I ended up googling a video of someone using this product because I just was t quite sure how safe it was and where/how to use. It is simple enough, just spray and let sit. It did a good job, but definitely requires more than one application and some time.

Thank you for sharing your thoughts and experiences with this product. We appreciate your feedback and hope WD-40® Brand Products continue to serve you well in the future.

Easy and works as desrcibed

I used this to clean a couple of small engines. First on my snowblower and then on my lawnmower. The product was easy to use and foamed right up and the dirt and grime rinsed away. Very easy to use!


WD40 always delivers

I chipped the engine case on a dirt bike from a snapped chain which left a small crack on the side. This degreaser made it simple to clean the engine side cover of leaked oil. I was able to clean it, sand and apply a cold weld to the bike and now it runs like new!


Great product

Makes easy work out of messy (greasy) situations. When you spray on the product if foams up and the grease melts away. Wait a few minutes and then rinse the foam off. No need to wipe with down and your tools come out super clean.


Works great!

The WD-40 Specialist Machine & Engine Degreaser is definitely worth the money. It works better than just regular WD-40. I was very impressed how it foamed you and you could rinse off the grease so well. I was rebuilding a 6.0 diesel motor and it was extremely dirty. I sprayed the motor down. It cleaned it up nicely allowing me to work on it and leave it looking better than it was before.  I also wiped it off in some areas. It worked very efficiently and was easy to clean it up. I highly recommend everyone have some WD-40 Specialist Machine & Engine Degreaser when working on vehicles or other motors.


Excellent DeGreaser - Works Great!!

Used the WD-40 Specialist Degreaser to remove some excess oil around the engine and it did the job. Easy to use and foam spray came out smoothly. I also used it to clean my wheels to remove dirt, oil and grime - no problemo. Highly recommend this product.


Works as advertised

Works pretty good. It foams up just like every other degreaser except this is from a brand most people trust and have trusted for generations. Cleans most grease and grime off with a single application. Definitely a product I would recommend.


Works great on caked on oil and dirt!

Had oil and dirt all over my 88 fiero engine block and I let this sit on it for about 30 mins and just about everything came off with a basic rag. Would definitely recommend using this to clean an engine with.


WD 40 Specialist Machine & Engine Degreaser

This is a good cleaner for removing grease, oil, dirt and grime. This product works very good because it is a deep penetrating foam action and leaves a low residue. It is a good product for cleaning any kind of greasy or dirty parts or machinery. You just spray it on, let it sit for a while, wipe it or hose it off.


Perfect for my boat

This is a great degreaser perfect for keeping my boat in tip top shape. I use it to help winterize in the fall and make sure it's ready to go in the water come spring time. I love how easy it is to dispense and the foaming action does a thorough job of removing all the grime of a hard seasons work on the lake.
