I am restoring my Honda pilot fl400r after it was sitting in storage for 17 years and had accumulated a nasty layer of grime and dried in oil. sprayed the engine with this and I only had to use a toothbrush for a few nooks and crannies to make it like new. the engine has come up like it was only stored yesterday.

I recently bought an older car and it had years of oil spills, dirt and grime. I looked on line and found a few products that are petroleum based, smells bad and damages hoses. I trust WD-40 lubricant so I thought I would try the Engine Degreaser. AMAZING results in 5minutes!! You could eat off this engine now! If you wish. Thanks WD-40

I sprayed this foam to clean the oil pan on my car because pan was leaking oil for sometime. It did the same thing as if I sprayed water, so no cleaning at all!

This stuff cuts through anything. I have used this on a 20 year old white engine bay. Just spray it on and wipe it off with a rag. Looking a the photo you can see where I worked on the driver side. Spray and wipe. It works great on stain gutters too!

Used to clean aftermath of a small engine oil leak on a Cosworth engine and Hewland FTR sequential gearbox in a Fromula 3 car. Spraying on a harsh cleaner then hitting it with the garden hose wasn't an option. What I liked about the WD-40 Engine Degreaser was: 1. Water based, I could spray, allow to work for a few minutes and use the ShopVac to remove liquid residue. 2. Spray stream to point and shoot at hard to reach nooks and crannies. 3. A light, non-objectionable smell. No strong smell like some engine cleaners. 4. No residue. 5. Easy to wipe away what I didn't vacuum up. 6. Cleaned well. 7. Doesn't damage aluminum or carbon fiber. Met my needs perfectly, thank you WD-40 for a well-engineered product.

I purchased this today and thought it would be great to clean my AR15 with it, bad idea. It is not strong enough to take of grimy black carbon build up.

I was rebuilding a Honda ATV engine and want to clean the mud stained crank case before I reassembled it. The product sprays on easy and holds to the metal until you remove it. I let it soak and used a stainless wire brush on the alumnium case and it make it look brand new!

I spilled 2 stroke oil on my boat fuel tank, and the engine was very grimy for years. Today I was in Sams and bought a 2 pack of the WD40m foamy degreaseer for less than 5$, this is a dollar and a half cheaper than the competitive can of degreaser, so the price was great. I used the spray dergeaser, and it completely removed the oil and privious grime after a couple sprays. The foam keeps expanding and works longer than anything I have ever saw before. The dirt sort of strayed, but this easily washed off with soapy water. I will be going back tomorow and plan on buying a few cases of this product, it is way better than foamy degreasere, or any product I have used yet in a can. I does have an amonia smell to it, so this may be the secret. Jay in Alaska
