Liquid Wrench Gunk L112/6 Super Penetrant Spray - 11 oz, Gray

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.

This is my favorite product to use on old typewriters. It makes them type more smoothly without attracting dust or turning gummy with age. I typically leave it in overnight to let it sink in and free everything up. It works better than anything else on the market, I’ve tried them all.

Works like magic. Used to get an old anode rod out!

Liquid wrench is a good alternative to WD40. and tends to be less expensive.

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.

Have been working on a fused bolt for 3 months, - trying other products- the Blaster created a toxic airsituation which made it unsuitable for inside household applications and made such a mess. WD 40 did not move it, neither did “ Free All - But one good straw spray of Liquid Wrench freed it overnight! Viewed comparison video on U tube.

QUALITY...ALL THE WAY
