PB Blaster vs Liquid Wrench: Which One’s Best?
In this review, we are taking a look at two enduring and highly effective products that have been a stable in DIY toolkits for decades—PB Blaster and Liquid Wrench.
The chances are, you’ve already got a can or two of one these penetrating oils somewhere in your home or garage. Both are lightweight petroleum oils designed to wick their way into the threads of fasteners and provide lubrication. Whether you’re trying to loosen a rusty bolt that is locked in place, separate a seized garden fitting or free-up just about any other metal-on-metal item, you’re going to want one of these oils.
In terms of the effectiveness, there’s not much difference between them. PB blaster is perhaps a little better at penetrating deep into rusted parts, and in that regard may the better of the two. But, it does have an overpowering smell, and if you need a product that you can use inside, you might prefer Liquid Wrench as its odor is much less offensive.
From a price and popularity perspective, PB Blaster is more popular and generally outsells Liquid Wrench, despite being a little more expensive. But to be fair, there’s not too much difference between them in price, and on any given day you may be able to find one on sale and cheaper than the other.
Of course, you don’t have to choose; you could just buy one of each.

The negative reviews about this product tend to focus on its ineffectiveness, at unlocking nuts, bolts and other items that have quite extensive rusting. The consensus of many users is that if you when you have a really tough job, Liquid Wrench just won’t get the job done.
There are also a few negative reviews about cans of Liquid Wrench losing their charge before being empty. However, this appears to be less of a concern than with users of PB Blaster, and users have also made a few comments about Liquid Wrench being quite messy.
Picking a clear winner was quite difficult in this review as both products have been around for a long time, they are both tried and tested over many years, and they both work well.
The main points of difference between the two products being:
- PB Blaster is more effective when it comes to those tough jobs where nuts and bolts are heavily rusted, and
- Liquid Wrench smells much less offensive than PB Blaster and is the better choice if you’re working indoors or in an area with poor ventilation.
All things considered, though, despite its smell, PB Blaster is the more reliable of the two products when it comes to getting the job done. It performs best in the toughest of situations. On that basis, our winning product is PB Blaster.
