PB B’laster Penetrant
Deep-Penetrating Oil for Rusted Bolts, Seized Fasteners and Corroded Parts
PB B’laster Penetrant is a petroleum-based penetrating oil designed to work into rusted, corroded, stuck and frozen metal components. Its capillary action helps the penetrant creep into threads, seams and tight spaces where rust and corrosion can make disassembly difficult.
After penetrating the affected area, PB B’laster leaves behind a non-evaporating lubricating film that helps lubricate the component and provides additional protection against rust and corrosion.
It is commonly used for automotive repair, industrial maintenance, farm equipment, machinery and general repair work where nuts, bolts, pipe threads and other metal components have become difficult to remove.

Penetrates Rusted and Frozen Parts
Rust and corrosion can bond threaded fasteners and mating metal surfaces together, making normal disassembly difficult.
PB B’laster uses capillary action to move into narrow spaces around threads, seams and other hard-to-reach areas. Saturating the affected area allows the penetrant to work between corroded surfaces and help loosen the bond created by rust.
Common uses include:
- Rusted nuts and bolts
- Seized fasteners
- Corroded pipe threads
- Brake hardware
- Exhaust components
- Suspension components
- Machinery
- Agricultural equipment
- Automotive repair
- Industrial maintenance
- General mechanical repair
How to Use PB B’laster
- Shake the aerosol can thoroughly before use.
- Saturate the rusted or seized area with PB B’laster.
- Allow the penetrant several minutes to work into the affected area.
- Lightly tapping the component can help the penetrant move into corroded interfaces.
- Reapply when dealing with severe rust or corrosion.
- Allow additional penetration time when necessary before attempting removal.
There is no universal dwell time. Heavily corroded components can benefit from additional time and repeated applications.
Lubrication and Rust Protection
PB B’laster does more than penetrate corrosion. After application, a non-evaporating lubricating film remains on the treated component.
This residual film helps provide lubrication during disassembly and can help protect the treated surface against additional rust and corrosion.
PB B’laster is best considered a penetrating lubricant and rust penetrant. For applications requiring dedicated long-term corrosion protection, use a product specifically designed for extended rust prevention.
Metal, Paint, Rubber and Plastic Compatibility
PB B’laster is suitable for use on metals including:
- Steel
- Aluminum
- Brass
- Copper
- Iron and other common metals
B’laster states that PB B’laster will not affect a factory-quality automotive finish. Lower-quality or refinished paint may react differently, so test an inconspicuous area first.
Use more caution around rubber and plastic. Long-term exposure can affect lower-density rubber and plastic materials, while higher-density materials may experience surface softening.
Silicone-Free and Body-Shop Safe
PB B’laster does not contain silicone and is identified as body-shop safe.
Before painting a treated metal surface, remove PB B’laster completely with an appropriate surface-preparation solvent. Residual penetrating oil should not be left on a surface that will be painted.
Flammability and Hot-Surface Use
PB B’laster aerosol is classified as flammable.
The current technical data sheet lists a typical liquid flash point of 150°F (66°C). Keep the product away from flames, sparks and other ignition sources, and use caution around hot surfaces.
Do not spray PB B’laster onto an open flame or ignition source.

Frequently Asked Questions
What is PB B’laster used for?
PB B’laster is a penetrating oil used to help loosen rusted, corroded, seized and frozen metal components such as nuts, bolts, pipe threads, brake hardware, exhaust fasteners and suspension components.
Is PB Blaster a penetrating oil?
Yes. PB B’laster is a petroleum-based penetrating lubricant specifically designed to work into rusted and corroded components.
Does PB Blaster remove rust?
PB B’laster helps penetrate rust and break loose components that have become seized by corrosion, but it is not a chemical rust remover intended to dissolve and remove all rust from a surface.
How long should PB Blaster sit before removing a rusted bolt?
There is no fixed dwell time because the amount of corrosion varies. Allow at least several minutes for penetration. Heavily rusted fasteners may benefit from repeated applications and additional penetration time.
Can PB Blaster be left overnight?
Longer penetration time can help on heavily corroded components. Repeated application over a longer period may improve penetration when a fastener is severely seized.
Does PB Blaster leave lubrication behind?
Yes. PB B’laster leaves a non-evaporating lubricating film behind after penetrating the affected component.
Does PB Blaster prevent rust?
The residual lubricating film helps provide protection against further rust and corrosion. PB B’laster is primarily a penetrating lubricant rather than a dedicated long-term corrosion coating.
Is PB Blaster safe on metal?
Yes. B’laster identifies PB B’laster as safe for metals including steel, brass, copper and aluminum.
Is PB Blaster safe on car paint?
B’laster states that it will not affect a factory-quality automotive finish. Lower-quality repaint work may be affected, so test an inconspicuous area first.
Is PB Blaster safe on rubber and plastic?
Compatibility varies. Lower-density rubber and plastic can deteriorate with prolonged exposure, while higher-density materials may experience some surface softening. Avoid unnecessary prolonged exposure and test questionable materials first.
Does PB Blaster contain silicone?
No. PB B’laster does not contain silicone and is identified as safe for use in body and paint shop environments.
Is PB Blaster flammable?
Yes. The aerosol is classified as flammable. The current technical data sheet lists a typical liquid flash point of 150°F (66°C). Keep it away from sparks, flames and ignition sources.
Can PB Blaster be used on hot parts?
Use caution. B’laster recommends caution around hot surfaces, especially when an ignition source is present. Do not spray the aerosol onto flames or other ignition sources.
Can PB Blaster be used on brake and exhaust components?
Yes. Brake, exhaust and suspension repairs are specifically identified as common PB B’laster applications. Avoid contaminating brake friction surfaces such as pads, shoes and rotors.
How do I remove PB Blaster before painting?
B’laster recommends removing the product before painting. Soap and hot water can be used for general cleanup, while a suitable prep solvent should be used to prepare a surface before paint.
