I saw a youtube video a few years ago where somebody tested different penetrating fluids, and a concoction of 50% MEK and 50% ATF worked the best and penetrated the farthest. I've been using that formula for years in a refillable sprayer, and it's been working great.

[@johnclamshellsp1969]

The only issue with Methyl Ethyl Ketone (MEK) is the cost. That stuff is selling for about $35 a qt.

[@ferratilis]

​@@johnclamshellsp1969 I just recently got the real MEK, not the substitute, at a paint store for $35 for a gallon.

[@Killianwsh]

50/50 Acetone & ATF also works like magic! I will NEVER go back! You should try it! It's MUCH more effective than WD40 for freeing rusted in bolts!

[@jonasjonaitis2949]

But its more expensive isn't it ?

[@Gieszkanne]

Aceton is very agressive on polymere and varnish. Also Acetone dont disolve mineral oil as good as mineral spirit. Dosnt sound like a good combo.

[@Killianwsh]

@@jonasjonaitis2949 Sorry for the delay. just saw your question. The answer is : It depends. If you are buying the components expressly for this peoject, the lghter fluid & mineral spirits may be cheaper than acetone. But if you already have some acetone you use for other projects, acetone & ATF will be cheaper. Personally, even if the acetone & ATF was the same price as WD-40, I would still buy it, because it works much faster with MUCH less fluid used. I literally apply the Acetone/ATF mix with a blunted medical syringe.

[@Killianwsh]

@@Gieszkanne Well I've never had a bolt get stuck in mineral oil. While Acetone may be very aggressive on primers and varnish, 99% of the bolts I've ever had to use any penetrating compound, like WD40, on have been far enough away from paint & varnishes that it wasn't an issue, or the rusted bolt/nut could be shielded to prevent over spray of even the resolized mixes. TBH, I don't know the specifics as to why the Acetone & ATF work the way they do, but can state that, in my experience, it works much faster with MUCH less fluid used than any other mix, commercial or home made. I literally apply the Acetone/ATF mix with a blunted medical syringe directly to the threads of the bolts where they mate up with the nut and the majority of the mix is wicked directly into the threaded mating surfaces. Almost no spillage, unless I've been sloppy, and even then, the acttone flashes off so quickly that, by the time you grab a rag, you're just wiping up a couple spots of ATF.

Ilike that your videos are short and to the point with no jibber-jabber or phoney baloney.

Thanks man! I try to only include the important stuff but sometimes it’s hard to know what to keep/delete so this feedback is valuable to me. Appreciate it!

[@maxironpaw]

@@sweeneyoffroad I'll cite your alternator welder vid as as example. You concisely presented just the right amount of theory and practice. Other channels would have drug that out for 45 minutes or more.

@@sweeneyoffroad Hang in there, brother, you're doing fine.

[@wolfparty4234]

No way maaan!! No hater here! I think it’s great that you made this video for us! One day many years ago there was a man just like you working on junk cars and trucks that said to himself “ I wish I had something that would help brake these rusty bolts free” and boom one day, WD-40 was made then sold! Maybe you could market your with your name on it💪🏼🔥🔥🔥🤣👍🏻

[@DiffEQ]

That's nowhere near how WD40 came to be. Not even close.

[@TopCat2021]

Nice concoction I'm going to try that for myself and I'm also going to try a mix with ATF to see how that works as well.

[@cam3002]

Brilliant, I'm now subscribed. I will give this a try.

[@sweeneyoffroad]

Thanks man! Let me know how it goes!

[@markifi]

now to find european equivalents. woiuld 4 isopropyl, 4 odorless mineral spirits, 1 chainsaw oil work just the same?

[@cyndisoo]

Thanks!

[@jamesduffus4455]

I've been building and restoring cars and machinery for almost 30 years and one thing i discovered works better than WD as a penetrant is SAE DOT3 brake fluid just keep it off paint.

[@sweeneyoffroad]

Good tip! Thanks for watching.

[@DiffEQ]

SAE DOT 3 is corrosive and hydroscopic... meaning it is the very WORST thing you can use as it actually absorbs water vapor from the surrounding air. SMH

[@brianlavigne3579]

How flammable is it compared to real WD40?

[@dodge_ute]

I use Kerosene to loosen rusty nuts/bolts. A one litre bottle of Kerosene/parrafin (a very light oil) was $2.50 and a squirt bottle was $2. I don't claim its as effective as WD40 but works for me, that quantity lasts for ages and the price is right :)

[@ttyger1]

I cant put air pressure in that can, can i just oit it in a heavy duty spray bottle? Does it have to be under pressure?

[@johnclamshellsp1969]

Great videos as always and thank you for the WD40 homemade version. Dollar for dollar, yours is the cheapest.

[@DiffEQ]

Only if it works as well as WD40. He showed nothing about its efficacy.

[@johnclamshellsp1969]

@@DiffEQ I don't make videos, but did make small batch of this. Can tell you 100% or better it works amazing. Had a grossly rusted #2 02 on a cat converter (2009 Hyundai Sonata). Soaked PB blaster no affect. Tried actual WD40, no effect. Tried the homemade version and worked in five hrs. The homemade version is thinner, and it made it through the threads. Had no galling on cat or threads of O2. Also, rust was coming off old part and almost down to sorta clean metal. The sensor was original to 2009. John A 60107 USA.

[@stephenwhite5057]

I use a similar mixture under my off roader to keep the rust at bay.

[@DiffEQ]

I like that you get right to the point and don't fumble your way through the video. But, bow much WD40 does a typical person use? And when you buy a can of WD40 you get the aerosol applicator and don't need to spend the $60 plus tax on a Sure Shot sprayer. Using your numbers, you'd have to use nearly a gallon (99.98 oz.) of product to break even . That's eight cans of 12oz. WD40. Most people would take a lifetime to use that much. Showing how much it spreads doesn't demonstrate its efficacy. BTW, keeping a cutting tool cool and sharp is best accomplished with a more viscous fluid like the very oil you added to your "home brew". If you DO use that much WD40, a 5 gallon can is $128... works out to 19¢/oz. no hassles and its efficacy is KNOWN.

[@JakePlisskin12]

yeah i was going to say i very rearly buy spray cans anymore , i just buy the gallon cans and put into micro spayers. im 35 my kids will probably have to finish it off figureing out that you dont need the amount you think you need.

[@guywihn1658]

WD40 has a lot of wax in it and is what you see settle on the bottom when you purchase it in a clear gallon jug, and also why the instructions tell you to shake before use. It's to bring the wax back into suspension. First and foremost WD40 is a water displacing product.

[@swavacadoo]

Time to spring clean that shop :)

[@sweeneyoffroad]

No doubt!

[@azurplex]

Nice penetrant recipe. WD evaporates and doesn't leave lubrication behind. Yours will, so it may be better or not depending on the application. Perhaps it mimics some of the other products on the market.

[@Gieszkanne]

WD does leave lubrication behind. At least the european/german version.

[@DavidinTexas]

Instead of lighter fluid, i use grain alcohol, or 'left overs' from the still... my friends all HATE the taste of lighter fluid on the BBQ

[@JEEPLIFE121]

Try switching the motor oil for transmission fluid, transmission fluid is a lot thinner than motor oil

[@sweeneyoffroad]

Might be worth some experimentation to find the best recipe!

[@rfisher79]

Aerosol WD-40 is Water Soluble... I made the Tools and Dies for the Spray Cap with the New Bendy Straw. I believe you made Kroil or PB Blaster, please do more research.

[@sweeneyoffroad]

What makes you say WD40 is water soluble? It is not. WD means water displacement. The oil in WD40 would not allow it to be water soluble.

[@DiffEQ]

Wrong! WD40 and water are NOT miscible.

[@Buzzardlead]

What is that sprayer called and where can I get one ? Great presentation !

Wd40 doesn't have oil in it and it evaporates quickly. The concoction you made is the opposite. Idiots don't read the wd40 label, its not a lubricant and its not a rust inhibitor

[@sweeneyoffroad]
