McKee's 37 Engine Degreaser

Get the engine so clean, you’ll want to show it off!

McKee's 37 Engine Degreaser is the ultimate surface safe engine cleaner. It’s a blend of surfactants, sequestering agents, and emollients that immediately loosen and lift greasy buildup from engine surfaces.

McKee's 37 Engine Degreaser is based on remarkable cleaning technology that’s used to clean up oil spills in the ocean because of its ability to break up oil and encapsulate it. This same technology powers through layers of grime on engine components to uncover a factory-new looking engine.

The engine compartment is the last place many drivers clean, but it is important to the beauty and performance of a vehicle. For example, think of how difficult it is to find an oil leak if the entire engine compartment is covered in grease. Many engine problems are just easier to diagnose and repair when the mechanic can locate the problem on a clean engine.And regular cleaning will make regular, do-it-yourself maintenance much less messy.

McKee's 37 Engine Degreaser is not what you’d expect from an engine degreaser. It has no harsh fumes and it is nontoxic, VOC-free, biodegradable, and safe on any hard, non-textile surface.We’ve replaced the butyl, butyl ethers, and acid with safe, nonirritating cleaners. McKee's 37 Engine Degreaser is VOC compliant in all 50 states.

Engine Degreaser removes built up greaes and grime

But you do not have to work harder to compensate for a safer product. McKee's 37 Engine Degreaser works better than conventional degreasers. It quickly cuts through grease and allows you rinse it away with minimal agitation.

Use McKee's 37 Engine Degreaser on rubber, plastic, clear coated and painted surfaces. The surface-safe surfactants will safely clean any surface under the hood provided that it is safe to get wet.

Note: If you have bright polished aluminum under the hood, take care not to leave McKee's 37 Engine Degreaser on the aluminum for more than a few seconds as it may spot. It is best to remove these before you clean the rest of the engine. Before cleaning your engine, always cover areas that should not get wet.

After using McKee's 37 Engine Degreaser, your engine bay should be as clean as when you first drove it off the car lot: sparkling metal, clean, black hoses, and wiring connections you can actually see! In this engine, detecting a problem is easier and maintenance is much neater.

This really works! My truck engine bay wasn't dirty enough, but my sister's was a perfect test dummy. I sprayed the product all over the engine bay. I waited a couple minutes, then a lite scrubbing, followed by a rinse and wow.
Prosbiodegradeable , little effort scrubbing, show quality results

best degreaser on the market
Recently cleaned under the hood of my 70 442 W-30 , which I dont think had been properly cleaned since restoration in 1999. I have degreased several times since my ownership in the last 10 years, but never as thoroughly as it was with McKee's 37 . The results were amazing, lifted dirt and grease from raw aluminum intake manifold, as well as firewall, fenderwells and engine. As recommended a bristle brush, clean rags and a little elbow grease help as stated amazingly. On with the detailing !

Easy to use
I was always afraid to clean my BMW engine for fear that I would damage the electronics. However I hated the idea that my car was 'like new' on both the interior and exterior yet my engine bay looked horrible. I purchased the Detailer's Engine Degreaser and was so pleased with the results that I did my wife's car's engine bay, my son's Jeep engine bay, and even did my neighbor's Mercedes! I am thrilled with the results and now that nine year's of dirt has been eradicated I pledge to never have a dirty engine bay again.
ProsSimple to use and very effective.

detail like a pro without the pro $$$
I've never detailed an engine bay myself but always knew it was something that should be done on a regular basis II remember STP made a product years ago for it but I don't know if it's still made. In the past I've always had the engine bay professionally done. but detailers engine degreaser allows me to take care of doing it myself with out spending the money to have it done. Well worth the price & allows you to detail the engine as often as you like.
Pros Quick easy to use, affordable allows you to detail under the hood as needed so it pays for itself
Cons If I could find a con it would be that it's not perfect but than nothing is to really get a show car shine you really have to spend the time to individually detail every component on it's own but the majority us are using it on daily drivers so that's expected. Plus I use it on a vehicle that's 13yrs old so your going to see the wear & tear that comes w/13 years of driving

DP Degreaser A++++
This is the best product ive used to date. Most aerosole based engine degreaser and cleaners dont clean better than this product. I also use this to clean my tools, hands and the shop floor when dealing with a greasy and oily mess. Highly recommend this product, i will be ordering more shortly.

Love tis One
This porduct makes it easy to have a very clean engine. It's easy to use and not harsh at all. The pictures of the Jeep engine used in the copy for this product belongs to me. This was the first time I had every truly cleaned an engine. Great results right out of the gate!

Powerful cleaning
This truly is a great degreaser, minus the harsh chemical smell found in every other degreaser I've used. Just spray it on a cool engine, let it stand for a minute or so, then brush surfaces to loosen dirt. Rinse, and voila! Crystal clean engine.
