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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Loosens rusty bolts well *by on Reviewed in the United States 8 August 2026* This is a very low-priced penetrating oil, but seems to work as well as the more expensive kinds, such as PB Blaster. I use it almost every day. ### ⭐⭐⭐⭐⭐ Best penetrating oil in the market *by on Reviewed in the United States 18 May 2026* Best penetrating oil there is. Spray it on tap the bolt a little bit. Give it a few minutes to work and will come right out. My neighbor is trying to change the oxygen sensor on his car and turn it no matter how hard he tried. I loaned him a can of this stuff. He sprayed it on tapped it a couple of minutes and five minutes later he had it off no problems. ### ⭐⭐⭐⭐⭐ Effective and Affordable *by on Reviewed in the United States 17 January 2026* 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. ## Frequently Bought Together - Liquid Wrench L112/4-4PKLIQUID Wrench L112-4PK Penetrating Oil Spray - 11 oz., (Case of 4) - WD-40 Original Formula, Multi-Use Product with Smart Straw Sprays 2 Ways,12 OZs, 3-Pack, 12 OZ - Non-Chlorinated Brake Parts Cleaner, 14-oz., Pack of 4 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/637607793-liquid-wrench-l112-4-4pk-penetrating-oil-with-cerflon-11](https://www.desertcart.sn/products/637607793-liquid-wrench-l112-4-4pk-penetrating-oil-with-cerflon-11) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-29*
