Review: Effective and Affordable - 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.
Review: Rusty Bolt Removal - 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 desertcart 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.

## Questions & Answers

**Q: Can i use liquid wrench penetrating oil on a large pvc water shut off valve? it runs to a waterfall. it has been buried for years and won't budge.**
A: It should not hurt the pvc. If valve has been buried, I would first clear around it then clean it as best as possible. Take a hair dryer or heat gun(be very careful with heat gun) and warm, just warm valve, let cool and warm again. Apply liquid wrench let sit 10-20 mins. Use valve wrench to try and open valve, repeat id necessary. Heat done right(low) ought not cause any problems with liquid wrench which is a flammable.

**Q: After it dries, does anyone knows if it will prevent rust?**
A: It does prevent rust. Been using liquid wrench for 40 years to prevent rust on my tools stored in my garage. After iI use a metal tool I spray it with Liquid Wrench. Never lost a tool due to rust.

**Q: Is it safe to use for breaking loose rusted stuck exhaust bolts? i know it is flammable but i figure i could clean it off after i get the bolts out.**
A: It won a comparison between 5 other well known rust penetrators by a well know product evaluator on YouTube. But the ultimate exhaust bolt fix is heat if all else fails.

**Q: Does this form a foam when sprayed on ??? J. Payne**
A: No, it is more like the consistency of WD-40. It bubble a little when you first spray it (probably from the propellant) but it leaves more of a thin (penetrating) oil residue.

### ⭐⭐⭐⭐⭐ This stuff is magic
*by C***N on June 11, 2025*

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.
