Works fast. Watch a YouTube video on how to use to be safe.

I've used this for years. From keeping the engine compartment of my car looking showroom clean to my home a/c condenser super clean. Dilute to the type of use. Rinses clean. So works great, easy to use and excellent quality and value.

I have to admit I bought this for a much dirtier job than regular engine cleaning, so my review is based on HEAVY grime. My new-to-me truck has an undercarriage with lots of grime and some surface rust on critical frame and suspension components, so I bought this to try it out and see how well it cleans off the grime layer so I can see exactly how bad the rust is. And I have to agree it works very well in getting layers of regular grime and dried grease off. It didn't clean everything spectacularly well, and it left some brake dust on the inside of the wheels despite a second application, but for the most part it did a good job and I'm pleased. I'll do additional applications underneath and see if it helps get more off. Eventually I'll need to de-rust and then undercoat the frame which will be a big job, but the first part is getting the underside clean and the P21S did a good job for that.

I'm amazed at how well this works to clean up the engine bay! Sprayed it on, waited, then hosed it off. Zero scrubbing. And everything comes out clean! Love this.

P21S make best cleaner for fire truck, cleans diesel soot and brake dust. Loving wife say I should use it in shower. 10/10 would buy again.

I got this to clean out my engine bay after a "genius" at a local automotive shop with "the golden touch" forgot to put the dipstick feed tube back on the engine after replacing my catalytic converter. Needless to say, the oil spray all over the engine and bay area was rather prolific by the time I got home. Not only did the P21S eat through all of the fresh oil from this little faux pas, it also made light work of the built-up oil and residue from the last 18 years of normal, daily driving. In fact, I had to do very little scrubbing. Simply applying the P21S via a garden sprayer (pressurized by a hand pump), waiting 10 minutes, then following up with rinsing very well using hot water via a second sprayer was all I needed. I would highly recommend this to anyone wanting to effortlessly clean their engine and engine bay without spending an entire afternoon performing back-breaking scrubbing and cleaning.
