Liquid Wrench L106 Penetrating Oil, 5.5 Oz

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.

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

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.

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.

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.

Never fails to help crack loose stubborn nuts, bolts, screws, spark plugs, and helps get in to lubricate tight tolerances.

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

Ever since watching the "Project Farm" episode on YouTube a couple years ago, where he tested a bunch of the most popular penatrating oils / lubricants against eachother in a test and this 'yellow labeled' version of "liquid wrench" came out on top by a significant margin, it has been my can of choice since. Only problem is it has been hard to find in stores. Picked up this 4 pack here on Amazon for a decent price.

Cake damaged and bottle leaking terrible smell

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

This stuff works.

good price. very difficult to find other than in spray cans. should last 25 years!
