selsil Professional Engine Cleaner and Degreaser Spray, 16.90 fl oz, Non-foaming Engine Cleaner Spray, Removes Oil & Grease, For All Types of Engines Automotive, Industrial & More, 1 Pack

It worked great for the inside of my car! I put a bunch of rags all over the stuff I didn’t want affected and it came off with one wipe. What was cool though was that this works on the driveway too. I lazily sprayed it on before pressure washing out of curiosity and it came off instantly!

excelente producto. Muy buen producto para la limpieza de motor

I used it on a cold engine, with a piece of paper towel not even a rag. The parts I did came out really nice. I can imagine what it would look like if I did it the right way. Great product. Glad I got it.

This stuff worked great what else can I say.

I used this to do some cleaning on my boat motor. The motor was fairly clean, just some light grime and residue. It did a great job with this. It left the surfaces clean and looking new. In the areas where I had belt filings from the serpentine belt it didn’t works so well. It did loosen up some of the rubber “dust” but this isn’t a real grease mess so I expected limited results with this. More stubborn greasy parts may require some agitation with a brush to fully remove. It did work and live up to my expectations. I haven’t tried it on a real dirty engine like my diesel equipment and can’t speak how it will do with that. I have some left and will give it a try when it gets a little warmer.

Works very well

Does a great job

Yeah, it kind of works but it is not the be all end all solution I feel it claims to be. Added a before and after of my little VW engine that I tried this product on. You can see that engine compartment cleanliness is not one of my priorities. I live in the high desert and am on gravel/dirt roads quite often so this little clean-up won't last long at all. If you look closely at some of the nooks and crannies you'll see that a lot more scrubbing is required than implied. Used the better part of a whole can to do this little job so it seems to me cost to value ratio is not the greatest. No offensive or strong chemical smell which is good. No specific statement on can as to removal from surface product is used upon. Do I rinse or wipe? I went with rinsing and was kind of surprised at how water beaded up on all surfaces after rinsing... makes me wonder what residue is left and will it actually attract dirt and dust? Bottom line, product kind of lived up to it's marketing but not completely in my opinion. I see other reviewers are quite happy with this for non engine compartment applications so that type of use may be where this product shines. YMMV to be sure.
