Penetrates Quickly Attacks Corrosion Helps Remove Rust and Carbon Deposits Simplifies Repairs Quickly Loosens Rusted Nuts and Bolts Loosen frozen metal parts the professional way, with Kroil Original Penetrant in liquid and aerosol (formerly AeroKroil) formulas. Discover why Kroil has been trusted to help loosen bolts in various applications since 1939. Rusted Bolts Rusted Metal Bike Chains Motorcycle Chains Garage Door Rollers Door Hinges Moving Parts Quickly Penetrates Threads and Crevices Tight spaces are no problem, because Kroil penetrates threads or crevices to break down rust and unstick seized bolts. So, whether you’re lubricating dirt bike motorcycle chains, rusty old door hinges, or stubborn garage door rollers, Kroil isn’t afraid to get in tight spots and get dirty. Magnifies Muscle When tackling the toughest nuts and bolts, any additional leverage helps. Kroil loosens tough rusted parts quickly, requiring less torque to loosen. Now that’s leverage! Corrosion meets its match, as Kroil removes and prevents rust, cleans carbon deposits and lubricates rusty parts. Breaks Down Carbon Deposits Kroil not only breaks down rust, but also carbon deposits and other buildup that can seize metal parts. Review: Better than peanut butter - I first started using this stuff in the Air Force. In my opinion it saturates seized but and bolt threads better than most every other penetrant. I spray every nut and bolt before I ever put a wrench on it. Let it sit and watch it get drawn in the threads. I’ve not broken a bolt in years and I work on some really old stuff now. Easy to use, a little bit goes a long way. Review: Kroil penetrating spray - Very effective. Gunsmith recommended.
