What Is WD-40?
WD-40 is a popular chemical that’s been around since 1953. The WD stands for “water displacement,” while the 40 represents the 40th version of the WD formula. Originally, WD was mostly used by the military, which cleaned missile parts with this solution.
Nowadays, people use WD-40 for squeaking hinges, cleaning rusty items, and various things around the home.
Most consider WD-40 a lubricant, although it’s not a true lubricant. However, WD-40 can act as a lubricant because it dissolves dirt, rust, and grime.
The Ingredient List of WD-40
WD-40 manufacturers keep the ingredients a secret, so nobody is entirely familiar with this product’s ingredients. However, most WD-40 cans contain a general ingredient list, which gives us at least some insight into what this product is all about.
Knowing the main ingredients will help determine if WD-40 is toxic and how it affects our health.
This ingredient of WD-40 represents hydrocarbons based on C-chain atoms, commonly known as petroleum distillates.
Most organizations, including CDC, ECHA, and GHS, classify these chemicals as toxins that can jeopardize your health.

Is WD-40 Toxic?
As WD-40 manufacturers do not disclose their formula, we can’t determine how toxic WD-40 truly is. However, looking at the known ingredients, it’s undeniable that WD-40 contains some toxic chemicals and can severely harm your health.
WD-40 has flammable properties and can cause a lot of different health issues, depending on the contact between you and this product.
The precise level of risk when using WD-40 varies per ingredient, and their precise concentration remains unknown, as it’s a carefully guarded secret of WD-40 manufacturers.
Because of its toxicity, it’s important to keep WD-40 away from children to prevent them from getting in contact with the chemicals inside.
Is WD-40 Toxic To Pets?
The chemicals inside WD-40 are as toxic to pets as to humans. While your kitty or dog won’t experience any problems if they lick WD-40 once, continued ingestion or inhalation could cause severe health damage to your pet.
You need to remember that animals don’t have a way of judging if something is harmful to them, so they’ll likely taste, lick or touch anything they find nearby. That said, you should keep WD-40 away from your pets to prevent possible issues.
Suitable Alternatives For WD-40
Luckily, there are a lot of suitable alternatives that are better for you while still being as efficient as WD-40. If you’re looking for a substitute for WD-40, you should consider using:
Most people keep some cooking oil in their home, from olive and coconut to other vegetable oils. They are essential for cooking, but they can also come in handy when you have things squeaking around your home.
All you need to do is apply the oil onto a cotton swab or a paper towel and apply it to the affected area. The oil will lubricate the area, eliminating the squeaking and squealing sounds.
If you have a cooking spray in your home, you can also use it for fixing things in your home instead of just cooking. As cooking sprays are made of oil, they can quickly lubricate any area, and, since they are in a spray can, they are easy to use, which is convenient.
Also, if your children or pets get in contact with cooking oil, you won’t have to worry about possible issues as it’s harmless to our health.
There are a lot of different companies that produce plant-based and food-grade lubricants, which are equally effective as WD-40, if not even better. They are safer to use and won’t cause any harm to you or the environment.
Most use petroleum jelly for medical purposes, especially on cracked, dry skin, as it has moisturizing properties. However, petroleum jelly can also act as an excellent lubricant, which is why it can be a great substitute for WD-40.
It’s not uncommon for people to experience various squeaks around their households. However, while many believe they instantly need lubrication, a good wash is sometimes enough to stop the annoying sounds.
Occasionally, things can get squeak or squeal simply because they’re dirty, so that’s where dish soap comes in handy. You can use it with lukewarm water to wash the affected area. Typically, if the dirt is the only problem causing the sounds, this wash will entirely eliminate them.
Although there’s no way to find out the exact ingredients of WD-40, one thing is for sure—WD-40 is potentially harmful to you. If you’re someone who uses WD-40 for various things around your home, it goes without saying that you should take all necessary safety precautions and be very careful while using it.
