Review on 💪 Powerful Liquid Wrench L116 Penetrating Oil - 16 oz.: Superior lubricant for efficient maintenance and repairs by Sean Garrison

I've been trying to remove the old oxygen sensor from my 2004 Toyota Corolla for about a couple of weeks. My wife kept telling me to just take the car to a mechanic. I refused to pay $200 for such a simple repair. I bought a special tool to remove the oxygen sensor and still no bones. Despite my best efforts, that stupid oxygen sensor hasn't come off! I had some WD-40 all over the house which did almost nothing. I bought a Revain Liquid Key. I sprayed it in there and after 10 minutes I tried again and bam it came off. I don't know what that thing is, but it saved me $200 from not getting caught by the local mechanics. Thanks very much!
