My House Smells Like Paint Thinner or Nail Polish

House Smells Like Paint Thinner! (Causes & Solutions)

The house can smell like a paint thinner, especially if the house is just recently painted. The paint thinner has volatile organic compounds that produce a pungent smell during air exposure.

Some of the chemicals in the paint thinner include mineral and genuine turpentine, toluene, acetone, xylene, and dimethylformamide.

These chemicals pose a significant risk to the health of the house’s occupants.

Paint thinners serve as solvents to thin oil-based paints. Most solvents that serve as paint thinners have a flash point of about 104 degrees Fahrenheit.

The flash point is the minimum temperature at which liquid gives off vapor in a concentration sufficient to form an explosive mixture.

Therefore, the lower the liquid’s flash point, the easier it is to ignite the liquid solvent.

Painting the nails with nail polish can leave the house with a long-lasting smell. Nail polish has a fruity and pleasant smell.

However, the acetone in nail polish produces a pungent odor when it escapes into the air. This same smell is found in nail polish remover, although it is more potent in nail polish.      

How to Get Rid of Paint Thinner Smell In the House?

To get rid of the paint thinner smell in the house, you need to get rid of the source of the smell.

After getting rid of the source of the smell, you can then open your windows so that the remaining smell will go out and the house will be free. 

Since the significant paint thinner smell is from a recently painted room, ensure that all the materials used in painting the room are washed, cleaned, and dried.

If you cannot use them again, dispose of them properly in a sealed bag to conceal the smell before putting them in the trash can.

Paint thinner contains volatile organic compounds that escape into the air on exposure. When it evaporates, it produces a strong smell that can irritate the sensitive parts of the body.

To avoid this, choose paint thinners with low or no volatile organic compounds. There are several paint thinners around that can suit your preference.

You can get this product from the market or online stores. Also, you can reduce the concentration of smell from the source.

You do this by reducing the number of chemicals in the paint thinner. Additional chemicals added should be taken care of properly.

#2. Water 

Water is easily accessible. Like vinegar, put some water in bowls and leave it open in the house or room you just painted for about 8 hours.

The water will neutralize the smell by absorbing some of the chemicals. You can dispose of the water afterward in a sink. It is the simplest method of removing the smell of a paint thinner.

#3. Baking Soda        

Baking soda is known for removing odors naturally, especially in freezers and rugs. It is proven to remove any unwanted smell, and the paint thinner smell is no exception.

t is advisable to allow proper ventilation from the start of painting the house till the finishing time. With this, the smell in the house will reduce and go out with time.

However, if it is from a leaking air conditioner or freezer, not the paint thinner itself, you should see a professional.

Heating, ventilation, air conditioning, and refrigeration (HVACR) technician has the skills and experience to repair any leaking appliances.

The technician will come and inspect the cause and the source of the leak and repair it. A component of the appliance might need to be changed or repaired.

Also, suppose the smell is from nail polish remover when an occupant of the house recently removed the polish on his nails.

Joint Reasons House Smells Like Paint Thinner.

There are different reasons why a house smells like paint thinner. Apart from the smell that can come from the paint thinner itself, there are also other sources of the smell.

Below are some of the reasons:

#1. Paint Thinner

Leak In the Air Conditioning System

The smell of paint thinner around the air conditioner is a bad sign which shows something is wrong.

Most times, the smell results from a leak in the air conditioner. With consistent usage, the coils in the AC can break down and stop working, causing the refrigerant of the AC to start leaking.

The air conditioning system uses chemicals to convert liquid to gas and then liquid. They also convert the hot air in the room to cool air. Unfortunately, the chemicals can become worse over time and start leaking.

Below are some of the ways to ascertain if the leak is from the air conditioner:

  • If the AC is no longer or barely cooling your house, you should check for a leak.
  • You should check for leaks and other abnormalities if there are strange, unfamiliar AC sounds.
  • The presence of ice on the lines and coils signifies a leak in the air conditioning system.

#2. Leaks From the Refrigerator

The refrigerator operates a cooling system similar to the air conditioning system. However, an old refrigerator can start leaking a chemical called freon which is hazardous to people’s health.

Leakage from the refrigerant affects the effectiveness and efficiency of the refrigerator’s cooling system.

A professional is a solution to this type of problem, and a replacement with a modern generator will be advisable.

#3. Nail Polish Remover

The nail polish remover has an unpleasant smell that smells like paint thinner. It is because the polish remover contains strong chemicals like acetone.

Though the smell may vanish with time, it may not be comfortable for the house’s occupants.  

#5. Clogged Bathroom

Though rare, the bathroom can smell like paint thinner when clogged up with dirt. In addition, the air from the blocked pipes or drainage system can cause foul smells from chemicals. The solution is to fix all the lousy drainage systems in the house.
