FR-90 is an advanced penetrating oil that shocks rust down to -40.deg C, creating micro-cracks, allowing the lubricants to penetrate faster for rapid fastener removal. The silicone free formula is safe for use on all metals surfaces and most plastic, paint and rubber coatings. FR-90 can be used to release seized/rusted nuts and bolts, valves, heating pumps, immersion heater and fused parts.
