Review: Wow! Surpasses expectations - Yes, it is crazy expensive. 3-5x the price of the competition. NOT well known. No advertising. Limited availability. But wow. This stuff really works. The hype is real. The drip cap is quirky; don't break it. Used just a few drops on some very heavily rusted parts that had been sitting for 20 years. A few minutes later, they came apart easily. Count me impressed. This 8-ounce can is probably a lifetime supply for most homeowners. Cannot believe this has been around for 80+ years. If you need something that may or may not work and have a thin wallet, buy one of the many choices at the big box store. If you have expensive parts that absolutely need to come apart, pay the price. You will not be disappointed

Whether I’m working on rusted bolts, stuck machinery parts, or even old tools that have been sitting unused for years, this product gets the job done quickly and efficiently. The penetration power of Kroil is unmatched. It seeps into the tiniest cracks and breaks down even the toughest rust and corrosion. In many cases, I’ve been able to loosen parts that I thought were impossible to get unstuck, saving me time and frustration. It works fast, and you don’t have to wait long before you see results. The application is easy, and the spray nozzle gives a controlled, fine mist that ensures the oil gets into the tightest spots without waste. I appreciate how it doesn’t leave a greasy residue after use, making cleanup a breeze.

## Questions & Answers

**Q: Would this product be safe and effective for removing rust from a blued firearm?**
A: It will not harm your blued finish. You would not believe how well this works, it is just amazing.  I used it on firearms with a little bit of rust and cleans things right up with no issues. I also like to plug The end of the barrel filled with Kroil and let it sit overnight 24 hours. I do this after a thorough cleaning of my fire arm and barrel that looks like his perfectly clean. 24 hours after I've soaked the Kroil in the barrel you would not believe the amount of blacks soot/junk that came out after the soaking. Also I have used it on squeaky doors, the door on my Dodge Ram starting to squeak, one application no squeak whatsoever. I swear this stuff must be waterproof.   Even going to use it on my shot on my truck when I replace my shocks to help loosen the bolts.  You will definitely not be disappointed. Definitely buy it, but it, but it.

**Q: I have a bolt that goes through a 5" collar. The bolt and the collar are fused together by rust. Will this product penetrate through the whole 5"?**
A: That's pretty much a see what happens.  To my knowledge this is the best penetrating oil available anywhere. Give it a try.  I would give it about 5 to 10 applications, with a minute or two in between then give it a try. Give it time to work thru. Good luck.

**Q: What is the difference between the Kroil penetrating oil and the lube????  I plan on using either for gun maintenance, which is better??**
A: Use both Kano and a premium gun lube. The Kroil should be used for rust removal and bore maintenance - its amazing how much stuff Kroil will remove from a "clean" bore. It is not an ideal operating lube, being too thin to persevere. It was designed as a cutting and penetrating oil. Really great stuff for lubing drill bits during cutting. Use premium lubes on action friction surfaces. Anything from Microlon, Break Free, or probably a dozen other manufacturers.

**Q: Is this product a good choice for removing rust from a table saw surface? This is a heavy cast iron/steel top surface on a Delta saw.**
A: No.  Not because it won't work but because it won't work any better than other products that are 1/3 the price. I wouldn't use penatrant for rust removal. Either wd40 and steel wool or evaporust or naval jelly.....depending on how bad the rust is

*by D***Y on May 5, 2026*

I wanted to give 4 stars, because this stuff is expensive. This seller is half the price of hardware store tho. This really works on penetrating rust & freeing up stuck parts. I would recommend this seller.
