Scaling Penetrating Oil VS WD40 Oil’s Rust & Corrosion Strength

To protect your metal surfaces from rust and corrosion, you need to be careful with harmful elements. It’s even tough to select better oil to prevent metal rust. Here we try to make a discussion on Penetrating Oil VS WD40 to get clear views.

The main difference between Penetrating and WD-40 oil is their viscosity range. Penetrating oil is known as penetrating fluid and can penetrate the tiny surface between the threads of two joints. However, WD-40 is specially made for displacing moisturizers and lubricants, protecting corrosion and rust-free and penetrating internal stuck parts.

In the vehicle engine components, oil would be more effective in reducing friction and increasing mileage. So to learn more about Penetrating oil and WD40, continue your scrolling.

Penetrating Oil Is What?

Penetrating oil is specially made to clean rust with smooth flow and reach every particular thread component. For its low viscosity, it can gently flow on all metal surfaces smoothly and easily can cover the scratch or damage. If there is a rust or corrosion layer, it will also be responsible for removing it from metal surfaces and protecting air and water oxidation for a long time. Let’s check its chemical elements.

Chemical Elements

Penetrating oil is introduced with a proper combination of different chemical components. Here included those chemical objects which are eligible to make a shield against the rust and corrosion inhibitors.

  • Methyl Silicone Paraffin
  • Lower Alkyl Benzenes
  • Zinc Dialkyldithiophosphate
  • Test-di butyl-p-cresol
  • Poly Methacrylate
  • Blend of lower Alkanols
  • Alkyl Succinic acid

 

WD-40 Oil Is What?

WD-40 is lubricant oil, not like penetrating oil. The primary formulation of WD-40 oil was developed by Rocket Chemicals before 1953 and produced as commercial lubricant oil in 1961. It displaces the water and destroys the chemical reaction or oxidation to protect from rust and corrosion like PB Blaster.

 

Chemical Elements

In WD-40, these chemical elements are responsible for protecting water reaction with air. It creates a barrier to oxidizing and smoothly cleans all liquid wrench rust and corrosion quickly.

  • Hydrode-Sulfurized (Xylene, Mixed Isomers, 1,2,4-trimethyl benzene, 1,3,5-trimethyl benzene,)
  • Hydrotreated Heavy
  • 2-4% Carbon Dioxide
  • 25% Petroleum base oils
  • 50-60% Naphtha (Petroleum)

 

Key Differences Between Penetrating Oil & WD40

After focusing on the main points of both oil, we also get a view on Penetrating and WD-40 oil. To learn in detail, we need to focus on their specific criteria. Let’s check the following points carefully.

Nature

Penetrating nature is a fully penetrating lubricant and easily can reach internal components smoothly. It will be adequate to perform on tiny surfaces that are not easy to get and clean. But this oil can flow gently in narrow spaces quickly.

However, the nature of WD-40 is not penetrating. Though most people know it’s penetrating oil, it’s a wrong concept. You can say it’s the upgraded version of lubricant oil and the mother formulation is the same.

Performing Area

Generally, the best penetrating oil can perform in long distances, such as cables, gear, casters, electronic terminals, bushing, air tools, etc. So, according to your need, you can easily use a penetrating catalyst on almost all types of metal surfaces.

Wherever the WD 40 specialist penetrant can also perform in various metal objects, there is some restriction to use here. It’s not perfect to use locks, iPods or iPads, door hinges, paintball guns, and bike chains. Otherwise, you can spray this oil on other metal surfaces for rust prevention.

Extra Pressure Additives

In Penetrating oil, you get suitable additives with extra pressure, responsible for making a thin coating on metal surfaces. That will protect all harmful elements from scratch and deep holes in any road conditions.

On the other hand, WD-40 offers better additives with the extra pressure that is useful to make your metal scratch-free if a deep hole or damage can easily cover the whole damage area smoothly.

Rust & Corrosion Protection

There is a chance of creating a chemical reaction when driving for a long time in all weather, especially in the rainy season. This oil will protect all types of rust and corrosion for a long time without coating frequently penetrating oil.

However, the WD-40 lubricants oil stands for Water Displacer; that’s why it seals the water entry into internal metal components. As a result, water can’t be oxidized with air, and your metal base, spark plugs, stuck nut, bearings, hinge, or rusty bolt will keep bright and stable for a long time and continue the water displacement process.

Viscosity

The best penetrating oil is low-viscosity oil. For that reason, it can reach every internal joint smoothly and clean all rust and germs. This Kano Aerokroil penetrating oil will perform better than the other oil for the deep rusted parts.

Wherever the WD-40 lubricants oil is high viscosity oil, and for quick remover rusted bolt, it plays an influential role. In any condition, when you need to clean all rust within a short time and the layer would thin, WD-4o oil performs better in that condition than mineral oil.

Recommendation

After completing an extensive discussion, now we reach to take our final decision. Both are genetically the same, and the formulation process and chemical components are closely related. The lubrication is responsible for doing its duty to make your metal bumper and other parts and nuts from corrosion and rust. They protect water and air oxidation in all weather and protect all outside harmful elements.

So if you want to clean between two internal threads smoothly, then Penetration oil will perform like marvel mystery oil. But if you’re going to get a quick solution of the bolt and rusted nut with silicone spray, then WD-40 will be the best option. But for better performance, flexible price, and specific area of use, we suggest you use Penetrating oil.

People Often Ask

What Are The Substitutes Of WD-40?

You can take Short Penetrating Dry Lubricant as the substitute for WD-40 for better performance. Its plumber grease, beeswax, petroleum jelly, non-toxic, non-flammable, and 100% biodegradable, can easily match any metal surface or related products.

Can WD-40 be Used As Penetrating Oil?

Yes, you can use WD-40 as kano Kroil penetrating oil. Though there are differences, their production formulation and purpose are the same. Its cost is lower than the other penetrating oil and introduced with acetone vegetable oil. So there are no problems with using WD-40 as penetrating oil.

Does Penetrating Fluid Actually Work?

Cleaning with penetrating lubricants is a breeze. A wide variety of substances may be removed from surfaces with these products. This is due to the fluid’s versatility as a cleaning or degreasing solvent.

How Long Perform WD-40 In Metal Parts?

The answer is up to 1 year for outdoors and two years for indoor use. To protect against rust and block corrosion, WD-40 is specially designed for the seized bolt. Some practical chemical elements are responsible for creating a shield against all chemical reactions.

Final Thoughts

Hopefully, you get a clear concept of Penetrating Oil VS WD40 with their specific working area. Both are introduced to keep your metal objects clean from rust and corrosion. According to your actual need, you can easily choose any of them because their formulation and purpose are about the same.

If you want a smooth clean between two thread parts, Penetrating oil can be the best option. But for a quick clean, and natural segment, WD-40 will be the best option. So the choice is yours and hopefully enjoy a lot with any of them.

If you still have any confusion, reread the content carefully. You even can get suggestions from an expert or oil producer to reach the final decision.
