Many people use nail polish remover to clean their car headlights, but this can be a mistake. Nail polish remover contains acetone, which can cloud up plastic and eat into the surface. This can leave a thick layer that cannot be wiped off. To fix headlights clouded by nail polish remover, you can sand them down and polish them, but this is a time-consuming process.

What You'll Learn
Nail polish remover can cloud up plastic headlights
While nail polish remover can be used to clean car headlights, it is important to note that it can also cloud up plastic headlights. This is because nail polish contains acetone, which can liquefy and quickly solidify as it evaporates, leading to a cloudy appearance. This process can permanently cloud any type of plastic, including car headlights.
In some cases, individuals have used nail polish remover to spot clean their car headlights, only to find that the treated areas have become cloudy. This is likely due to the acetone in the nail polish remover burrowing into the plastic and liquefying it. While fine-grit sandpaper can be used to try and restore the headlight, it may not be possible to completely remove the cloudiness.
To avoid clouding up plastic headlights, it is recommended to use alternative methods for cleaning. One suggestion is to use alcohol remover instead of nail polish remover. Additionally, there are plastic polishes specifically designed for cleaning car headlights that can be effective in removing oxidation and restoring clarity. Wet sanding with fine-grit sandpaper can also be an option for removing light cloudiness.
If nail polish remover is used on plastic headlights and cloudiness occurs, there may be some ways to mitigate the issue. One suggestion is to use fine-grit sandpaper to try and remove the clouded layer of plastic. Starting with a lower grit, such as 400 or 500, and gradually increasing to a higher grit, such as 1500 or 2000, can help smooth out the surface and potentially reduce cloudiness. However, it is important to keep the paper wet and to rinse it frequently to prevent further damage to the plastic.
While nail polish remover may seem like a convenient option for cleaning car headlights, its potential to cloud plastic surfaces cannot be overlooked. It is essential to consider the risks and explore alternative methods or products specifically designed for cleaning car headlights to avoid permanent damage.

Acetone in nail polish remover liquefies plastic
Acetone is a key ingredient in nail polish removers and is responsible for liquefying nail polish. It is a solvent that breaks down the polish and liquefies it, allowing it to be easily wiped off. While acetone is highly effective in removing nail polish, it can also be harsh on the skin and nails, causing dryness and irritation.
Nail polish removers that contain acetone are often the most effective at removing nail polish, especially for gel nails or glitter polishes. Acetone gets in between the chains of the polymer (the polish) and separates them, making it easy to wipe away. However, acetone can also be too strong and damaging for some surfaces, such as car headlights.
Acetone in nail polish remover can liquefy plastic, which is why it is effective at removing nail polish. Plastic is a polymer, and acetone can break down the polymer chains, liquefying the plastic. This is why it is important to be cautious when using acetone-based nail polish removers and to avoid their use on certain surfaces, such as car headlights.
In the case of car headlights, using a nail polish remover with acetone can result in permanent cloudiness. This is because the acetone can eat into the plastic of the headlight, causing it to become cloudy and reducing its effectiveness. While some people suggest using fine grit sandpaper to try and fix the cloudiness caused by acetone, it is best to avoid using acetone on plastic headlights altogether.
To avoid damaging car headlights, it is recommended to use a plastic polish or alcohol to clean them instead of nail polish remover. While nail polish remover with acetone can be effective at removing paint or polish from some surfaces, it is not suitable for plastic as it can cause irreversible damage.

Sanding is required to fix acetone damage
Acetone, a common ingredient in nail polish removers, can be used to clear car headlights. However, it can also cause damage to the plastic, leaving the headlights cloudy. This is because acetone liquefies the plastic and rapidly solidifies as the acetone evaporates, causing the plastic to become cloudy.
To fix this, sanding is required. Sanding the headlights will remove the damaged layer of plastic and restore clarity. It is recommended to start with a fine grit sandpaper, such as 500 or 400 grit, and work your way up to a higher grit, such as 2000 grit. This process is known as wet sanding and can be done by hand or with a drill. It is important to use sandpaper intended for wet sanding, as regular sandpaper may fall apart.
After sanding, a plastic polish can be used to further restore and protect the headlights. It is also recommended to wax the headlights after polishing to protect the surface.
Additionally, it is important to note that acetone vapour can also be used to clear headlights. However, this method requires pure acetone and a modified steam cleaner to control the temperature and prevent melting or cracking the plastic.

Rubbing alcohol is a safer alternative
While nail polish remover can be used to clean car headlights, it is not recommended due to the risk of damage. The acetone in nail polish remover can eat away at the plastic surface of the headlights, causing cloudiness and permanent damage.
A safer alternative to clean car headlights is to use rubbing alcohol, which can be found in most stores. Rubbing alcohol is a gentler solvent that effectively removes dirt, grime, and light scratches from plastic surfaces without causing cloudiness or other types of damage.
If you choose to use rubbing alcohol, it is important to follow the proper procedure. Firstly, ensure that you are working in a well-ventilated area and wear protective gloves to avoid skin irritation. Apply the rubbing alcohol to a clean, soft cloth and gently rub it onto the headlight in a circular motion. Continue until the headlight is clean and free of haze.
After cleaning with rubbing alcohol, it is crucial to polish the headlights with a plastic lens polish to restore clarity and protect the surface. This process may take up to an hour for each headlight, so patience is essential. Additionally, remember to remove the rubber gasket surrounding the lens before cleaning, as it will make the task easier and prevent mess.
In conclusion, while nail polish remover may seem like a quick solution, it is not worth the risk of damaging your car headlights. Instead, opting for rubbing alcohol as a safer alternative will effectively clean and restore your headlights without causing permanent harm to the plastic surfaces.

Wet sanding and polishing can restore headlights
Foggy headlights are not only an eyesore but also a safety hazard. They impair your vision at night, putting you and your passengers in danger. The good news is that you can restore your headlights through wet sanding and polishing, without spending a fortune at the mechanic.
Wet sanding is an effective method to remove the foggy layer from your headlights and restore their clarity. It involves using fine-grit sandpaper, ranging from 600 to 2000 grit, to gradually sand down and smooth out the headlight surface. It is important to change the sanding direction with each grit progression, such as horizontal, vertical, or circular motions, to ensure even removal and prevent scratches. Additionally, applying consistent pressure and keeping the surface lubricated with water is crucial to achieving desirable results.
After wet sanding, polishing becomes the next crucial step in the headlight restoration process. Using a polishing compound and a flannel polishing cloth, you can buff the headlights to a sparkling shine. For added convenience, power tools such as a cotton buffing wheel or felt roloc polishing pads can be utilised. It is recommended to polish in consistent motions to achieve an even finish.
For headlights with moderate to severe haze, a combination of dry and wet sanding may be necessary. Starting with a lower grit, such as 400, can help remove deep scratches and severe haze. However, it is generally recommended to begin with a finer grit, such as 1000, to avoid creating more work during the refining process.
While wet sanding and polishing can significantly improve the clarity of your headlights, it is important to note that if the plastic exhibits fine cracks, known as "crazing," replacing the headlights may be the only permanent solution. Crazing occurs due to the age and stress on the plastic from expansion and contraction over time. However, as replacing headlights can be expensive, wet sanding and polishing can still be performed as a temporary solution to enhance their condition.
