Description
Free stuck bolts fast—with extra lubrication built in.
Wurth Rost Off Extra is a professional-grade rust-penetrating oil enhanced with PTFE (polytetrafluoroethylene, commonly known by the brand name Teflon®). This advanced formula doesn’t just break through corrosion—it leaves behind a long-lasting lubricating layer that reduces future friction and wear.
Unlike standard penetrating oils, Rost Off Extra doubles as a light-duty lubricant, making it ideal for use on:
-
Rusted bolts and fasteners
-
Chains, joints, and hinges
-
Mechanical assemblies
-
Lock tumblers prone to freezing
With a larger 19oz can—nearly double the size of standard Rost Off products—you’ll have plenty on hand for your toughest jobs. The formula contains no ozone-depleting chemicals, making it a smart choice for environmentally conscious users.
Trusted by professional shops and serious DIYers alike, Wurth is a Swiss brand known worldwide for premium automotive and industrial products. Rost Off Extra is not available in retail stores and not legal for sale in California.
