Corrosion Block 20004 Liquid Corrosion Inhibitor 4 Liter Refill Bottle

Corrosion Block 20004 is a professional-grade liquid corrosion inhibitor in a 4-liter (approximately 1 gallon) refill bottle. This advanced formula actively protects metal and electronics using polar bonding chemistry that penetrates deep into corrosion cells, displaces salt water, and leaves a hydrophobic protective film. Non-hazmat, non-flammable, and non-toxic, making it safe for use in sensitive environments.

Key Features:

• Advanced polar bonding chemistry kills corrosion on contact
• Completely penetrates corrosion cells and displaces salt water which then evaporates
• Leaves a clean, clear hydrophobic film that acts as an "OFF SWITCH" for corrosion
• Non-toxic, non-flammable, and non-hazmat formula safe for marine, industrial, and automotive use
• Deeply penetrates joints, connectors, and fasteners for comprehensive protection
• Effective on submerged equipment and components exposed to high moisture environments
• Trusted in safety-critical applications: mining, power stations, refineries, and fuel depots

Protects:

• Electrical connections, switches, and circuit breakers
• Battery terminals, alternator leads, and fuse panels
• Electronics, GPS systems, and terminal strips
• Running lights, connectors, and pressure gauges
• Motor operated valves and fuel tanks
• Engines, wheels, hubs, and mechanical components
• Locks and exposed metal surfaces

Unlike waxy competitors, Corrosion Block won't leave sticky residue while providing superior long-term protection against salt water, humidity, and environmental corrosion. Ideal for marine, RV, industrial, and automotive applications where reliable corrosion protection is essential.
