Liquid Wrench L106 Penetrating Oil, 5.5 Oz

Effective and affordable. Liquid Wrench is an honest-to-goodness product that does what it should without pretending to do more than it can. Too many other brands try to justify a higher price by claiming to be "professional" or "industrial" grade. As a penetrating oil, its proven to work better than Kroil and WD-40; which I was partial to for many years. The quantity/ price-per-ounce is also good value. Good viscosity, low-odor and works well to prevent flash rusting. Each bottle includes a straw for more direct application. Just for fun, I also like that the cap is shaped like a nut.

Works well. I used this on a rusted bolt that was impossible to remove it just wouldn't budge. I tried all products. I found this on Amazon and low and behold it works and really well. I sprayed it on the bolt and let it sit for a while and just like that I finally removed the bolt that has been pestering me for some time. Good value. Use in a well ventilated area. Easy to use just point & spray.

Im never the type of leave reviews but this stuff is amazing. I had a seized spark plug so i sprayed this and let it sit for a few hours and it broke it free. It should be called liquid gold.

works good for everything / but it dose have a chemical smell to it

This stuff works. I have a 2000 Jeep Grand Cherokee that I just bought recently. For most of its life, the Jeep lived in the cold, windy climate of Cleveland, Ohio, where lake-effect snows can wreak havoc on the metal components of any vehicle - especially after 13 years. Many of the engine's bolts are rusted and impossible to get loose. A generous lathering of this stuff does the trick on most pesky bolts. You have to use quite a bit of it and make sure it works its way into the nut. It's low viscosity allows it to penetrate into very tight-fitting areas. Depending on how bad the bolt is, let the liquid sit for a while - anywhere from a few minutes to a few hours. Then, have at it. It was able to loosen up every troubled bolt I had on my Jeep. My only complaint is that the red wand would not fit into the nozzle. I tried everything I could to get it to fit. I even grabbed another wand off another bottle, but COULD NOT get the wand in the nozzle. Not sure if I had a bad nozzle or if they're all like that, but it's pretty annoying. Other than that, this is a great buy and good to have around the garage.

This is THE BEST penetrating oil on the market today in my opinion!

I use these on my locks and other items they were fine

This brand is my preference
