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.

A must have in your garage
[This review was collected as part of a promotion.] This product broke through the layers of rust quickly. It sprayed out in a pinpoint stream allowing me to get the product exactly where I needed it to. It does have a strong odor, so make sure you are using in a well ventilated area. You can use some degreasers and hot water to clean up any mess you might of made. Just know it will leave a greasy residue because this is supposed to be a long lasting lubricant. I will always recommend PB Blaste...

Solved by problem, but difficult to control spray
Would RecommendI had a bolt stuck in a 15 year old chair. After about 10 minutes this helped me unstick the bolts. I did find it difficult to spray and although adjustable I always got a bit too much sprayed out. However, it worked well.

Works well!
[This review was collected as part of a promotion.] 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!

Durable, dependable, gets the job done and a great
[This review was collected as part of a promotion.] 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 t...
