Cleaner Degreaser Gallon

The Cleaner Degreaser Gallon from POR-15 is a heavy-duty solvent engineered for mechanics and automotive enthusiasts who demand professional-grade cleaning power. Whether you're prepping an engine bay for restoration, removing decades of accumulated grime before welding, or degreasing suspension components, this gallon-sized formulation delivers the industrial-strength cleaning that serious vehicle work requires. From engine blocks and transmission housings to undercarriage parts and drivetrain components, POR-15's cleaner degreaser cuts through stubborn buildup without compromising your project timeline.

This formulation works by breaking down molecular bonds in grease, oil, tar, and oxidized deposits, allowing them to emulsify and rinse away cleanly without leaving residue behind. The solvent-based chemistry is potent enough to handle carbon accumulation and baked-on oils typical of high-mileage or long-stored vehicles, yet it's designed to evaporate quickly and completely—critical when you need a dry surface for primer application, welding, or coating work. The gallon size (8.63 lbs) provides substantial coverage for full-scale restoration projects or multiple repair cycles, making it economical for both professional shops and dedicated home builders tackling frame-off restorations or engine rebuilds.

POR-15's Cleaner Degreaser is ideal for anyone preparing surfaces before applying POR-15 rust preventative coatings, ceramic engine enamel, or epoxy primers—a critical step that determines coating adhesion and longevity. Mechanics working on restoration projects, vintage car enthusiasts, and fabricators performing welding or metal work will appreciate the clean, dry finish this product leaves behind. Use it on bare metal, cast iron, aluminum, and steel components; always follow local environmental guidelines for disposal and ensure adequate ventilation when working with solvent-based products in enclosed spaces.
