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.

Limpiador de excelente calidad ya llevo varios años y cuando se me acave volver a comprar otro

Will do a descent job, but there are other ways and products to clean your motor that's much cheaper.

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've been upgrading my car and was getting tired of having soot and grime on my arms, hands, and under my nails for weeks every time I worked on it... but as an adult with a career and family I don't have time to give it a proper detail. I found a video praising P21S for it's ability to fully clean an engine bay with minimal effort. It truly made a night and day difference in my use case. I just placed plastic bags over the alternator and intake filter, sprayed the whole engine bay down with P21S, and then used a garden hose with a low pressure nozzle to thoroughly rinse. I could not be happier with the results!

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.

I have too many cars and motored stuff. I use a spray bottle of this cleaner mostly on my engine, I prefer it over Gunk. This size bottle really lasts and saves me over the spray bottle size, so I reuse the bottle and refill it.I definitely recommend this cleaner, and you’ll find uses for it besides what I mostly use it for! Even a general wash. Works well, smells great, and cleans quickly with easy spray wash to remove (spray until the soapy residue is gone)

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.
