BG penetrating oil 15.7 oz (PN 438) — ion-activated foaming formula for rusted parts, long-lasting lubrication

BG In-Force is an ion-activated penetrating oil that breaks free rusted parts, stops corrosion, and provides long-lasting lubrication with minimal run-off.

BG In-Force Penetrating Oil (15.7 oz, PN 438) uses an ion-activated formula and controlled foaming action to penetrate tight metal interfaces more effectively than conventional penetrating oils. It loosens seized bolts, hinges, locks, and braided cables, while leaving a corrosion-inhibiting lubricant film that helps protect surfaces during storage or assembly. Designed for heavy-duty automotive, industrial, and household use, the product reduces waste through reduced dripping and targeted foaming.

How does BG In-Force get into rusted or frozen parts?

The ion-activated chemistry helps the lubricant cling to and migrate along metal surfaces, while a gentle foam expands into seams and threads to reach corroded contact points. Light mechanical action such as tapping speeds the process, and repeat applications can be used for very stubborn fasteners.

• Ion-activated molecules for improved metal surface attraction
• Foaming delivery expands into narrow gaps and threads
• Works faster when combined with light tapping or movement

Where is this penetrating oil best applied?

BG In-Force is formulated for a wide range of metallic surfaces and assemblies: locks, door hinges, sliding mechanisms, firearms, braided cables, and seized fasteners are common examples. It also functions as a preventative lubricant during assembly to delay corrosion before it starts.

• Locks and latches — restores movement and prevents sticking
• Hinges and sliding assemblies — reduces friction and wear
• Fasteners, bolts, and cables — loosens rusted hardware and frees seized parts

How should I use BG In-Force safely and effectively?

Spray the affected area and allow a few moments for the penetrating action; tapping the part helps the formula work deeper. In difficult cases, repeat the spray-and-wait cycle. Use in a well-ventilated area, avoid open flames, and follow local disposal and safety guidance.

• Spray onto the corroded area and let the foam penetrate
• Tap or move the part to accelerate loosening
• Reapply when necessary; store upright away from heat

What protection and limitations should I know about?

BG In-Force provides a corrosion-inhibiting lubricating film but is not a permanent rust-proofing coating. It helps delay corrosion and reduce friction; for long-term protection consider dedicated corrosion inhibitors or protective coatings. Note regulatory cautions and use appropriate PPE when applying.

• Leaves a protective lubricant film but not a permanent seal
• Not a replacement for specialized long-term rustproofing systems
• Follow product safety warnings and ventilation recommendations

Who is this for: BG In-Force suits mechanics, maintenance technicians, firearm owners, marine and industrial operators, and homeowners who need a dependable penetrating oil that reaches tight metal interfaces. It's ideal for anyone who regularly deals with rusted or frozen hardware and wants a targeted foam-based formula that minimizes run-off while providing corrosion inhibition and lubrication.
