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.

Great product

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.

The nuts holding the passenger side cat of my 2017 Mustang GT were stuck on. Sprayed with Liquid Wrench and let sit over night. Came back the next day sprayed again and tapped the flange with hammer and they came loose with a breaker bar. This stuff really works but requires a little patience. Also once you get passed the smell you got it licked.

This was tested as a penetrator that far surpassed all others that cost way more… check evaluations on Performance Farm website testing..

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.

Cake damaged and bottle leaking terrible smell

Quality product! Works as advertised!

Nix besonderes bin eher enttäuscht. Der Rost der behandelten Teile wurde nicht richtig gelöst

Worked great on my bike chain, freed up the seized up chain links

This stuff works.
