Loosen frozen metal parts the professional way, with Kroil Original Penetrant in liquid and aerosol (formerly AeroKroil) formulas. Based on scientific discoveries at Kano Laboratories, Kroil creeps into millionth-inch spaces, dissolves rust, and lubricates to loosen frozen metal parts easily. Kroil’s unique molecular structure facilitates penetration while maintaining a structure that breaks bonds due to either corrosion or compression.

• Attacks corrosion: Frees bolts, fasteners, and other mechanical components.
• Removes rust and carbon deposits: Will not attack or damage metal.
• Penetrates faster and deeper: Can get into the smallest spaces, threads, and openings.
• Works everywhere: Can be used on any corroded thread or tight parts.
• Simplifies repairs: Makes maintenance jobs easier, faster, and safer to execute.
