It's been my experience that if it's stuck hard enough you can't break it by hand with a cheater, then no manner of oil is gonna touch it either. It's only after the fourth or fifth penetrating product I try, that I put some heat to it, melt everything that might be important nearby, put some more muscle on it, and shear the bolt head right off.

People don't do that PB, 'cause no one can stand the smell lol. I order it in at my shop, and not a soul but me will touch the stuff - at least until the WD or Seafoam Deep Creep run out.

What he said

Been using WD 40 forever. Cheap, available everywhere, and works great. I’m not afraid on it being a toxic chemical.. I have it on my bare hands almost every day. Never had any skin reactions with it. I spray small parts right in the palm of my hand. I’m not saying it you shouldn’t be more careful with open cuts, but I can’t tell you how many times it loosened bandaids on my hands. I’m close to 70 now and been using this product since its inception.

I did some fancy staterstics for your results: - WD-40 and Freeze Out have virtually identical errors thanks to that outlier - WD-40 and Freeze Out do not have statistically different breaking strengths (p = 0.84) - WD-40 and Secret Sauce do not have statistically different breaking strengths (p = 0.78) - Freeze Out and Secret Sauce are more different, but still not statistically significant (p = 0.33) - WD-40 and Freeze Out are both basically statistically significantly better than PB Blaster (p = 0.08 and 0.02) - Secret Sauce and PB Blaster are not statistically different (p = 0.35) - Cheating and removing the largest outlier from each set makes WD-40 and Secret Sauce have statistically different breaking strengths (p = 0.04), no real changes in other comparisons Just some fun numbers for the conversation. Hope you give us some more samples next time ;)

Did some statistics for yall (using MATLAB, all units in mV): Means +/- Standard Deviation: WD-40: 827 +/- 76 Freeze Out: 791+/- 78 PB-Blaster: 939 +/- 24 ATF: 866 +/- 43 Significant Differences (alpha WD-40 vs PB-Blaster: 0.031 Freeze Vs PB-Blaster: 0.011 PB Blaster vs ATF: 0.025 There is no statistical difference between WD-40, Freeze out, and ATF mix, however one can reasonably conclude that, assuming experimental conditions were constant, PB Blaster is an inferior penetrating lubricant. I'd like to know more about how you ensured uniform rusting and all of that stuff. Very very interesting work here, though, Ave. TL;DR: PB Blaster probably not great.

Another thing you can do is apply your penetrating lube and tappy-tap-tap with the handle of a screwdriver or other softer material. The vibrations *greatly* increase the capillary action of the penetrant and allow it to infiltrate the oxidation. Just like how your industrial vibrator causes particles to decrease their angle of repose (enginerding term!). Cheers, AvE!

Can you test the freeze off again but apply during the start of the test to see if the cooling loosens it.

I have my 3 jaw chuck stuck on my lathe spindle. I tried all kinds of things to get it out. My godfather recommended a few drops of eucalyptus oil and let it sit for a while (I previously let WD40 sit overnight on it too). While not a scientific test, the eucalyptus oil worked. Though maybe the WD40 had just soaked in further. Great test and thanks for sharing the test data! It makes me want to build my own rig to put other products to the test.

But the test actually produced one significant result: FreezeOut vs. PB at p=0.033, which is to say that FreezeOut is significantly better than PB Blaster when accepting an alpha error of 5% So yeah, I need some more friends...

I've always used PB, but whacked the bolt with a hammer and applied it multiple times. Sometimes heat. And really soaked the bolt in it. Maybe that's the game, it works if you use enough of it, and then you have to go buy another can.

Try the opposite. Put a torch on it. That really works.

As others have mentioned, Naphtha + ATF will mix fine and does just as well as using acetone. Hell you can add 1 part of each if ya want. Dexron II mixes *better* with acetone but because acetone is aliphatic, thats what's causing the separation, same as mineral spirits.

I use undiluted dot 4 break fluid on rusty bolts when even a torch and a hammer don't work. I stumbled on it when I was fixing break lines and needed to loosen up some small nuts that were looking like a solid mass of rust. Got the wrench on and broke the first one without much effort. Needing a lubricant and did not have any, I used break fluid and for some reason, the other three nuts just ... came off like new ones. Never tried it with acetone though but ethanol might work since blacksmiths dissolve flux (borax) in ethanol and dip cable in it before forge welding (it allows the borax to penetrate and reach better than water; water also can form bubbles of oxygen which is bad when forge welding).

Aerokroil is the best Ive seen. I presoaked my 23 year old bell housing bolts for several days. I only broke 2! I want to try secret sauce!

Kroil is always my go-to for stuck nuts. Maybe for a bit more of a real world test, drill and tap pieces of mild steel? Not sure exactly you would fit that in your tester, but that seems to me like it would be more representative of real world. never would have guessed WD would have done anything! Also, I would be interested in seeing how bolts stuck in aluminum are effected by these. I occasionally run across small screws stuck right stiff in aluminum, like motor end plates 'n stuff, and I ALWAYS end up breaking the darn things.

For the separation and application problems, I just bought a little $12 pressure pot sprayer and give it a little shake before applying.

As the results here showed, I've also had miserable luck with all of the "freeze" products and they're also all ridiculously expensive. Never liked PB either and I've tried it for years and years since everyone else raves about it. My longest term test of PB was applying it to some 20 year old brake lines every day a month in advance or servicing them. Lines didn't budge. Last weekend I did the same job on a different vehicle and 50/50 did nothing on the first side when I attempted to loosen it immediately, but worked awesome on the second side that had sit for a couple of hours while I was working on the first side. My major gripe with the 50/50 is that it makes a fairly huge mess since it's super thin. It also doesn't help, in terms of mess, that it comes out of the pressure pot like foam, but in application that may actually help it. Hard to really know for sure.

I've been meaning to try that nerve-killing fruit punch myself, as I suspect the evaporation acetone tends to do helps pull in the ATF; given that, I suspect a better way to do it is put acetone on first, and then immediately apply the ATF. I would also have avoided using the high mileage stuff, since that is supposed to help stop leaks, and the path down the threads has characteristics of a leak.

Good point. I would suggest using a plain old ATF too. Like ATF-4 the Mec/ Dex stuff has more friction modifiers to help the bands and clutches in the trans grip better, not what you want in a penetrating oil.

Yeah good point and DOG_REDRUM here also makes a good point here too about the friction modifiers. Never thought about that. It does seems to work though. I tried ATF and Acetone, although I use more than a 50/50 mix of Acetone to ATF. Like 70/30 cause I find the ATF is still too thick and it seems to penetrate better if thinned a bit more.

Control was the dry, unrusted fasteners.

Thank you so much. I love the videos. One important piece of missing information here is where is the results for your control group? As you know a control group would give you a better idea how effective putting an additive on is. The control group here would be four rusted bolts with no treatment.

I'll add to the chorus of heating then melting in some wax, as suggested toilet bowl sealing rings work great.

If nothing else works I heat it up with a torch. And if needed cool it down with something like what you have here. Doing a few cycles of very hot and cold works pretty good.

I've found that PB Blaster works best when you've got a lot of time to let it chooch. Give her a squirt and let her brood for a week. Only way to get a fastener off that has close to a century of rust and grime built up in the threads.

Apparently, one important ingredient is time! Yup, you have to plan ahead. At least a week. It also helps to give the rusty bits a little tappy-tap-tap and re-apply the PB every couple days - it helps with the penetration. Best is if you can put a little torque on the fastener WHILE tapping AND squirting. Then give it a day or two to chooch. If it doesn't come loose after doing this 3 or 4 times, then more serious techniques are called for.

As someone who does restoration work on old (1923 indian currently) bikes, I've found even a week of PB isn't all that great. No clue how it's gotten such a good reputation, maybe it used to be significantly better. What I've found to work the best is either knock-er loose ( www.crcindustries.com/products/crc/crc-knock-er-loose.html ) or if you can find it the BG oil product ( www.bgprod.com/catalog/specialty/bg-in-force/ ). The BG stuff is expensive but worth it, it comes out as a foam and seems to not just run off the side of the fastener quite as bad.

Also a tip for stuck bolts especially when its in cast iron such as an old engine block is to heat it with a torch and stick a candle (like the long skinny dinner candles) to it... the wax will melt and get into the threads and allow for easy removal. I know it works in cast.... not sure about other metals.

In NZ we have a CRC product that is Lanolin in a spray can. I bought it as a anticorrosive spray but have been very impressed at how it dissolves oxides. I left a cresent in my boat, salt water, la de da, 6 months siezed solid. Two days and its like it never happened. Only problem is it will not spray below 10c and sprayed parts smell like an aussie.

holly crap, should have read the comments first; Kroil is better known that I thought.

Do we have a control group? The numbers are interesting, but we need something to compare them to.

On farm as a kid i made my loosener from gasoline, diesel, and oil. The agitation / ringing helped a lot. Thanks.

nice job, was the bolts still cold when you tested it with the freeze out? It would be interesting to try heating the bolts up to different temps to see if there an optimum temp for Thermo expansion to losing the bolts

But... m'PB Blaster! I loves me that alien drool. Seems to work so much better than the usual suspects, and feels great when you get it in yer eyes. Tastes great too on those impromptu under-car snacks. Just wondering if the soak time had any effect. I think I might have dosed each bolt with schmoo while it was in the test rig, let it soak for a specific -- and realistic, given under-car impatience -- time, and then do the breakout test. As it was, not only was each solution allowed different chooch times, but bolts within a test group had variable times too. I doubt it'd make much difference, and you'd probably see obvious trends in the data if it had, but it just seems cleaner to eliminate the soak time as a variable.

Something that has "freeze" in its name suggests a thermal action, which gives it a relative advantage if there isn't a soak.

I'd love to see a control of fully rusted bolts with no assistance. Just to know how much of a difference the products are making at all.

I also have spent a ton of time laying on my back, wrenching on on the gnarly side of GM's finest steel ravaged by Michigan winters and salt trucks. Not having an impact, and relying on the smallest muscles in my forearms while contorted like a pretzel to generate torque; I've found through my experimentation that alternating meager amounts of heat, PB Blaster, and occasionally some coaxing with swear words and a hammer would break most things loose eventually.

Dad always used a mixof atf and break fluid. Worked great on hit miss engines and his old model t

What did the rusted bolts break away at with no shmoo?

If a bolt refuses to give up its nut. You must have the proper lube to effect its release..

hey you how long have u wanted to say that

The stuff at the propane plant I worked at was Free All Seemed to work, very oily and a smell you will not soon forget. Much like propane actually. That said ancedotally I like the 50/50 mix, I usually use a gun cleaning solvent called "Ed's Red" which has a couple other things in it. That said, I heat the crap out of the part typically before applying if it's that bad.

I've always had stellar luck out of ATF 50/50 with seafoam. It doesn't seem to separate like the acetone and never fails to break stuff loose seemingly better than anything else I've used. I've also heard good things about the Seafood Green Stuff or whatever it's called. Haven't used it personally, but know some guys that swear by it.

I suspect the results would be different depending on how long you let it soak. The funny thing is that I've never had any luck with normal WD40, but their penetrant formula has been OK. PB Blaster has always been heralded as the second best to either mixing your own or Kroil, the whole solvent/lube thing (put it in a plastic or styrofoam cup and it will dissolve it) and I've never seen good results with it. I've had OK luck with ATF/Acetone, but I can't seem to keep it in a bottle that is convenient for application. I did some research and found that those plastic laboratory type squeeze bottles with the plastic tube sticking out the lid should work, mixed some up and left it sitting on the table of my bridgeport- a few weeks later I found the bottle nearly empty, the bridgport table full of the stuff and no noticable hole in the bottle... it was weird.

I suspected the same but I'm pretty sure that's not the case. Again, it was sitting on the mill table and was down in the ways. The only stuff on the table was right under the bottle where the bottle bottom lip was sitting on the table. For it to have been vapor pressure pushing the stuff out it would have come out the tube, run uphill up the tube and then down the bottle, which I expect is near impossible. I have another oiler that came with one of my lathes that I might try (similar thing but smaller, and the tube doesn't go all the way down into the bottle so you have to flip it over to use it, but this one is full of Marvel's Mystery Oil which seems to work as a pretty decent penetrant, cutting lube and it smells nicer than the rest of this stuff (not sure what that stuff is made of)

Did the tube go down to the bottom or at least into the oil? If so that would explain why with the pressure of the acetone

liquid wrench ? Ive use it manny a time and it works well imo

Aerokroil and Kroil tend to be the choice here. Best luck with ATF/Acetone mix is usually in a sprayer (old 409 bottle) where you can shake it as you use it, worst part about it is I never have Acetone laying about.

For the tough stuff at our shop here in Oregon We use straight Liqui-Moly Fuel injection cleaner and sometimes Hoppe’s # 9 gun cleaner. Give it a try See what you think

KROIL is suppose to work great. Please test.

I recently got told to blowtorch then push an old candle onto the threads. Worked for some exhaust bolts that were mocking me.

Ben Carter yep works great, I keep a toilet bowl gasket in the shop at all times for those real tricky bastards. A little heat and a little wax goes a long way, repeat as needed until successful. Hasn't let me down yet.

I’ve noticed that dex3merc mixes the best with acetone, and other dex4, dex5, ford atf, etc don’t mix as well with acetone. The others separate far quicker and don’t lubricate nearly as well. Since dex3merc is very similar to aw-32 hydraulic oil in viscosity, I wonder how an artic blend hydraulic oil with aw 5-15 viscosity would do. Very frequently I apply the 50/50 mix, heat slightly, and reapply with very good results on dirty fasteners. This works very well for brake line fittings that are almost always corroded in the threads and to the steel line itself.

Hi, love your channel! I got a tip from a mechanic once that used regular water on rusty bolts. He puts the water on with a brush and leave it over night, according to him that worked really well? It would also be interesting to see four unprepared bolts as a control group, to see if the chemicals did anything at all? /snowy greetings from Sweden

The Mrs. says they feel the same.

Check out corrosion-x, that stuff is amazing. I use it every day at my job at the naval research laboratory as damn near everything we have gets covered in rust very quickly (my test site is 20 feet from the ocean)

I'd be curious to see a proper control test. Also how each does when heating the crusty fastener first. I use PB most often but always with heat first where possible. It seems to help, but I think it's a heat/cool cycle or two that lets it get into the threads.

Would like to see Fluid Film and Boeshield T-9 tested. Both are sold as a lubricant and rust preventative as well. They are not sold as penetrating oils to loosen parts, per se, but would be interesting to see if they do.

How do you explain the control being lower than almost all the other tests? Seems like something odd is going on there. Probably should have had 4 controls as well and gotten the average. I'm also wondering if the PB you guys have up in the Great White North is different from what we have in the states, because I've had great luck with it.

Says dry, I'm assuming it means no penetrating fluid. He was handling two rusties at the beginning and talking controls, need to review. Well I thought I saw him handling two rusty bolts before the control test, but, at 3:00 he flashes up "Dry, rust-free threads". So, I don't know what I was looking at. So, we have no idea where the un-treated rusties would let go.

You need to add Fluid Film and Krown Fast Acting Penetrant to the next series of tests, and also do a proper control with the same amount of rusted fasteners with no canned assistants liberally applied. Would also be nice to see a comparison between say 10 seconds of wait time vs 10 minutes and maybe even 30+ minutes after application of each product. Fluid Film is pretty impressive multi-purpose product. Lubrication, rust prevention, and rusty fastener medication. I haven’t used PB blaster in a long time. It works but I’ve always needed to liberally apply it and let it soak for far too long to be useful to me, or add heat. Fluid Film and Krown products have changed my Go-To can grab when a rusty bolt needs to be taught a lesson.

I highly recommend using CRC brand Freeze Off, It may be similar to the gumout stuff you used... I'm a mechanic and when you need to take a rusty rotor or drum off a car the CRC freeze off with straight up break them loose... I haven't tried using it on stuck nuts etc... but for rusty rotors it works.
