Kroil is "GOOD STUFF" best penetrant by far
Best penetrating oil on the market by far! I've been using it since the 1960s when it was only available to industry. I'm glad it's readily available to all of us today. It really does lossen frozen fasteners in cars, boat engines, motorcycles, farm equipment, ect. I also works as a firearms bore cleaner when mixed into bore cleaning solvents (25% Kroil/75% Bore solvent.) The Kroil "creeps under metal fouling in the barrel rifling loosing it for easy removal. Kroil is just "Good Stuff"

Incredible stuff
My dad had a can from the time I was small, it was great, the new stuff looks different but seems to work even better. This stuff is great. After spending weeks on a stuck screw, tried everything to no avail. In one night of this the screw came out easly.

They Say Kroil Is Made by Squeezing Leprechauns - I Believe It.
I’ve used a lot of penetrating oils over the years, but Kroil Original really does live up to the legend. I’ve been using it on your run-of-the-mill rusted nuts and bolts, and it works like magic. A few drops, a little patience, and things that should’ve snapped loose years ago finally start moving again. They say Kroil is made by squeezing leprechauns - and after seeing how it creeps into threads and breaks loose rust, I’m starting to believe it. The drip can make it easy to apply precisely where you need it, without wasting half the can in overspray like aerosols. It’s not cheap, but a little goes a long way. If you’re working on anything that’s been sitting in the elements - old cars, farm gear, or just corroded fasteners - this stuff is worth every penny.

Kroil is great stuff
Kroil in its original form. Oil yes. You squirt it or drip it from this easy application can. Best value for the money form. This form lasts longer than aerosol spray. It drips out no noise.

The Pros’ Choice — Forget That Stinky Parts‑Store Stuff
I’ve used Kroil for years in my shop—on rusted chassis bolts, seized hinges, and stubborn suspension parts—and it clears the toughest corrosion better than anything else I’ve tried. It seeps deep into narrow thread crevices, loosens frozen hardware, and leaves parts soft to the turn within minutes. This isn’t a filler or lubricant—it’s purpose-built to break corrosion bonds. The 8 oz drip can delivers precision application, avoiding overspray and ensuring the penetrant goes exactly where it counts (). Mechanics swear by it—even Boeing used it on production floors, according to manufacturer testimonials. I don’t need a fancy pouch to know it works: after 20–30 minutes, the stuck parts almost come apart by hand—no heat, no crowbar. Its smell is industrial and strong, sure, but that’s a small trade for real results on rusted metal. Bottom line: Kroil dissolves my shop’s toughest rust and gives me confidence on every job—from farm rigs to collector cars. It’s worth every penny.

Non capisco la logica di fare arrivare il beccuccio dosatore posizionato in maniera inversa a come dovrebbe essere messo, cioè è messo sotto al tappo anzichè sopra. Prima di riuscire a capire come fare per sistemare, è passato parecchio tempo, davvero macchinoso se non diabolico! mi chiedo ma era così difficile vendere il prodotto con il beccuccio già posizionato nella maniera corretta? a parte questo inconventiente che mi ha irritato non poco, il prodotto è fantastico e fa quello per cui è nato!!
