Blaster PB Blaster Penetrating Oil 18 oz Big Shot (6-Pack) — Rust Remover, 360° Valve & Easy-Press Spray

If you work on cars, motorcycles, farm equipment or mechanical assemblies, stuck fasteners and rusted components are a frequent, time-consuming problem. PB Blaster Big Shot delivers a low-surface-tension penetrating catalyst in an 18 oz aerosol can so the formula flows deep into threads and tight crevices to break corrosion bonds. This six-pack offers extra capacity for long jobs or an organized workshop supply, and the 360-degree valve plus easy-press actuator make awkward angles and upside-down access practical on the job.

How does PB Blaster loosen rusted bolts and seized parts?

Its fast-penetrating formula works by reducing surface tension and creeping into microscopic gaps between corroded metal surfaces. Once inside the threads, it helps dissolve and displace rust, allowing the parts to move with less force and reducing the need for destructive extraction methods.

• Low surface tension to reach tight threads and crevices
• Penetrating catalyst designed to break rust bonds
• Leaves lubricant film to assist turning and removal

Can I use this on vehicles and mechanical equipment safely?

PB Blaster is engineered for automotive and general mechanical use — it’s suitable for nuts, bolts, chains, hinges, and other rusted metal parts. Follow standard safety and compatibility checks: avoid painted surfaces if prolonged contact is expected, and test on a small area if unsure about specific materials.

• Recommended for bolts, fasteners, hinges, and stuck hardware
• Works on automotive, agricultural and workshop equipment
• 50-state VOC compliant for broad regulatory compatibility

What makes the Big Shot aerosol convenient for frequent use?

The 18 oz Big Shot can gives more product per can for extended tasks and regular shop use, reducing the need to switch cans mid-project. The specially engineered actuator and 360-degree valve let you spray from any angle — including upside down — so you can access awkward spots without repositioning the assembly.

• Large 18 oz capacity for longer jobs and professional use
• 360-degree valve for spraying at any orientation, even upside down
• Easy-press actuator speeds repeated applications and reduces finger fatigue

How should I apply PB Blaster for the best results?

Apply a liberal coat to the stuck area, allow time for the formula to penetrate — often several minutes to hours depending on severity — and then work the fastener back and forth. For stubborn cases, reapply and use light impact or heat (where safe) to help break the bond; always follow safety guidance for heating and flammable materials.

• Spray directly on the corroded thread or joint and let it soak
• Work the fastener periodically to help the formula migrate deeper
• Reapply as needed; pair with heat only when safe and appropriate
