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.

Stuck nuts no more
[This review was collected as part of a promotion.] Can't get over how amazing this product is. The smell is like that of wd-40, not un pleasant what so ever. It worked on every project I used it on and I will be recommending it to others.

Smelly and only worked half the time.
Would RecommendI bought this a couple of weeks ago to try to get the shower door screws loose so we could take off the frame. unfortunately it only loosened one of the screws so we still can’t get the frame apart even with extra soaking. I think the problem is the screw is in so deep and flush with the edge it can’t penetrate inside. As it says on the package, you need good ventilation because it smells very bad. It took a couple days for the bad smell to clear from our bathroom.

Great product at an affordable price
[This review was collected as part of a promotion.] This product had an amazing ability to clean up all the residue, and it comes at an amazing value. It is a small bottle which is easy for storage and it has a lot of durability. I’m oppressed with the coverage that this product provides.

Great for rusted bolts and nuts

The PB Catalyst Spray is an absolute savior in a can!!
[This review was collected as part of a promotion.] The B’laster Corporation has done it again with the PB B’laster Penetrant Catalyst Spray! This spray definitely does its job in providing components and hardware with the lubricant needed for fighting rust, corrosion and more. This spray does have a strong odor to it, but its effectiveness is GRADE A! This can will last a long time and it has a safety mechanism that will allow for storing away with no issues. The instructions provide clarity on...
