How do you guys apply the acetone/ATF mix to a rusted fastener? Anyone ever try one of these refillable aerosol bottles? https://www.amazon.com/dp/B009IY6IHS/?tag=atomicindus08-20

I spray it or soak a rag strip in the mix and wrap that around the fastener.

.... but dang, that has possibilities!

I like the crc freeze off. It helped remove the crusty bolts so frozen that even standing on a breaker bar with a 4 foot extension wouldn't remove. However I'm willing to try other things

Seafoam Deep Creep seems to hold up better when used along with heat. The heat helps oil flow into the microscopic gaps to free up that stuck fastener.
But I'm another fan of Kroil. Got mine on the two for one deal. One can lasts a long time if you don't need to soak something big. For that I too use the 50-50 ATF and Acetone.

Anybody out there use an induction heater?

Yep I have one. Have had it for several years and needed it today but forgot that I have it and it will heat up a piece like butter. I got mine when I needed to get a bunch of sealer out of a floor of a car (bodyshop years)

 

[don long]

I, ve never heard of this 50/50 mix before nor have I ever found kroil and this is what I had to use today.
You got to love the Gj I learn new stuff all the time
Thanks guys

I just ordered the 32oz Sureshot to use for this.. or maybe break cleaner.

JonnyMac, think about what you wrote. I know of no corporation in the world, whether it be in OZ or America, that gives away money. If they are willing to spend that kind of money for it don't you think there must be a reason. If something else were as good for 1/50th the price would they not use it. Here in America Kroil cost $53 a gallon which in my experience is a lifetime's worth of Kroil. Personally, I consider that to be dirt cheap. I've been using it since by dad stole a can of it and a Kroiller (their pump oil can) from work in 1970 and I'll be using it until I'm dead. I've been using the same gallon since 1980. It's true that I live in Arizona and rust isn't a big issue here but I'm originally from Pittsburgh, PA where it is and I've still got a quart left in the gallon I bought in 1980. Why are we discussing pennies?

Not quite sure what your angle is.. itz a fairly simple explanation as to why i havent used it...
Take a deep breath and maybe have a nap.
Pretty sure most people would find $120 for a 300ml can a little on the expensive side

I thought that acetone/ATF study had been revealed as a hoax? Typing it now, though, I can't find anything to support that recollection through Google. So I could be off base.

 

[67King]

This discussion happens here about once a month and I'm always amazed by the guys that refuse to pay for Kroil (which I feel is cheap considering what it does and how long it lasts) but have no problem paying for Snap-On. Seems illogical but that's just me.

People are funny. Will spend $20,000 on a race engine, but won't spend $20 for a liter/quart of good, high quality race oil to protect it.

I use a spray bottle. they used to sell them to refill with WD40, so it can handle the solvent. regular spray bottles quit working after a few pumps...also old school metal oiler cans, the ones with the adjustable tips work best.

 

[dnschmidt]

JonnyMac, Understood. All I'm saying is that clearly they are willing to pay this insane amount of money for it, I'm not suggesting that you should. As I stated here in the US a gallon of Kroil goes for $53 directly from Kano Laboratories. That I feel is a fair price and worth every penny considering how well it works.

+1

What I don't understand is all the discussion about it... buy a bottle and try it out. Were only talking $20, if that. That said, I mostly use PBlaster and if that doesn't do it... impact and/or heat.

 

[clubairth]

I am Kroil guy too but just try the Acetone/ATF trick.

It works shockingly well! I use a very small plastic squeeze bottle that only holds about 1 oz. Has long neck on it so I can drip the mixture on the trouble area. Let it work for a bit if you can.

[dave*99]

I currently have Kroil, Spray Solvo, PB Blaster and Freeze Off on the shelf. I have used all of them for years. IMHO Kroil works the best.

 

[Handyfarmer]

plain old diesel fuel works good as well,

I at one time was buying cans of penetrating oil, from a leading tractor manufacture, (paints there tractors red) and I would swear that all that was in the can was diesel fuel, (or kerosene dyed red)

Don, I wish I could just come hang with you and help you work on some of your projects, you always have something going and seem to get a lot accomplished.

I've seen this potion and variations of it on gun forums for years and it's still recommended. Google "Ed's Red bore cleaner".

 

[jeffmoss26]

I swore by PB Blaster for a long time...it's made here in Cleveland...as soon as I discovered Kroil I never looked back.

Doh! Ed's red, I posted about Fred's Red...thanks for clarifying...

 

[GRX]

CRC 5-56 used to be my favorite. Has not been the same since reformulated in the early 90s though. Kroil is good. PB'laster is a close second. An old Plews trigger oil can of 50/50 ATF/Acetone is my go to now. Nice and cheap, and it works! Have to shake well before each use as it does settle out.

With prices (prob 2007 prices):


"The April/May 2007 edition of Machinist's Workshop did a test of penetrating oils where they measured the force required to loosen rusty test devices. Buy the issue if you want to see how they did the test. The results reported were interesting. The lower the number of pounds the better. Mighty interesting results for simple acetone and ****** fluid!

Penetrating oil . Average load .. Price per fluid ounce
None ................. 516 pounds .
WD-40 .............. 238 pounds .. $0.25
PB Blaster ......... 214 pounds .. $0.35
Liquid Wrench ... 127 pounds .. $0.21
Kano Kroil ........ 106 pounds .. $0.75
ATF-Acetone mix.. 53 pounds .. $0.10

The ATF-Acetone mix was a 50/50 mix (1 to 1 ratio)."



Also, another trick which I haven't tried yet is to heat the parts and wick candle wax into the joint. That's supposedly another slick trick.

That's why you should always wear nitrile gloves when handling acetone. Sure its dangerous but that's why there's ppe. I guess if you're a child about it you shouldn't handle acetone.

You actually want to wear latex gloves with acetone.

Glad you mentioned that.

Nitrile is good for most solvents, but Acetone is definitely not one of them. Best for Acetone is Butyl rubber, followed by Latex which has a 10 minute "break through" time limit.

[edit]:
And yeah, I have a both nitrile and latex disposable gloves in my workshop. My significant other is a nurse and she gets boxes for me free.

 

[toolsRme]

Kroil is the best IMHO but if possible I'll take the work piece to be treated with Kroil outside to avoid a stinky shop all day. If that's impossible I just spray away and open a window - BUT the stuff works!

 

[1990 Grand Wag]

I have a can of the AeroKroil that someone gave me to try out. It works pretty good, but I'm not going to sit here and type up a lie either......................that 50/50 Acetone/ATF mixture works VERY well (IMNSHO)!!!

 

[bonneyman]

The 50/50 mix above has done wonders by me.

 

[Justanoldguy]

Gibbs Product has always worked well for me.

 

[Ed ke6bnl]

I think I am done watching these penetrant comparisons and will just stick to the homemade version and now make my own WD40 like solution from the internet just made a gallon. the only magic in the store bought is your disappearing money.

I have had that list hanging on my bulletin board since 2009
In the shop: I have a couple cans of Kroil, a case of PB Blaster, and a gallon of WD40. There is also a can of Acetone and a barrel of ATF..

Liquid Wrench is an old favorite going back over 50+ years..
add plain old fuel oil to the list.

If needed, I have the choice of Marquette, Forney, or Smith

 

[chris142]

We use a product made by zep that uses soybean oil. Sprat it on and wait a few minutes and usually things will come apart

 

[Pipe]

How come a company doesn't sell 50/50 and just name it something?

 

[M6erfan]

Dang! There goes my million $ idea...

 

[M6erfan]

For the high volume user the homemade makes sense. I buy AeroKroil on special and 2 cans last me well over a year in my home shop, and I like the aerosol better than a pump can...

 

[kev b]

I live in the UK and as far as I know PB blaster and Kroil are not available here.

The WD40 we have does not seem to work as well as it did either.

Anyhow I had a friend turn up in a Citroen with alloy rear callipers secured with two long steel bolts through the alloy, into the cast steel suspension arm. Everything was corroded up really badly and one bolt had sheared in situ, the rest were immovable.

Previously I would have used oxy acetylene or waited days whilst wd40 soaked in but I was in a hurry and decided to try atf/acetone, wow! it really did the trick.

I read about this ages ago but never bothered to try it, I am now a convert, any doubters should at least give it a try.
