Kroil Applications


Corrosion, compression, and chemical reactions often cause frozen metal parts to stick together. Short of hitting them with another object, fused metal objects have traditionally been hard to separate. However, with Kano AeroKroil Penetrating Oil, you can save your energy for other projects. It makes its way into the smallest spaces to break the chemical bonds holding two pieces of metal together, whether they're stuck because of thermal variations or electrical relationships.

Kano Kroil Penetrating Oil promptly penetrates so that seized parts move again. Its unique chemical makeup allows it to break down rust, corrosion, and caked-on substances while loosening and lubricating your engine's components. This aerosol can-based oil contains small concentrations of aliphatic alcohol, glycol ether, and trimethyl benzene, so it works hard to break the bonds tough substances create.

Each can of Kano Kroil Aerosol (AeroKroil) Penetrating Oil features a spray nozzle with a long, slender attachment that makes it easy to spray into hard-to-reach areas. It's considered "The Oil That Creeps" because even if you cannot spray it directly on the bond you need to be loosened, AeroKroil makes its way to where it needs to be.
