Is Kroil Original Penetrant safe for all types of metal?
Kroil Original Penetrant is formulated to be safe for use on most metals, including steel, aluminum, brass, and copper commonly found in marine applications. Its primary action is to break down rust and corrosion without causing damage to the base metal itself, making it ideal for a wide range of boat components.
Frequently Asked Questions
What makes Kroil Original Penetrant effective at loosening frozen metal parts?
Kroil's effectiveness stems from its unique Aerokroil formula, which possesses an exceptionally low surface tension. This allows it to migrate into the smallest microscopic openings, displacing rust and corrosion, and breaking the molecular bond between mating metal surfaces that causes them to seize.
Can Kroil Original Penetrant be used on marine applications?
Absolutely. Kroil Original Penetrant is widely used and highly recommended for marine applications. Its ability to combat saltwater-induced corrosion, rust, and seized fasteners on engines, hardware, and structural components makes it indispensable for boat maintenance.
How does Kroil Original Penetrant work to remove rust and carbon deposits?
The Aerokroil formula actively attacks the chemical bonds within rust (iron oxide) and carbon deposits. It infiltrates these layers, loosening their adherence to the base metal, allowing them to be more easily brushed or wiped away, or for the underlying parts to be separated.
What is the difference between Kroil Original Penetrant liquid and aerosol formulas?
The core Aerokroil formula is consistent between the liquid and aerosol versions. The aerosol format provides convenient application, allowing for precise spraying into tight areas, while the liquid can be useful for soaking larger components or for bulk application.
What is the NSF registration for Kroil Original Penetrant?
Kroil Original Penetrant is NSF Nonfood Compounds Program Listed, Category Code: H2, with Registration #165745. This registration is specifically for the 8oz and gallon sizes, indicating suitability for applications where incidental contact with food is not a concern.
