Lubricate and break free

12 days ago

I’ve been using PB B’laster penetrant at home and at work to break free bolts, nuts contaminated with rust. It’s a must have lubricant that acts quick and easy to use unlike a torch.

Works well!

My back door shifted over the years and needed to remove a screw off of a hinge to readjust it. This spray did the trick! Came out very easily and the product was very easy to apply. Didn’t cause any stains, however, there was a strong chemical odor which I expected. I didn’t need much and let it soak for a few minutes and it worked well. Very happy!

This stuff is a must, saves time, effort, and frus

I used the PB blaster on my trailer to loosen up some old rusted bolts and it worked way better than expected. The spray penetrate deeply into the threads and start breaking down. Rust pretty quickly. I noticed a difference within minutes what I like the most is that it doesn’t just loosen the parts. It also leaves behind a light lubricant that helps protect against future rust, which is perfect for traders exposed to the weather like mine. It’s easy to use and you don’t need instructions and the cleanup easy also. Honestly, a great product in my opinion.

Durable, dependable, gets the job done and a great

The selector on the straw spray feature is a great idea and works very well. Overall the entire cap is very durable and stays on even with force applied or drops unlike other brands I've used. I've been using PB Blaster for years and it is my go to penetrant for stuck bolts, nuts, bearings, pins and all sorts of other components that can seize. It leaves a film after drying to prevent seizing in the future which is a great idea as well. It is the only brand I trust through and through and has always had a competitive price as well as the best bang for your buck.
