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.

Great for plumbing use
Would RecommendI love this stuff. I'm usually a WD-40 guy, but I had to remove a bathtub drain that hadn't been removed in who knows how long and it wouldn't budge. I blasted it with PB, let it soak for 30 minutes, then went back and the drain twisted off. I've found my new "unstuck" product.
