This is the best penetrating fluid I have ever used!!! Spray on the rustiest, seized up bolt, nut, screw, etc. Within 5 minutes, it gets loose. no impact, no breaker bar, just a wrench, socket, or heck even pliers. done and done! 👍👍⭐⭐⭐⭐⭐

Don't have the strong smell

I saw this spray on YouTube and had to give it a try. It did the job just as well as the other name brand but does not have the strong smell.

I have used PB Blaster for years but this knocker loose is really good. it doesn't take too long for it to soak in. and then it really helps getting any kind of rusted bolt off. for me it's a 9 out of 10
