Frequently Asked Questions
How does Kroil Original Penetrant work?
Kroil's Aerokroil formula is designed to actively attack rust and carbon deposits at a molecular level, enabling it to penetrate microscopic crevices and break the bond between corroded metal surfaces. This allows seized parts to be loosened and removed.
What makes Kroil different from other penetrating oils?
Kroil's unique Aerokroil formula provides superior capillary action, allowing it to penetrate tighter spaces and more aggressively break down rust and corrosion than many standard lubricants or penetrants. Its ability to work from any angle is also a key differentiator.
Can Kroil be used on all types of metal parts?
Yes, Kroil Original Penetrant is effective on a wide range of ferrous and non-ferrous metal parts, including steel, aluminum, brass, and more, making it suitable for various marine hardware and components. However, always test on an inconspicuous area if concerned about specific finishes.
What is the SprayTech™ nozzle for?
The SprayTech™ nozzle is engineered to allow for precise application of the penetrant from any orientation, including upside down. This feature is critical for accessing and treating components in tight or difficult-to-reach areas common on boats.
What is the NSF H2 registration for Kroil?
The NSF H2 registration signifies that Kroil Original Penetrant (for 8oz and gallons) is recognized as safe for use in certain industrial applications where incidental food contact is not expected. While this is primarily for food processing, it indicates a level of product purity and adherence to safety standards.
