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.

Excellent for RV use
I was having trouble opening my RV's black tank valve to empty it. I tried the other spray. Didn't work. Tried this and it worked! My only criticism is the spray doesn't work consistently. It was very hard to get the straw in the right position for the spray to work or to even press the button to get it to spray. Might it be a defective can? Maybe.

PB Blaster exceeded expectations after a few applications, outperforming other penetrating oils.
[This review was collected as part of a promotion.] PB Blaster worked way better than I expected. I used it on a siezed door jam roller, and after letting it soak and spray a couple times it started to move freely. I've used multiple different penetrating sprays and none have ever worked. The spray nozzle makes it easy to apply exactly where needed, and the smell isn't as overpowering as some other penetrating oils I've tried. Definitely recommended for everyone to have a can of this in their ga...

It gets the job done.
[This review was collected as part of a promotion.] I received this product in return for my honest feedback an I got to say this thing works better than wd40 and since I work in a powdercoating shop is a plus that it's silicone free I strongly recommend this product to anyone.

Works like magic in as little as 30 minutes
[This review was collected as part of a promotion.] This penetrating oil works miracles. Just a bit of it goes a long way. Spray a little on a rusted bolt and watch it eat at the rust. The best part is, in most cases 30 minutes is all that is needed. The included straw easily folds down and stays in place, no longer going missing after the first use.
