What Customers Are Saying
Customers overwhelmingly praise this penetrating oil as the best available for loosening seized and rusted bolts, parts, and hardware. Many report outstanding results on automotive components, lawn mowers, and locks—often within minutes or after overnight soaking—and describe it as outperforming alternatives. Reviewers emphasize it works where other products fail and stress they keep multiple cans on hand as a trusted staple. Some note issues with can pressure loss or defective spray nozzles, and a few mention strong odor requiring ventilation. Despite these minor packaging concerns, most customers plan to repurchase and consider it an essential toolbox item.

[This review was collected as part of a promotion.] It works very well to remove screws that are very stuck and full of star. It works perfectly for any rusted or frozen part and also protects against further rust and corrision.

The straw feature is not good
I think I bought the 11 oz can of PB BLAST with the straw a few months ago or in the spring. Tried using is both ways and nothing comes out even though the can is almost full. I spent money on garbage.

Works great
[This review was collected as part of a promotion.] PB Blaster Penetrating Catalyst is one of the most effective rust-busting sprays out there. It quickly breaks down corrosion and frees up rusted nuts, bolts, and other metal parts. The formula penetrates deep and starts working fast—great for automotive, home, or industrial use. It does have a strong odor, but the performance more than makes up for it. A reliable go-to for any mechanic or DIYer dealing with stubborn metal parts
