## Description

From the manufacturer

Review: Does what it says on the tin - Worked well on seized bolts and rusty hinges. The Smart Straw makes it easy to apply accurately without wasting product. A useful addition to any toolbox.
Review: Brilliant stuff; spray, leave it for 10-15mins, come back and undo what couldn't be undone! - Absolutely superb stuff this; never used it before today and it worked a treat. My usual go-to is standard WD40 then Wurth Rost Off Ice - but ran out of that and the prices have gone silly. Thought I'd try something different and glad I did... Needed to change all the front suspension arms and track rod ends on my 2002 BMW 540i this morning whilst I was able to use my pals ramps; got the car up, wheels off, soaked all the ball joints, nuts and large bushes, nuts & bolts and left them to soak whilst I made a brew etc... Came back; all bolts undid and nuts; the ball joints were easy enough to pop out without having to resort to violence, ball joint splitters/forks or heat etc - yes they took a few whacks with a peacemaker; but they came out without any issues Very impressed and would highly recommend
