Autozone, checker and o' Reilly's are all owned by the same company so it makes sense they are the same chemicals.

This is AMAZING! You should have a million likes for such a thorough, scientific analysis!

I also love your channel, I found it yesterday and haven’t been able to turn away from these product comparisons! Thanks!

Suggestion Try your test on heat baked grease/oils. Just like on a engine block

Motor Medic doesn’t sell that degreaser anymore. It’s a rebadged can of Gunk original. It was cheap because there’re just getting rid of inventory. Anyways I looked up the MSDS on the Gunk original and it’s pretty much 90% Diesel and 10% Kerosene.

Great report, Repair Geek! Excellent research as far as I can tell. Keeping as many parameters constant as possible, comparing performance objectively, and ranking on price if needed. Well done. I am so grateful! And telling how it is, i.e. using just diesel and kero to improvise, proves you're not tied to any manufacturer or brand! Really rare these days, hope folk recognize this! I, as some others, of course, we all would want to see more: e.g. how do these products perform on "baked-on" oils and grease. Hey critics: if you don't find people who do it for you, why don't YOU do it and publish your results? Merry Xmas, Matthias.

Thanks for doing this! Really appreciate this and the brake parts cleaner. One that I would be curious about is Schaeffer Citrol and how it fits in.

Very useful information. Thank you! Please keep making videos.

RG, great, practical review. Concise and clear. Thank you.

Great post! I have 4 motors to degrease. Olds 350, chevy 350, 454 and 305. 3 on the stands and 1 in the car. Overwhelmed by the task and potential cost. This helped out big time!!!!.

I just used gunk on my old truck...did spray with water or anything, I wiped with clean clothes & was very pleased...the grease came of. However, I like your tests and will test others,too. Thanks for your efforts!

Can't thank you enough for doing these tests.

great job on the video! keep up the good reviewing!

I totally agree, back in Europe when i was little all the mechanics would wash dirty motor parts in a 50/50 blend of gasoline and diesel

A motor would bake all that grime on. But I love that you did the 24-hour test!!

Excellent video and I like how you tested more than just the effectiveness of the cleaner but also it's effects on different materials that it may come into contact with. That said, I'd like to address a couple possible flaws in your methodology. First, I would have primed the test pieces and allowed the paint to fully cure in order to more accurately simulate an automotive finish. The difference in hardness and adhesion between a one day old paint job and a one week old paint job is staggering. In all likelihood, none of those degreasers would have even dulled the gloss on a primed and cured paint job. Second, I would have followed the manufacturers instructions for the use of each product. Settling on a 5-minute working time for all products really only makes sense if the end user is the type of person who's going to let it sit on there for 5 minutes, regardless of what the instructions on the back of the bottle say. Those people are dummies and I feel safe in saying that because they're not here. Anyone watching this video is going to follow the directions on the back of the bottle. That's why they're here, they're intelligent, inquisitive and they want the best results. Third, I would have baked on the grime slurry. That stuff's not hard to remove just because it's inherently sticky or sludgy, it's hard to remove because it gets baked on. You don't have to hit it with a blowtorch, although I suspect that would remove a good deal of it in itself, but a couple 1 hour sessions in the toaster oven at about 200°F would have really done the trick to get it good and stuck and would've more accurately represented real life under the hood conditions. Again, great video. I look forward to hopefully seeing an updated version of these tests.

Cool video. I use super clean all purpose cleaner degreaser mixed at 2:1 with water rather than anything in a can.

Great job again! I couldn't find any of the Motor Medic in stock anywhere. Another poster mentioned that MM doesn't make it any longer. So have to go with with the Gunk...but I've been using the Gunk for a long time so it's an old friend. And you're right ... it definitely is stinky.

Super Clean foam would have ranked #1 (by far) if you'd tested it. Extra benefit to it: it's VOC free and biodegradable.

I deal mostly in baked on deposits and the gel type Gunk Engine degreaser is top notch and Easy Off oven cleaner seems to be even stronger.

Great review!

diesel and dunk 50/50 mix, the gunk allows the mix to rinse off, or diesel first then gunk. Orielys used to be dry cleaning fluid,, works great for stains on clothes.

Great job...well done😊

Thorough, love it, thank you!

Thanks for the reviews...If I can find the motor medic :boom, The Gunk is next...:)

I used to use a cheap kerosene based cleaner when my engine was pretty dirty then I'd use simple green to maintain.... thanks for the test

I want to know what works on real, old world, engine block and other frame surface like I have under the hoods that I own or work on. Thank you for your video and the information you shared here! Many good points and much information but not much benefit for cleaning OLD crap off an OLD engine or surrounding frame work. I still give a thumb up.

You guys are missing one important detail , yes these degreasers have diesel and / or kerosine but they also have an emulsifier so that they will disperse or can be “rinsed off” with water. That’s why it turns white when you rinse . Not sure if they still sell it but Gunk used to sell a concentrate that you could mix yourself with solvent or kerosine or diesel.

Brilliant video

Purple power and oven cleaner would be interesting to test

I never felt like that stuff helped much it seems like the pressure washer is doing almost all the work

Mighty Boss is great. I get this shit called Tornado 50 from St. Albans, WV. It beats anything I've ever used. Have a nice day.

Wish panels had been heated before trying to clean...also like to see heated bare cast aluminum. Have a pulled aluminum LB that is caked in oil. Pressure washed with hot water and trying to clean and so far only used strait simple green but going to get the Pro HD SG. Also going to try fast orange on it as what I have. B12 works but evaporates so fast and not trying to poison yard so something like SG or Dawn be ideal. Either way TU for vid. Thanks! ...edit Dawn ended up working best as initial cleaner. Have to brush using small fingernail like cleaner brush and toothbrush but want it as clean as possible before teardown.

Great videos great job thanks repair geek

@@katiedotson704 I cleaned my 1st gen Tundra engine bay a couple of weeks ago and used a process similar to the Chris Fix method (he has a good video on it) to make sure I didn't hurt anything. It's not complete as I had a leaking valve cover gasket that has since been fixed. Mostly I used the warm soapy water so far, but now I'm going to go back and finish getting the oil from under the valve cover area and down to the manifold. I'll use a degreaser and then warm soapy water to get the bottom areas. I cleaned all the items I could reach, painted areas, plastic, and metal and then shined each one with non greasy plastic protectant, waterless paint wax or a bit of Mother's chrome silver polish or a wire wheel (each cleaner to its intended area) ... and the results are very nice, it looks so much closer to the engine I remember from back when it was new. No mechanic spills or road grime, it's not perfect but wow it looks so much better. Next time I'll get some longer reach brushes to get the parts out of my reach. Us girls have to work a but harder to get to everything under the hood it feels like, but that's OK, a reliable and great looking truck is worth it. I even replaced the cold air intake system and cleaned the throttle body while I was in there and will be replacing the spark plugs this week. 149k miles is just warning up for a Toyota 🙋‍♀️💖😊

@@FreedomLovinLady My 30 yr old girl just turned over 300K. I rebuilt the starter last year and at this point I have the alternator on my bench. I should have already had it back on but the thought of scrubbing, sanding, and painting it came to mind. I had almost talked myself out of it til I found out there is a paint color called Cummins Beige. Now, I couldn’t turn that down. Then one thing led to another. I don’t know if others think it’s a good idea, but any time I replace or repair a part that is external to the engine, I use a paint pen and write the date and mileage on the part for future reference. I’m changing the interior color and am planning on taking the dash cover out to paint it after alternator gets back in. I’m trying to talk myself out of painting valve cover but I’m pretty sure I know how that’s gonna go.

Try paint thinner or varsol in a spray bottle. Better than all those commercial products and won't damage paint a bit.

Thanks Dude for your test

You can actually do the same thing with regular ol wd-40 its a patroleum based lube/rust breaker and almost immediately devolves grease. But it also leaves a greasey smeary finish Best to just leave it soak in then hit it with a power wash or hose But engine degreaser and oven cleaner do ok too lol

Kerosene and wire brush is what we always used and it always worked

What about on a heated part/engine. Does heat activate the claning chemicals to clean better?

great vidio, but i use diesal mixed with simple green

good job.

many thanks! but you get to use a table at last for summary!!! you seems missing supertech in your list,

Will be nice if you line them up the cans to see them well

45 years ago at the garage that I worked at, used kerosene in their Safety-Kleen parts cleaner bath. The owner wouldn't spring for the Safety-Kleen brand cleaner.

Not exactly a revelation thar acetone and kerosene works well dissolving oil and grease. Would like to see a part 2 with only non-VOC degreasers, including Bilt Hamber Surfex HD.

Pretty sure you used oreillys spraying clip for the autozone comparison? So oreillys is better?

K2 AKRA 770 ML (K177) - engine cleaner nothing beats this

Yeah, super tech spray is trash Bought some because it was $1.50 cheaper than Gunk when I was at the store. Not only did the product not do anything, it screwed up my painted valve cover like yours showed. At first I wondered if it was always like that, but when I rubbed my hand on the back side of the cover it was perfectly smooth where as it felt, and looked bubbly on the front and sides =/ This upsets me, wish I new before hand lol

So with the O'Reilly just make sure you rinse it off good then it won't do anything to the rubber just don't let it sit 24 hours?

What's not safe about diesel or kerosene? Gunk directions say to spray down with water after

wish you would have added BLACK MAGIC engine cleaner

I think giving an average time to all the brands was a mistake because of different formulations have different consistencies which would effect the test results. After all your testing which cleaner cleans best not what's best in ten minutes.

Should have put some dirt in there most oils that build up have dirt that makes it cake like it does

Where do you buy the Motor Medic? Newk from Kentucky

I wouldn't want to spray the kerosene diesel stuff on anything under the hood. Yeah, it will clean. But dirt sticks to diesel and kerosene very very well. The next cleaning is going to be a duzy..

mineral spirits works well also

Just a suggestion, easyoff oven cleaner and simple green. Also, try baking these at about 500 degrees for 30min to make it harder.

Autozone I believe.

So moral of the story is the old timers using kerosene and diesel had it right the whole time

It would have been more accurate if u followed the directions on the can. If it says 2 mins then do it for 2mins. The manufacturer put those instructions there after they did their own timed testing to find how the product works best.

I always used old gas as a degreaser, so all the crap on the shelves is just to scam you out of you hard earned money. My mom used to clean the windows with newspaper and vinegar, 10 cents to clean the house. I will try that next time, Windex seems to leave a film.

It is the dried on grime that is the problem, less stuff & add some dirt leave it to dry, then you will have what you get in an engine bay!!!!!!

No brush and actually bake it on....just like your engine does.....huge difference
