Buyers’ Guide – PB Blaster VS WD40

So, now that we have taken the time to cover what sets each lubricant apart, let’s look at how you can make the best choice. There are a few things to consider whenever you are planning to buy an industrial lubricant, and these considerations can help you get the best bang for your buck. 


The first thing to consider when buying an industrial lubricant is what you need it for. If you are simply trying to slide a piece of PVC pipe into a tight area, you may not need an exceptionally powerful lubrican at all. However, if you are planning to loosen a rusted bolt or clan your engine parts, you may need something with a bit more ‘kick’. This can help you determine which lubricant might be best for you as WD-40 is not quite as strong as PB Blaster in general.


Next you want to consider how well the product will protect against and prevent future corrosion and rust from occurring. This comes with the hydro-phopic and anti-corrosive properties of the compound. This ensures that you won’t need to use a lubricant if you need to manipulate the part in the future. Luckily, both PB Blaster and WD-40 perform well here!


Safety is always going to be the most important factor for using any industrial compound. You never want to cause any damage to yourself or the components you are working with. Both PB Blaster and WD-40 are safe to come in contact with the skin–they won’t cause any chemical burns. However, WD-40 is generally safer and less irritant than PB Blaster for sensitive skins. It also produces less fumes which can irritate the lungs and eyes. Here WD-40 gets the edge!
