Works Fantastic

I used this degreaser, for the first time in my KTM 450 dirt bike. Works great! Spray on, let it eat for 2 min, then wash off...scrubbed some small tought to reach corners and VOILA! Clean as a whistle! No more grime and looks as new:)

not effective at all

I used it to clean my bike chain and it did worse than my $2.5 degreaser. leaving a black outer and oily feel.

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.
