WD-40 Specialist Machine & Engine Degreaser Foaming Spray, 18 OZ [4-Pack]

Works very well, used it on lawn tractor engine and compartment and cleaned all the dirt and grime off. Just sprayed, let foam up, sit and hosed off. Very convenient.

Works great

Needed this for sliding glass door rollers. Sprayed into the upper part of the roller assembly amply, grease, dirt melted away. Sprayed until clear liquid, did both sets, relubed with dry lube and rollers worked like new. Door weighs over 300 lbs, didn't want to take it off the rails, this was the best idea that worked.

Works. Empties fast. Little pricey

I didn’t want to take the risk of water or steam. I use this alone to do a gentle cleanup before selling a car. It worked.

Another quality product from WD-40.

I had a fairly bad valve cover leak on my car and after I fixed it I needed something to remove the 2+ years worth of oil that leaked onto my undercarriage parts. While working on my struts I decided to give the oil caked areas some treatment with this stuff. All I can say is wow, the way it foamed, turned brown and basically melted the oil and grime off was stunning. You don't have to worry about getting close, this can sprays quite far to reach places you'd need a straw nozzle for. So use was easy. And one thing that kinda caught me off guard was the smell. This stuff smells good. I don't know how to describe it but it's pleasant. It works so well that I didn't even need a brush to agitate it. It legitimately dripped off like melted butter. I might go back in again and hit it with some more but so far I'm very pleased. You'll be surprised by the way this stuff works when you use it. This I'm ordering again.

Works good
