## Description

Product description KROIL ORIGINAL PENETRANT. BEST PENETRATING OIL. Kroil's unique, proprietary molecular architecture creates an affinity to metal that guarantees swift penetration, while maintaining a molecular structure capable of breaking bonds at the first molecular level. This unique molecular architecture was chemically engineered in the laboratory based on research which defined the interdisciplinary physical, electrical, mechanical and chemical properties which cause frozen metal parts. This research enabled Kroil to be chemically engineered to loosen frozen metal parts in every instance regardless of the cause. NOTHING WORKS LIKE KROIL Kroil penetrates into ultra-tight spaces, breaking down rust and corrosion to loosen seized metal parts and linkages. REAL SCIENCE Kroil’s proprietary formulation ensures swift penetration of metal connections, and is capable of breaking corrosive bonds at the first molecular level. FAST. DEPENDABLE. DONE. Use Kroil on nuts, bolts, screws, pulleys, shafts, bearings, bushings, guns, pipe threads, spindles, valve guides, or on any corroded threads or tight parts. SILICONE LUBRICATION Sili Kroil works quickly to loosen and lubricate rusted or corroded metal parts and joints. (Found exclusively in Silikroil products) KEEP TOOLS RUST-FREE Kroil works to keep tools in great condition by fighting corrosion due to heat, salt water, chemical action, or weathering. THE GO-TO PENETRANT Kroil dissolves and removes rust, carbon deposits, gum, dried grease and oil, without attacking metal.

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
Review: It works quickly and you don’t have to wait long to see the results. - I’ve been using Kroil Original Penetrating Oil for a while now, and I can honestly say it’s one of the best penetrating oils I’ve ever used! 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.

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.
