A must have!

Always has been a must have in my garage ever since high school small engines class. Can’t count how many times I’ve been saved by PB Blaster. Doesn’t leave the shop messy or stain.

The gold standard for stuck bolts

12 days ago

The B’laster PB penetrating catalyst is easily the most effective tool in my garage for dealing with rusted or seized hardware. Inlike standard lubricants, this truly breaks the surface tension and eats thru the rust, making even the most stubborn bolts manageable. It saved me an immense amount of time and frustration on multiple projects. If you’re doing any kind of mechanical work or maintenance its an absolute necessity to have on the shelf. Well packaged, quick to use, quick drying and minimal noise.

Waiting for the PB Blaster to loosen this frame bolt with corrosion on ot. The smell is not bad and it performed as expected with prior experiences. Consistency is a valuable commodity

Perfect lubricant to help with those stuck fasteners! The new applicator nozzle is incredible, no more over spray, no more wasted product. I love the ability to gently apply to the areas I need rather than just soak everything for no reason.
