WD40 Penetrating Oil

To this day, WD40 remains the most versatile, multi-purpose lubricant on the market. Another thing that has helped increase the popularity of this product is that it is easy to use, even for beginners.

It not only efficiently removes impurities but also provides preventive services against rust and corrosion. It can also help you alleviate the damaging effects of moisture on metal surfaces.

PB Blaster vs WD-40 Comparison

In this case the comparison between PB Blaster VS WD40 can help you to choose the best between the two. So, check out this comparison and pick the suitable one for you.


In terms of versatility, we’d rank WD40 as the superior agent. WD40 solutions are specially designed to meet multiple needs at different levels. This is a feature you will find conspicuously missing in the PB Blaster.

With WD40, you get different solutions with different ingredients. These different versions of this product come in rust release penetrant sprays, water-resistant silicones, long-term corrosion inhibitors and protective white lithium greases, and more, all of which are finely formulated to last longer. Penetrating oil.

However, when you use PB Blaster, you are limited to only three options; Penetrant, corrosion stop, and multi-purpose lubricant.

While this is obviously not in favor of PB blasters, they compensate for the lack of versatility by giving you an overall stronger effect.

Efficiency at Eliminating Rust

While both WD40 and PB Blaster can be used to remove and prevent rust, PB Blaster has a slight edge in this category.

PB Blaster’s high-quality oil-based formula means it’s a superior product for covering all small gaps, nooks and crannies, while simultaneously removing rust and dirt.

WD40’s water-based formula uses anti-corrosion properties but customers all agree that PB Blaster is the strongest product, providing the best results.

Both WD40 and PB Blaster work well at removing and preventing further rust in the future, but PB Blaster gives you a little more bang for your buck.

Raw Power

When it comes to brass tacks, everyone wants a penetrating oil strong enough to protect the surfaces they’re applied to.

There is no disputing that both of these oils are quite powerful. WD40 is considered by several experts to be one of the first-grade penetrating oils. All this said though, it cannot match the overwhelming power and capabilities of the PB Blaster.

Thanks to the combination of high-quality corrosion removal properties in the PB blaster, it removes grime, dirt and other unwanted particles with greater accuracy and precision.

Again, that’s not to say that WD40 isn’t a great agent either. However, PB Blaster may be able to get you a lot more with less effort.


PB Blaster can beat any penetrating oil in terms of performance and quality. Both products are made from the finest raw materials and have a truly spectacular blend of ingredients. That being said, perhaps PB Blaster is oil-based and WD40 doesn’t give the former an edge here.

This is because the PB Blaster readily and easily slips into various nooks and crannies, cleaning spotless in the process. The fact that it can easily access those hard-to-reach places also adds to the product’s level of efficiency.

Safety Facts

Both WD40 and PB blaster are very safe to use when properly applied and appropriate protective equipment is worn. However, more potentially harmful chemicals are used in the manufacture of PB blasters.

Since it is water-based rather than oil-based, WD40 can be argued to be the safer option of the two. Customer reviews regularly mention a strong smoke smell when PB Blaster is used on certain materials.

Whenever you use any of these products, first read the instructions on the can thoroughly and keep them out of the reach and sight of children.


Price wise, you should know that you have to pay a bit extra to get the PB blaster. On the other hand, WD40 is not only less expensive than PB Blaster, it is also more affordable than many other penetrating oils.

So, if you’re on a bit of a budget, you can use WD40 and still be confident that you’re using a really great product.
