Review: WD40 - Some of the best oils - WD40 Penetration oil does the job on rusted nuts and bolts, it is designed to penetrate deep into the bolt to help release and breakdown corrosion and seeps really well and works fast, it can also help with water resistance to prevent further corrosion and I've been using the WD-40 brand for years, with WD-40 you know what you're buying, you know the quality is some of the best on the market, the flexy tube and wide spray is extreamly useful in those tight situations, you might see cheaper oils on the market, but if you want quality then this is the spray that you need.
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

### ⭐⭐⭐⭐⭐ Works fast on stuck bolts – a must-have in the toolbox
*by C***A on 30 September 2025*

I recently added the WD-40 Specialist Penetrant Spray to my toolkit, and it has already proven its value. I used it on a couple of stubborn, rusted bolts in my bike and an old garden tool, and within minutes the parts loosened up with very little effort. The spray penetrates quickly and doesn’t have the messy residue that some similar products leave behind. The nozzle gives a controlled spray, so you can target tight areas without wasting product. The smell is noticeable but not overpowering, and it doesn’t linger for long. One thing to keep in mind is that this is designed mainly as a penetrant and not as a long-term lubricant, so after freeing stuck parts it’s best to apply something else if you want ongoing protection. Overall, this is an effective, reliable product that does exactly what it promises. Definitely worth keeping on hand for household repairs, bikes, cars, or any mechanical projects.
