WD40 Alternative Options With Expert Review

WD40 is a popular brand of multipurpose lubricant that reduces friction and wear on metal tools, but it is also known to stain and damage some surfaces. It’s a household name for squeaky hinges, squeaky doors, and more. Despite that reputation for household tasks, however, WD40 does have its limitations, namely in high-performance environments.

Those with lubrication needs beyond what WD40 can handle may want to explore other options instead.

Here Are a Few WD40 Alternatives to Better Meet Your Specific Requirements

1) Silicone Spray

Silicone spray is beneficial for most types of equipment, including door hinges, locks, and window handles. This type of lubricant also works well on the small moving parts of equipment that are hard to reach with a rag or brush. The real benefit of silicone spray is its ability to protect against corrosion and moisture buildup. Water-based lubricants like WD40 lose effectiveness over time because water molecules easily displace them during use.

Because silicone cannot be displaced by water, it’s one of the best alternatives for preventing rust in places like bathroom and kitchen sinks, as well as areas where there’s constant exposure to water. In addition, it’s considered an effective lubricant for athletic trainers because of its ability to lubricate the skin while also supplementing the natural oils found in the skin.

2) Molybdenum Disulfide

While WD40 was originally intended for use on heavily rusted equipment, Molybdenum Disulfide (MoS2) is primarily a lubricant. MoS2 can displace water from metal swells and free up areas of friction due to oxidation. MoS2 can last for up to 10,000 hours of use in this capacity and does not produce residues as WD40 does. Manufacturers such as MSC Industrial Supply offer MoS2 in spray and paste form. This material is also used in nanotechnology and semiconductor manufacturing processes.

3) Silicone Grease

Silicone grease is one of the most widely used WD40 alternatives. According to an article published by Mechanical Engineering Magazine, silicone grease is superior to WD40 for engineering uses and won’t leave a messy residue on sensitive equipment. This is because that lubrication from silicone grease lasts longer than WD40 and has a higher viscosity. It’s commonly used as a lubricant for all sorts of machinery and equipment.

It’s also very beneficial for greasing axles and bearings in gears, wheels, and other areas where there’s a lot of friction. Because it can last up to six months at a time, it’s ideal for maintaining machinery that’s left unused in storage. Once applied, silicone grease keeps working on the same area until removed or replaced with a fresh application.

4) Hydraulic Oils

Using hydraulic oil instead of WD40 has been said to produce better results, but that concept is debatable. According to some sources, hydraulic oil’s main benefit over WD40 lies in its ability to penetrate crevices. This can be particularly effective in parts of machines where WD40 cannot reach.

5) Petroleum Jelly

Petroleum jelly is another household WD40 alternative. This material has a lower surface tension than water, allowing it to fill gaps and displace moisture from areas of friction caused by oxidation or rust. This can lead to an improvement in equipment performance and longevity.

Professional advice is to use petroleum jelly at room temperature for best results, as it works better when not warmed up. Petroleum jelly also reduces friction and improves corrosion protection, making it an ideal material for applications ranging from jet engine components to metalworking tools and other mechanisms that are susceptible to wear over time.

6) Liquid Wrench

A liquid wrench is a high-viscosity industrial lubricant designed specifically for use in applications such as machinery, machine tools, and automotive components. Its viscosity increases with applied pressure to a level that no other known solution can surpass. Its ability to “bite” into its intended application makes it an ideal material to use for extremely tight spaces where there is no other option but a screwdriver. It’s highly recommended to repair cars as an alternative to WD40 because of its low toxicity. While WD-40 can contain harmful chemicals, the liquid wrench is completely safe.

7) Vaseline®

This product is commonly known as petroleum jelly, but WD40’s main ingredient is Vaseline petroleum jelly. This oil-based lubricant also provides a silicon compound to help lock in joints, but it also has a higher melting point so that it locks in joints better and prevents them from damaging themselves through wear and friction. It’s especially beneficial for those who need their equipment to function correctly under extreme circumstances, such as in the military or with extremely heavy loads.

8) Liquid Metal

An industrial lubricant based on nitromethane, liquid metal is a low-viscosity lubricant that repels water and most chemicals. It’s said to have been used in the space program for use on small machinery and other areas where extreme conditions are required. Because it’s not considered an explosive or flammable material, liquids designed for use in the preparation of explosives are prohibited from using liquid metal. Most small engines and power tools use a non-flammable alternative to WD40 called Kroil.

9) Dry Lube

This dry powder provides a layer of lubrication in high-performance machinery and equipment. It’s infused with an oil-based lubricant to keep friction and wear to a minimum. This material can last several times longer than WD40, especially in ball bearings and drilling equipment applications.

Liquid lube is one of the most effective alternatives to WD40 because it can be applied directly to surfaces in need. The powder is sprinkled over the area, rubbed into slippery surfaces, and then brushed off with a brush or rag before use. This process reduces buildup over time while leaving no oily residue on surrounding parts or equipment.

10) Mineral Oil

Mineral oil is another option for DIYers looking for a simple, affordable alternative to WD40. It also has a low toxicity rating because of its high resistance to water and rust, making it a desirable alternative for medical equipment such as stethoscopes and surgical tools. Mineral oil can also be easily applied to metal surfaces, but it can build over time. For this reason, mineral oil should only be used on small parts that need a smudge-free prime. Mineral oil can also be used as a heat transfer agent, particularly in contacts exposed to high temperatures.

11) Sticky Stuff

The sticky stuff is a silicone-based lubricant designed to keep small pieces of machinery and equipment from getting stuck together. This is especially useful for applications where constant movement is necessary. Its formulation allows the liquid to form an impenetrable layer over the surface while resisting water and most chemicals. One downside to sticky stuff is that it’s only meant for small moving parts, like the hinge on an appliance or door. It should not be used for large pieces of equipment because it can lead to clogs or blockages within the machinery itself.

12) Wollastonite

An alternative to WD40, wollastonite is a natural mineral from the earth. It’s described as an “inorganic mineral” because it’s not technically real “oil,” but it can provide lubricant qualities similar to those provided by WD40 without the harmful chemicals. It works best on machines and equipment exposed to extreme heat, such as in the automotive or aircraft industries. One downside is that it’s doesn’t last as long as WD40, so it should be regularly reapplied after several hours of use.

WD40 Alternatives

Can I Use Vegetable Oil Instead of WD40?

The short answer is yes, but we recommend against it.

We would not recommend using any type of vegetable oil instead of WD40. Vegetable oils, such as canola or olive oil, will eventually break down and form a thick gooey film over the metal and can inhibit the WD40 from providing its lubricating properties to your project. We would suggest using WD40 brand spray lubricant.

If you do use WD40, make sure to wipe off any excess. Excess WD40 will form a thicker coating, which can inhibit proper movement and prevent the proper function of the moving parts. In addition, spray the lubricant on a clean cloth and then wipe it on the metal surface. This will provide lubrication without leaving a messy film that could attract dirt and dust or even cause rust. If you are not sure if you have applied enough WD40 to your project, apply a little more to be on the safe side.

Can I Use Coconut Oil Instead of WD40?

The short answer is yes; you probably know plenty of things you can do with coconut oil. It’s a staple ingredient for many people’s diets and beauty regimens. But did you also know you could use it as a lubricant? Coconut oil is safe to use on just about anything that requires some form of greasing up. So next time your bicycle chain gets all rusty, or your snowboard won’t glide smoothly over the snow, don’t worry about buying expensive lubricants. Just whip out the coconut oil, and you’re ready to go.

Another great thing about this stuff is that you can use it for just about any lubrication situation, from your car engine to your prop plane. It’s safe to use with food and works well with waterproofing materials and medical equipment. It’s also great for glass and metal. Spread some on and wipe it off with a dry cloth. If you haven’t heard of this stuff before, then you might not be aware of all the things you can do with it.

How Do You Make Homemade WD40?

We will show you how to make a popular lubricant from scratch: WD40. This versatile product’s formula is very simple, consisting of just four ingredients: kerosene, liquid soap, and volatile oil.

While this recipe is quite simple, it does come with a few warnings and considerations. These tips will make the process easier and ensure that you create a safe and effective product. First, never use a metal container when mixing the ingredients for your homemade WD40. Instead, use a plastic or glass container (such as a large juice jug) for storage. The metal reacts with the contents of the spray, causing corrosion and premature wear on your tools and equipment.

Second, make sure that your oil is not rancid. Rancid oil can cause harm to your skin and lungs when inhaled over time. Keep the oil tightly sealed and away from direct sunlight or heating sources to avoid these problems.

Lastly, do not mix the kerosene and jet fuel with your homemade WD40. The two can create a powerful flamethrower that could melt through the foil or even your skin when mixed. Such an accident is far worse than any infection you might get working with the product! Remember also that diesel fuel may also react with this formula.


– 2.5 oz. kerosene

– 1/10 oz. Lubriplate or Lysoform soap

– 1/10 oz. synthetic motor oil


Start by pouring the kerosene into a clean plastic or glass container. Make sure that the container is no more than 2/3 full to help with mixing later. Add the soap and the oil drop by drop while constantly stirring with a glass stirring rod or wooden dowel. After several minutes of gentle stirring, the mixture should resemble a loose paste should not be runny enough to drizzle out of your container.

Once the mixture looks like a paste, make sure to place it in a dark, cool place for maximum shelf life like the rest of the ingredients. Repeat this process until the desired strength is reached by adding more soap and oil.

The resulting product will be a thick liquid that can be used on metal and plastic surfaces. You can cover exposed nuts or bolts with this stuff to keep them from rusting (provided you are careful not to get any of it on yourself). The oil may also be applied directly to metal surfaces in order to lubricate them and prevent further rusting. It can even be sprayed on tools and equipment to keep them running more effectively. WD40 can even be used to clean fencing to prevent sweet dreams from turning into nightmares.

This formula is especially useful for removing rust from metal or plastic items or keeping equipment running smoothly and efficiently. Use it on tools and electrical devices to keep them running smoothly, apply it to your bike chain to keep it free of sand and grit. While you may pay a bit more for premade WD40 in a store, you will find that making your own is much cheaper and just as effective as the original. Have fun and keep things safe out there with your WD40 alternatives!
