Smack gee t'ack, alright!


Hard water

I bought this product just as a fluke because I have tried everything else on the market! The label said degreaser so I thought I'd try it on my shower. My shower is clear glass and we live where the water is so hard it barely runs! I sprayed the W-D on my shower and almost instantly I began to see clear glass! It also removed the soap and body oils from the wall! I love this product and hope that continues to sell and they DON'T change the formula!


fantastic cleaner

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.

Amazingly great and no smell like others

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

Did not do cleaning good

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!


A true degreaser!

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!


Perfect- Cleans well, water based

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.


Clean Great!

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!


disolves fresh oil!

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
