WD40 is a versatile lubricant that can be used as a cleaning solution for car headlights. Its water-repelling properties make it ideal for removing dirt, grime, and rust from headlight lenses. To use WD40, spray it onto the headlights and scrub with a soft-bristled brush or microfiber cloth. Then rinse with water and dry with a clean towel.
Bug spray is another option that some people swear by for cleaning their car’s headlights. Its main ingredient, DEET (N, N-diethyl-m-toluamide), effectively dissolves insect residue.
What Is A Bug Spray?
Bug spray is a type of insecticide specifically designed to eliminate or repel insects. The active ingredients in bug sprays are typically chemicals that are toxic to bugs, such as pyrethrins or permethrin. These chemicals disrupt the nervous system of insects, causing paralysis and eventually death.
Pros Of Bug Spray On Headlights
Not Costly:
Bug spray is a cheap and easy solution for removing grime, dirt, and bug splatters. Most bug sprays contain ingredients that can break down the build-up on headlights, making them clear and bright again. It’s also readily available in most households or gas stations.
Convenience:
Unlike WD-40 or other specialized headlight cleaning products, there’s no need to purchase additional tools or equipment . Simply spray the solution onto the affected area, let it sit for a few minutes, and then wipe it away with a clean cloth.
Less Harmful Chemicals:
Bug spray contains fewer harmful chemicals than other cleaning agents in the market. Bug sprays are generally safer for car surfaces than harsher chemicals in other cleaning agents like acetone or bleach-based products.
Cons Of Bug Spray On Headlights
Can Cause Damage:
One of the biggest cons of using bug spray on headlights is that it can damage the plastic lenses over time. The chemicals in bug sprays are not meant for automotive surfaces and can cause discoloration, clouding, or even fading of the headlight covers.
Leaves Greasy Residue:
Another downside of using bug spray on headlights is that it tends to leave a greasy residue that attracts dirt and grime more quickly. This means that you’ll have to clean your headlights more frequently, which is time-consuming and expensive if you have to replace them due to damage caused by the bug spray.
What Is WD40?
WD-40 is a popular lubricant and rust dissolver that has been around for over 60 years. The Rocket Chemical Company created it in 1953 to prevent corrosion in nuclear missiles. Still, it quickly found its way into households as a multi-purpose solution for squeaky hinges, sticky locks, and other household issues. WD-40 stands for Water Displacement – the 40th formula that was finally successful.
Pros Of WD40 On Headlights
Can Remove Stains:
One significant advantage of using WD 40 is that it can remove stubborn dirt, oil, grime, and stains on headlights. This versatile lubricant works wonders in eliminating oxidation and yellowing of plastic headlights, which can make them appear dull over time.
Provides Protective Layer:
Another benefit of using WD 40 on headlights is that it protects against future damage. Once applied to the surface of the headlight lens, it forms a barrier that prevents dirt buildup and moisture from penetrating the lens. As such, your car’s headlights remain cleaner for longer periods.
Cons Of WD40 On Headlights
Cause Discoloration:
One of the biggest cons of using WD-40 on headlights is that it can cause discoloration and damage the plastic lens cover over time. This is because WD-40 contains harsh chemicals that can react with and break down certain types of plastics, leaving them cloudy or yellowed.
Not Effective In Thorough Cleaning:
Another drawback to using WD-40 on your car headlights is that it doesn’t clean them well. While it may remove some dirt and grime from the surface, it won’t eliminate any built-up oxidation or haze accumulated over time. You’ll need to reapply the product frequently to maintain a clear shine on your headlights.
What Is Best For Car Headlights? WD40 Or Bug Spray?
Neither is ideal for cleaning car headlights. While it’s true that both these products can help remove dirt and grime from your headlights, they can also damage the plastic lens and leave a residue that attracts more dust and dirt.
Many affordable headlight cleaners offer better results than WD40 or bug spray. These cleaners are formulated to clean without damaging the plastic lens and protect against UV damage. Invest in a good quality headlight cleaner instead to keep your car looking new and ensure safe driving at all times.
Can WD-40 Clean Foggy Headlights?
Using WD-40 to clean foggy headlights is a popular DIY solution that promises to remove the oxidized layer that causes the haze. The process involves spraying WD-40 on the headlight and scrubbing it with a cloth until the discoloration disappears. However, while this may work temporarily, it is not a long-term fix. The chemicals in WD-40 are not designed for cleaning purposes and can damage plastic parts over time.
What Spray Can Clean Headlights?
Use a commercial headlight cleaner spray: These sprays contain special chemicals that break down the buildup on your headlights without damaging the plastic lens cover or causing any harm to your car’s paintwork. Some brands even have polishing agents that remove scratches and make your headlights look brand new.
Use household items like vinegar or baking soda mixed with water: These solutions are natural alternatives to chemical sprays and work by breaking down the dirt particles on your headlights’ surface.
How To Clean Headlights With Bug Spray?
Spray the bug spray onto a microfiber cloth and wipe away any debris from the headlights. For tougher stains or buildup, let the bug spray sit on the headlights for several minutes before wiping it off.
How To Clean Headlights With WD 40?
Spray some WD-40 onto a clean cloth and wipe the headlight lens thoroughly. Make sure to cover the entire surface of the lens with the product and allow it to sit for a few minutes.
Afterward, use another clean cloth to remove any excess WD-40 from the lens. You should notice an immediate improvement in the appearance of your headlights after this simple treatment.
Conclusion
While WD-40 and bug spray can be used to clean car headlights, the two have some important differences. WD-40 is specifically designed as a lubricant and penetrant, making it effective at breaking down grime and dirt on the surface of the headlight. On the other hand, bug spray contains chemicals that can dissolve insects and their residue that may have accumulated on your headlights.
It’s important to note that using bug spray on your car headlights may cause damage over time. The chemicals in most bug sprays are strong enough to eat away at plastic surfaces, which could lead to cloudiness or even cracking. In contrast, WD-40 is safe for use on plastics and won’t cause any damage when used properly.
