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.

Works great hard bolts, nuts
Would RecommendWhere has this been my whole life?! It's been a huge help to break lose tough bolts way better than WD40. Just remember, WD40 is a lubricant, this is not. This is great to help loosen things and it works wonders!

Great for rusty bolts
Would RecommendI bought this product to help loosen rusted bolts on my jeep and it worked like a charm. It does take some time to soak into the threads, so I would recommend spraying and leaving overnight.

Best penetrating product on the market!
[This review was collected as part of a promotion.] Love this product for loosening rust bolts on my older vehicles. It definitely helps by penetrating the parts to aid in removal. Always keep a can (or 2) handy.

Lubricates well
[This review was collected as part of a promotion.] Sprayer works well for loosening and lubricating. Easy to use with either the straw or the wide spray. Spraying with the straw causes a thicker orange foamy spray. The wide spray creates more of a mist. Only draw back is this stuff smells really strong. Make sure to be well ventilated when using. Smell can also linger on your fingers if not wearing gloves.

Great penetrant for loosening hardware!
[This review was collected as part of a promotion.] I used the blaster to loosen some nuts on my air conditioner and see whether it would also remove rust. Mind you, this is a marine air conditioner and it did a fantastic job loosening the nuts. Rust in saltwater is a much tougher task and I suspect there are better products offered by Blaster.
