PB Blaster Penetrating Oil Spray, 11 oz Aerosol Cans (12-Pack) – Rust Remover & Bolt Loosener for Stuck Nuts, Bolts & Rusted Parts – Penetrating Catalyst for Automotive & Mechanical Use

PB Blaster Penetrating Oil Spray is a high-performance penetrant designed to tackle rusted and frozen fasteners. Powered by a proven penetrating catalyst, this penetrating oil spray works into rust and corrosion to help free stuck nuts, bolts, and mechanical parts with less effort. The low surface tension formula allows the oil to creep deep into threads, seams, and tight spaces, attacking corrosion from the inside out. By loosening seized hardware more effectively, PB Blaster helps reduce the force required during disassembly and lowers the risk of snapped bolts or damaged fasteners during repair and maintenance work. Beyond freeing stuck parts, PB Blaster also leaves behind a protective film that helps block moisture and slow future corrosion on metal surfaces. After freeing seized components, a dedicated spray lubricant can be applied to support long-term operation once parts are moving freely. Designed for precision and control, the ProStraw with Control Flow Technology lets you adjust spray volume and switch between pinpoint and wider coverage without changing straws, helping apply product exactly where it’s needed with less mess. Trusted by professionals and DIYers alike, PB Blaster delivers reliable penetrating oil performance for automotive, garage, and home projects.
