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.


Easy cleaning

I've used this on a few things from simple craft machines to the engine on my old car. Just simply spray on build up. Let the product sit for a few minutes, then easily wipe away grime with ease. No mess and limited clean up. Great for so many things.


Wow just wow!

This engine degreaser is a life saver for my 2012 model. Looks like engine was never cleaned and I used this to try without having much expectations. But I was so pleasantly surprised. it did the job well with not much effort except some stubborn grease that came off with a scrubber. Highly recommend!



Really surprised how great WD-40 the foaming spray worked to removd grease and dirt on my machine equipment. I have not cleaned some equipment in forever and this degreaser did the job to make them look good again. It doesn't take much and thats what I really liked. It removed oil on some tools as well, I am really happy and recommend to everyone.
