Description
FR-90 is a penetrating oil built for freeing seized and rusted fasteners. It shocks rust down to -40°C, cracking the surface layer and creating micro-fissures. Those tiny cracks let the lubricant work its way in faster, so you can get bolts, nuts and other stuck parts moving with less effort. The exact freezing effect depends on the starting ambient temperature, but the principle stays the same across the range of jobs you might tackle.
The formula is silicone free, which means it is safe to use on all metal surfaces without staining. It also works on most plastics, painted surfaces and rubber coatings, so you can reach for it around the workshop, garage or on machinery without worrying too much about what sits nearby. The 500ml aerosol comes fitted with a 360° valve, letting you spray from any angle, including upside down, which helps when you are working under vehicles or into awkward gaps.
We find FR-90 useful wherever corrosion has taken hold, from automotive repairs to general maintenance and outdoor equipment. The combination of freeze action and penetrating lubricant gives you a practical way to shift fasteners that have been left exposed to the weather. Each can measures 65x65x240mm and weighs 500g, making it easy to keep to hand on the bench or in a toolbox. Keep it stored away from heat sources and always follow the safety guidance printed on the can before use.

Frequently Asked
How cold does FR-90 get?
It shocks rust down to -40°C, though the actual result depends on the starting ambient temperature. The rapid cooling cracks surface rust and creates micro-fissures for the oil to penetrate.
Does FR-90 contain silicone?
No. The formula is silicone free, which is why it is safe for use on metal surfaces without staining and on most plastic, paint and rubber coatings.
Can I spray it at any angle?
Yes. The can is fitted with a 360° valve, so you can spray from all angles, including inverted, which helps when reaching into awkward spots.
What surfaces can I use it on?
It suits all metal components and works on most plastics, painted surfaces and rubber coatings. As always, test on a small area first if you are unsure.
What size is the can?
It is a 500ml aerosol measuring 65x65x240mm and weighing 500g.
