SONAX Engine Cleaner | Powerful Engine Degreaser for Oil & Grease Removal | Safe on Metal, Plastic & Rubber | Phosphate & Solvent-Free Formula | Deep-Cleaning for Hard-to-Reach Areas | 543200 | 500 ml

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.

Worked well. I did have to use a detailing brush to scrub the thicker grease.

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

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

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