicals leak from air conditioners, refrigerators, and other appliances, they spread a strange acetone smell within their surroundings. 

If your refrigerator is leaking, it could be a sign that the seals around the door gaskets need to be replaced.

The gaskets create an airtight seal that helps to keep cold air in and prevent warm air from entering.

Over time, the gaskets can become worn or cracked, allowing cold air to escape and warm air to enter. 

As a result, your refrigerator will have to work harder to maintain the proper temperature, which can lead to excessive ice buildup and water leaks. 

Fortunately, replacing the door gaskets is a relatively easy repair that you can do yourself. Simply remove the old gaskets and install new ones in their place. 

Be sure to clean the surface of the door where the gaskets will be installed to ensure a tight seal.

With new gaskets in place, your refrigerator should be able to maintain the proper temperature without leaks.

How to get rid of sewer leakage?

If you suspect that you have a sewer gas leak, there are a few things you can do to fix the problem.

First, check all of your drains and toilets to make sure they’re not blocked. If they are, clear them out and see if the smell goes away.

Next, check your vents and make sure they’re not blocked or covered.

Finally, if you still have a sewer gas smell after taking these steps, you may need to call a professional to come and take a look. 

Don’t ignore sewer gas leaks – taking action now can help keep your family safe and healthy.

Can I fix the ventilation problem?

You can remedy a ventilation problem by ensuring that the house has adequate ventilation.

Open the house’s doors and windows and switch on the fans to allow air circulation.

I am experiencing chemical odors. What to do?

If you notice other gasses or substances that have a strange fragrance in your home, you should seek professional help because you may not be aware of how hazardous the fumes or chemicals are.
