Zep 45 Dual Force Penetrant & Lubricant — 14 oz Aerosol, Dual Spray for Rust Loosening and Corrosion Protection

Zep 45 Dual Force is a 14-ounce penetrating lubricant that loosens rusted parts, displaces moisture and provides lasting corrosion protection.

Designed for workshops, facilities teams and home mechanics, Zep 45 combines fast-acting penetration with a durable lubricating film. Its formula quickly seeps into threads, hinges and seized fasteners to reduce friction and help free stuck components while leaving behind a protective layer that resists moisture and corrosion. The aerosol offers a dual spray pattern—fan mist for coverage and pin-point for targeted application—so you can adapt to broad surfaces or tight spots.

How quickly does it free stuck bolts, hinges and fittings?

Zep 45 is formulated to penetrate corrosion and scale rapidly, easing movement and reducing the force needed to turn or pull fasteners. While results depend on the severity of corrosion, many users see noticeable loosening within minutes after application. It’s especially effective when allowed to soak into threads before applying torque.

• Rapid capillary action reaches into tight threads and crevices
• Works on rusted bolts, stuck hinges, seized bearings and corroded fittings
• Often reduces required torque and prevents rounding of heads

What protection does it provide against wear and moisture?

After penetrating, the product leaves a lubricating film that reduces friction between moving parts and slows wear. That film also repels water and helps prevent new rust from forming, extending component life between maintenance intervals. It’s useful for routine preservation as well as emergency releases.

• Long-lasting lubricating residue reduces metal-on-metal wear
• Water-displacing action protects valves, switches, and electrical contacts
• Helps minimize corrosion in humid or wet environments

Which applications and industries is it best suited for?

Zep 45 is versatile and appropriate for maintenance tasks across many settings, from vending machine servicing to metal fabrication shops. It’s formulated to perform without compromising penetrant action, making it a good choice for both preventive upkeep and repair work. The aerosol format and dual spray control make it convenient for confined spaces or wider surfaces.

• Ideal for repair shops, facilities maintenance, and manufacturing plants
• Commonly used on vending machines, hinges, fasteners, chains and cables
• Handy for hotels, recreation clubs, builders’ yards and fabricators

How do I apply Zep 45 safely and effectively?

Shake the can, choose the fan or pin-point spray, and apply to the affected area from a recommended distance—usually a few inches. Allow time for the formula to penetrate before attempting to move the part; for heavy corrosion, repeat applications may be needed. Use in a well-ventilated area and follow standard aerosol safety guidance on the label.

• Select fan mist for broader coverage or pin-point for precise spots
• Let the product soak several minutes for best penetration
• Reapply as needed and ventilate during use for safety

Who is this for? Zep 45 Dual Force Penetrant and Lubricant is made for technicians, maintenance staff, metalworkers and DIYers who need a dependable, fast-acting solution to free stuck parts and protect equipment. If you maintain machinery, service vending or rental equipment, or simply want a go-to aerosol for stubborn rust and routine lubrication, this 14-ounce can gives a compact, professional-grade option that balances penetration with lasting protection.
