Worked great and as advertised. No issues after cleaning.

This product really works; it removes the dust and the solid dirt that builds around the engine cover. Cover the wires and spray every plastic parts; leave product sit over parts for about 5 minutes then wipe with cloth. Your engine will look like new.

Pleasantly surprised! Super easy to use. Spray on, scrub a little, rinse and engine bay now super clean!

So this little guy does work wonders on my 2015 mazda 3 leaving my engine looking like new. But not that great cutting threw the deep, thick slug on a 1988 truck my husband just got. His truck is so dirty from the previous owner lack of car. But what I was able to do it cleaned the thin layers of dirt and slug. Down side I need a bigger bottle to deal with bigger jobs. Plus side is no bad smell to the spray.

Spray it on wait 3-5 minutes and hose off. Engine looks like new. Note I cover the alternator with a plastic bag just to be safe

Its ok, but not better than anything else out there. 3 stars only because of price.

Trust me, anything this company makes works.. you can buy anything from this company and know it works.

Used the product on the engine of my 1986 Mercedes 420 SEL…use it with a good bristle brush and it transforms your engine bay. Could not be happier.
