This man still replies to comments after 2 years... that’s awesome 👍

I work at a hardware store that sells a lot of the products you test. I’ve actually been referring unsure customers to your videos to help them decide what to get. Absolutely love your channel!

Yikes, Liquid Wrench is now $12 a can. PB Blaster is $6. Your video drove their sales and price I bet! 😂

I've been in aviation maintenance for over 20 years and 100% hands down prefer Kroil to just about anything. I'm a little shocked to see it perform poorly on this test. It's amazing on dissimilar metal corrosion and heat stressed titanium, which are often found in aviation. It also smells great! Thanks for your videos. I found your channel a few weeks ago and have already purchased a few products based on your testing. I am not disappointed!

This guy is either a manufacturer's worst enemy or best friend.

"Results: Liquid Wrench came out on top, following by ATF/Acetone, Royal Purple, WD-40, PB Blaster, and AeroKroil." Thank you very much for typing that in the description!

I enjoy watching your videos for numerous reasons. I'm a mechanic & have been almost all my life & there are many methods to removing frozen or rusted hardware. ( 1 ) PB Blaster is JUNK & the product often runs out of Aresol leaving over a 1/4 remaining in the can. RESOLVE: I use a AC puncture handle & empty the remainder into a spray bottle. ( 2 ) WD40 is JUNK- Over time if you do a test, you'll find that the surface of the stuck / rusted whatever will get much worse, especially if left out in the elements. RESOLVE: Don't waste your money! ( 3 ) Gasoila - Works great but only if you have time & soak the problem repeatedly, that's with most other products. ( 4 ) FreeAll - I've used it a few times but it's VERY expensive & honestly doesn't provide a value at all. ( 5 ) Liquid Wrench - In my opinion & the millions of time I've used it is MUCH BETTER than all the other brands. As for the cost, it depends on where you can get it. I've found with most that if you have time & consistantly keep soaking it that almost any product is better than none. The conditions & temperatures & exposure all play a part in the demise as well. EXCELLENT CONTENT in your channel & like your content providing answers to those whom wish to learn & gain knowledge! THAN YOU SIR 🙂

Here I was using Liquid Wrench all this time because it was cheap, and was considering the 50/50 mix... Nice to see LW placed so well, I'll be sticking with it (wasn't thrilled about playing with acetone). Thanks for what you do, subscribed!

Nice job! You forgot a big piece. The control step where you put a wrench on an untreated nut, apply full strength, slip, skin knuckles, and then proceed to mumble choice profanity.

I hope you never get tired of doing these tests. As someone with both limited knowledge and funds. It's easy to be lured to buy the "best" (Most expensive) . I'll take function over form every time. Your channel helps.

Also, worth mentioning is to heat the nut and not the bolt. The idea being that the circumference of the nut will increase and separate from the bolt and break the 'seal' formed by the rust/etc. Yes, the bolt will get hot and expand as well, so if you've never done it before, heat the nut for a bit and then try to remove it. Lather, rinse, repeat.

Only 4 years after the posting and I watch this video, but really entertaining. I just wanted to share that a product I've been using for years and love over anything else I can think of is called Tri-Flow. It comes in a black and orange can and when you shake it there's a mixing ball inside the can similar to what you'd hear when shaking a spray paint can. Thanks for all the hard work you do Project Farm!

3 years later and your video is still helping people find products that actually work. Thanks!

Keep in mind he's testing these products on short-term surface rust. It's going to be a different story on years old, very rusty fasteners you'd find under a vehicle. The fact is sometimes a torch is the only solution and that's why I always have one on hand.

Man I really appreciate you putting in the time and effort to do these videos. Very helpful!

I've watched this video a few times over the years, but can never remember which to get. I came back morning to make I linked from your video. Keep up the awesome work.

It's really satisfying to see how consistent you got that rust. It's almost beautiful!

Hats off to your channel for no click-bait

He's come such a long way. Love seeing the progress in techniques and ideas Awesome channel and thank you for existing and waking up every morning 🌄

Awesome presentation and review of these products you are the absolute best at these types of products reviews. You show no actual bias and only tell the outcome of your tests and they are done super professionally. And your English is spoken clearly and understandable and you only use words that the average layman can understand. No big fancy words that are not understandable. Thank you for your awesome presentations and hard work.

Highly underrated KZfaq channel. Thank you for your content and time the time taken to make them.

I am literally watching this while standing in the hardware store looking at the penetrating oils.... Full volume on my phone and giving you a thumbs up! 👍👍👍👍👍

I just keep coming back to different Project Farm videos lately! thank you for all the hard work!

Try two old tricks I was shown 35 years ago by a old timer(60+). 1)Shock(hammer) the plate or parts next to the bolt. Use brass/lead hammer or pad it with a peace of soft wood. 2 or 3 good firm stikes. Works great, no chemicals spills to remove. 2) Tighten the bolt slightly. 1/8 turn or so. It breaks the rust and does not start the removal of the bolt with pushing the rust into the threads. I use these so often a young guy at work thinks I can't hammer and forget the direction to turn the bolts. I love removing bolt he gave up on, right in front of him. I have shown him and explained the theory behind them.

I was surprised at the results. Last week I spent 7 hours on a stuck bell housing bolt. I used every tool I have including torch and impact. I was at a loss so I sprayed PB Blaster (recommended by a friend) and went to bed. In the morning the bolt was finger loose! Crazy. I’m now a firm believer in PB Blaster but I’m going to try Liquid Wrench now too. Great video sir!

You are totally awesome . I can’t find something better to say other than “may God reward you and guide your heart”

Dear PF, I have a couple of things to say. First, you are doing well with your videos and performance progression. Your voice has more energy in it in newer videos. Good on you, sir. Second, I saw that you had replied to a comment from a few months ago. I've never heard of a KZfaqr doing that, let alone seen it. Thank you for your dedication. PSA over. Keep up the good work!

Being a master automotive technician I also have utilized all the products you did minus the acetone and transmission fluid mixture. From day to day 35 year hands-on experience I came up with the same conclusion that you did. It was an interesting show down to say the least. Thank you.

My dad would always get the Liquid wrench from the auto parts store and tell me "aaaahhh its good enough" turns out it was very good and better off.

As a hobby I restore old motorcycles, I believe in PB-BLASTER. From frozen bolts to stuck pistons in rusted cylinders. You just can't beat the penetration of this oil...

Excellent video....as always. Thank you. I used to use WD 40, then Liquid Wrench, then ordinary gun oil/cleaner. Honestly, none of these things seemed to work for me. Finally, while I was in a small engine repair shop one of the mechanics told me about PB Blaster....he said it was the best he had found. So, I immediately went and bought some PB Blaster, took it home, and applied it to the stuck bolt in the aluminum trans case of by pos John Deere riding mower. After an hour I tried to loosen the stuck bolt....nothing. I sprayed again, waited another hour....nothing. Finally, I gave up, sprayed the stuck bolt again, and let it sit over night. So, the next day, just before I was going to light the fuse to the stick of dynamite I had waiting for the JD, I decided to try to loosen the stuck bolt one final time. Amazingly, as soon as I put the socket to the bolt, it simply turned....and was loose. The clouds parted, a bright beam of sunlight shone down, and the nearly departed pos John Deere mower had "new life"....and a new name...."Lazarus". So, I have been using PB Blaster all these years since then and, of the products I have tried, I highly recommend the PB Blaster over any others I have used

I absolutely love how you seem to think of EVERYTHING when doing these tests, such as putting the nuts on the studs with the beveled edge down and covering the bolts not being treated as each new set was being treated. GREAT WORK!

Thanks for including results in the video description! I've watched many of your videos to know I can trust your results, this time I was in a hurry and appreciate it!!!

You deserve every single like and subscribe you get. Definitely in the top 5 of my favourite channels on KZfaq.

2 year old video and still replying to comments. That’s dedication to your subscribers. You’re doing an amazing job and definitely deserve more recognition. I’m still working my way down your video list as I recently found your page about a week ago. Wish I would’ve discovered your page sooner! Keep up the fantastic work!

projext farm i aint even in to this sort of stuff but im addicted i love how you talk to your viewers you explain to a point where you don't dumb it down or over complicate it your a legend :D

This guy is great!!! I love listening to his stuff, especially on the stuff I havened bought yet!!!

Thank you for all your testing and excellent reviews. I immensely enjoy your videos and recommendations. Being a retired merchant marine engineer, we have had plenty of exposure with rusty fasteners on sea going ships. One of the major enemies to seafaring ships are salt water and sea spray. At one time or another we have used all the penetrants you have tested in your video (except the home brew). The top two we found to be most successful was the Kroil and the PB Blaster. The Kroil we would get in one gallon cans the PB Blaster in 5 gallon cans. The most unique thing we found with Kroil and PB Blaster was its effectiveness was almost immediately where as for the others they required a soak time.

This was really interesting for me. I grew up on a dairy farm and we always had Liquid Wrench around. I was pleasantly surprised to see that it did so well. Great channel. Thank you

Great test. If you do this again, I would love to see if any of these actually penetrate the threads. After breaking the torque off, you could remove the nut and see if the oils went down into the threads.

Thanks for the testing and the work you put into these videos. Great intel for the DIY'er and professionals alike.

My man you’re awesome the charts and everything. Exactly what I was looking for.

*glances at my can of WD-40 judgingly

I am always impressed by your thoroughness, and your attention to details in the testing processes. You may not be a scientist, but you sure think like one.

Thank you for your diligence in the testing you do on any of your comparisons, I watch them all. In the 40 something years that I've been working on rusted things I can say I've never been overly impressed with any of these products except maybe Castle Thrust but in the end you can't beat the fire wrench.

That was a simple, thorough and easy-to-follow video. Awesome! And very helpful. Thanks for sharing the knowledge.

Blue tipped wrench always wins! Sometimes confined spaces should prevent using. I’ve been having good luck with Sea Foam’s Deep Creep.

That was a great test, I have never seen a big difference in all of the products I have tried in the past 50 years. Thanks

You definitely deserve to be prideful of your videos Bud. Not only is everything that you're saying very interesting, but your videos are also very informative to consumers that are laymen when it comes to the knowledge that you present. Keep up the good work. I'm glad I found your videos.

This is your best video that I have viewed, you seem so much calmer and personable. I would guess it’s mostly editing as you have to cut down the video so it’s not to long. Regardless very good, enough that I noticed and commented. Thank you for your work, much appreciated. BTW my wife likes the videos too, so informative.

Best product review video on the internet. Well done, sir.

I've always been a fan of Liquid Wrench (or fire wrench when you can), and was happy to see it do well. One thing you could add is that tapping on the nut or bolt after you've applied the penetrating oil makes a helpful difference most of the time. Thanks for the video. *:D*

I've used liquid wrench since I was a child in the early 1950's. My dad was an auto mechanic, and I still remember an old can of liquid wrench in a cabinet in the garage. I guess the smell of that product is what takes me back to my childhood! It's not a bad smell, but it is distinctively liquid wrench. I stopped into Tractor supply today to get some liquid wrench. They had three kinds of liquid wrench, but they were out of the "ORIGINAL liquid wrench. I guess everyone in Dripping Springs Texas watched this KZfaq video!!

I FOUND IT! This is the first video I ever watched by you, but it's not the one I subscribed on. Now we're looking for that.

Thank you for the video. Did not realize it was an oldie, but certainly a goodie. Appreciate it, I am going to pick up some liquid wrench. You solved my which one do I choose dilemma. all the best, Dono

Hey that was excellent and fair. I've learned that you really try hard and succeed to be equal to all the products. I appreciate and trust your efforts. Great Job and I'm going to use your recommendations!!

Thanks for another great objective product testing. As an engineer, I can appreciate your scientific and non-biased methodology. Keep these videos coming.

Wow! Useful info we can use. Keep up the great content. Thanks 🙏.

Thanks again. I always know where to look when I’m looking for the best product!

I am grateful to have stumbled on your videos. I subscribed which is unheard of for me. Your testing is thorough and I love that you aren’t sponsored. I have a hobby farm and you test the products I use everyday. Thank you!

You broke my heart man. I've been using pb blaster for years haha another great video. At least pb blaster is great at killing wasps

Been using the homemade stuff for years, Good stuff. Lov your channel Gramps

This is probably the best product review channel on the internet. I refer many people that are looking to buy products to your channel - let the data speak for itself. WRT the penetrating fluids, I have used Liquid Wrench, Kroil, Sea Foam and PB Blaster - none of them work. Heat, when I can use it, is my best friend. Because of a dry rotted tire, I recently had to remove a wheel on one of my trailers and the nuts were rusted. The wheels hadn't been removed in 30 years. I tried all of my leftover cans of penetrating fluids and none of them worked. I applied them to the lug nuts every day for one week and still had to use a breaker bar. Upon inspection, I observed that the fluid did not penetrate past the first thread or two. I have several cans of chemicals if someone wants to stop by and pick them up!

If I was a billionaire, you'd have your multi-million dollar lab for sure. Thanks for the video.

Man you are the most Honest farmer I have ever known!

Brilliant video very entertaining and very informative you have saved me quite a bit of over the past, carry on doing all these tests cheers 👍🏼👍🏼👍🏼👍🏼👍🏼

Mahalo from Hawaii. Appreciate your focus to do these test’s right

I just found your videos. This is really helpful to me cause I’m going to let you buy all the products then I’m going to buy the one that worked the best. Thanks and have a great day.

This guy is better than Consumer Report! He owes no one and gives the best unbiased findings! Glad I subscribed! You should too!

Great video as always. Heat has always been my go to but I've got a rusted on plastic thermostat housing and heat would destroy the part so I need an alternative due to the context of this specific application. Never would have guessed liquid wrench is the winner. Thanks for your great work!

Great job as always, thank you so much for all you do!

Great video! I’m looking to tackle a frozen stud and was hoping you’d explored this category. Your efforts are a blessing to us DIY-ers!

As time continues on I find more of the specific questions I have answered on your channel xD I know some videos cost more than others but the time and money you have saved me from your tests over the years has helped so much. And your reviews are always balanced and fair I feel, from best option to best bargain comparisons, thank you for the vids! :D

Great video!!!! Thanks for all your hardwork

You have the best channel on KZfaq! Well done!

Great Job! Love your videos. I’m a yacht engineer and I can honestly say that people in the industry have seen your videos and heard of you. You’re making a useful impact and I appreciate it. Keep them coming!

Every test this gentleman has ever done is very informative. Thank you sir!

I was thinking use a torch. Then You did. That made this video 100x better.

Thank you for comparing these products with such great detail.

For 20 years, I've listened to fellow Jeepers argue whether PB Blaster was better than Liquid Wrench. I always leaned towards PB, but this changes my mind. Thanks for all of your videos, you do a great job with them!

Great channel! I really appreciate the way you lay out your tests and your great attitude in general. You always see the way to get consistency and validity with your test parameters. I've been recommending Liquid Wrench for about 30 years now. Nothing works better on the tough fasteners. Nice to have you demonstrate it. The old formula was stronger, but nasty smell!

I have a motor mount bolt stuck in the metal sleeve through the bushing. I was using PB Blaster to try to cut through the rust, then saw Liquid Wrench tested better, and I happen to have a can of that as well. These videos are still useful years later!

Great test, I was a little surprised of some of the results. Thanks for sharing.

Thank you sir! I’m very appreciative of your reviews.

I’m a little shocked on the results. I’ve always been happy with PB blaster but looks like I’m going to give liquid wrench a try. Awesome videos!

I am a kroil fan because I use it on 650 degree valves on the spindle threads and collar. Once worked in, it allows the best turning of a 36" valve than any other safe lube. It doesn't evaporate as quick; yet, is light enough to penetrate and lube it. Try turning a valve 990 turns to open it, then you will see...

I have used the second place for a long time. We put it in a 4 cylinder engine that was frozen. 3 days of letting it soak the engine turned over. I enjoyed your show. Thank You

Keep up the great work man!

I love PB Blaster because you can shoot it across the driveway and lube that nut under your truck before you crawl under there to wrestle with it. Also helpful when defending yourself against the wasp nest you discover once you get underneath there.

PB Blaster. Used it for the first time while trying to break axles free from a rusted wheel bearing assembly. Used several cans of Liquid Wrench without results. Bought a single can of PB Blaster and it worked. I was able to remove the axles without too much trouble.

This guy does the best in depth test I've ever seen

Thank you again for a great video and your time. How long did you leave the bolts out to get that much corrosion anyway? I've always just used what i had..WD40 but I've also used Liquid wrench because thats what what my dad used..glad to see he was right. I will probably never make my own home brew like you so I'll just stick with the Liquid Wrench..or heat Please..cordless long handled hedge trimmer

When I first started as a mechanic an old greybeard told me to use brake fluid. The best by far. Please like so it can be put to a true test!

I'm a Kroil guy, and I think I just bought my last can. Thanks for the great video.

I’ve been using liquid wrench since watching these videos and it works well. I am just sick of the smell so I might test out some of the other options

The best advice I have for using any penetrating oil, is to use it liberally over the course of several days. If you don’t have several days, heat is your best friend.

It’s quite interesting over the years of having a large shop and using different products, that sometimes the sales of the different penetrating oils and their slogans seem draw us to gravitate towards one over the other, especially the one with the capillary action! There’s always the proof is in the pudding over sales gimmicks! Great review I enjoyed it : )

Thanks for taking the time. I appreciate the information. Thumbs Up!!!

I've never had alot of luck with penetrating oils for stuck and rusted fasteners, I prefer kroil though for lubricating everything else, especially any kind of hinge, pivot point or mechanism. Seems to last the longest and do a better job loosening sticky joints. And I've tried all the ones you tested out here, but liquid wrench I always thought was a pretty good alternative which you proved here.
