L112/4-4PKLIQUID Wrench L112-4PK Penetrating Oil Spray - 11 oz., (Case of 4)

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.

I saw Project Farm's penetrating oil comparison, figured I'd try Liquid Wrench despite having poor experiences with penetrating oil in the past, and wow this stuff is magic. I drive a 30 year old Jeep. It is very very rusty. I recently undertook a major suspension overhaul. Every single one of the 31 bolts I had to remove was a rusty mess, and I expected to break at least one. I applied Liquid Wrench 7 days in advance, 4 days in advance, and the day of the project. Every single one of the bolts came out easily and none of them broke. I've never had such a painless experience working on any car - like seriously, those horrendously rusted bolts were easier to remove than some rust-free bolts I've encountered on much newer cars. Liquid Wrench is going to be the first step any time I'm working on my car going forward.

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.

Why did you pick this product vs others?: For years I overlooked this in favour of WD-40. Idk, this is very good quality rust remover. I have some old project trucks I work on an this with some butane heat will free up most bolts. Now I recommend you spray, heat an spray then let it set an come back after a day or some hours. DONT Snap a bolt rinse an repeat! Photo is Shackles being replaced on my 4x4 F150. The old bolts were seized. Also, Apparently no one has this anymore in stock. I seen it only at one Truck Stop, but none of the Big Box Stores or Hardware Stores, BECAUSE I looked after watching the comparison test from Project Farm.

Always does the job use quite a bit and give it some time.
