B'laster 11 oz. PB Penetrating Catalyst Nut and Bolt Buster

I use this product all the time. From working on vehicles or equipment, and even around the house for sticky doorknob and latches. Love it and always keep a can or 2 handy.

Worked better than I expected on some rusted bolts I couldn't budge. I sprayed it on, let it sit for a few minutes, and they came loose with much less effort. The smell is strong, so I recommend using it in a well-ventilated area.

I recently used the PB B’laster Penetrant, and it’s easily one of the most useful products to have in the garage. It works really well for loosening stubborn nuts, bolts, and rusted parts, but what impressed me most is the design of the nozzle system. I really like the dual-nozzle setup. The longer nozzle gives me finer control and makes it much easier to reach tight or awkward spots without spraying everywhere. Then, when I need more coverage, the regular nozzle is perfect for dousing a nut or bolt with a heavier amount of penetrant. That flexibility makes the product feel much more practical than a standard spray can. The volume control feature is another standout. Honestly, it’s an innovation I haven’t really seen before, and I love it. Being able to control how much product comes out gives me better precision, helps reduce waste, and should make the can last longer over time. Overall, PB B’laster already has a strong reputation, but this design makes it even better. It’s effective, easy to control, and very well thought out.

This stuff works very well and fast. As soon as I sprayed it on the rust came right off. Though I don’t have any rusted parts right now I found some rusted screws on my truck to try it with.
