  • In previous videos we tested seafoam deep creep and then in a separate video
  • We tested liquid wrench and both of those win in their respective showdowns is it possible though that there's a product that's even better for
  • removing rusty bolts and nuts than sea foam or liquid wrench
  • in some of the videos i've seen online which I find very hard to believe some people are using nothing other than candle wax to remove
  • Rusted parts and if you have a wheel stud lug or a lug nut on a vehicle that's been in place for twenty years
  • It's gonna be very hard to remove it if it's been exposed to weather and it's full of rust
  • So is it possible that all you need is just a cigarette lighter and a candle in order to remove that rusty
  • lug nut
  • well I'm not sure if that's a myth or not
  • But what I do know is by the end of this video we'll all have some conclusive evidence as to whether or not this works
  • The first test involves determining whether or not using candle wax works better than using nothing at all
  • On the right we have four bolts this is an old sickle mower
  • Part that I used as scrap it's just scrap steel for me
  • but I would add torque each one of these bolts down to 50 foot-pounds this is a
  • 7/16 bolt and I allowed this to rust for a period of time and I also used a rusting agent to create some rust
  • So we'll see how much force it takes to break these free
  • Normally breakaway torque is less than the initial torque so we should expect these to come loose at 50 foot-pounds
  • or less
  • if they weren't rusted at all
  • So let's see how much force it takes now you don't need a torch to do this according to the videos I've seen
  • you just take a regular lighter you apply a flame to the very bottom of the nut and
  • Then you allow it to heat up the nut to the point in which the wax melts
  • Now as the wax melts in theory what's supposed to happen
  • Is the wax creeps in between or whicker's in between the nut and the bolt
  • Allowing it to fully penetrate and then of course loosen everything up
  • so let's put this to the test we're going to use four different nuts to put apply the
  • Wax to and they were going to test it against a control which involves no wax
  • We're also going to allow these to all cool down
  • As you can see the wax has totally coated the entire nut-and-bolt so it should have had a chance to wicker in
  • Since we applied heat and wax to the other group of bolts we're only going to apply heat to this set of bolts just to
  • make it fair because heat in and of itself could break away some of the rust
  • So we'll apply heat for 30 seconds just like we did the other bolts and then we'll allow to cool
  • As you can see the surface area of the nut and bolt is thoroughly coated with wax and wax has actually gone down the side
  • The metal and it's begun to drip off
  • At this point everything is cooled off so what I'm to do now is measure the torque required to loosen each of these nuts we're
  • Going to be using a torque adapter to measure the amount of force required to break free each one of these
  • nuts
  • But what I do like about this specific model is it does measure the loosening torque not just the tightening torque and it also records
  • the highest amount of torque required to break something free
  • So what do now is remove this
  • Nut
  • let's see if we can find any sort of wax on the inside of the nut and bolt I
  • Don't see any sign of wax in this bolt so we're gonna remove the next one and see if maybe there's some wax on that
  • one
  • Just like the first bolt there's no visible presence of wax
  • Just like the first two bolts unfortunately there's no visible sign of wax getting into the threads of this bolt
  • gonna remove the nuts and these bolts and we'll compare them to the bolts that had wax apply to see if they look any different
  • so
  • The bolt on the right had the wax applied the bolt ton left didn't I can't tell any difference between the two bolts
  • I'm just not seeing that the wax made any sort of progress getting into these threads
  • Now the previous set of nuts and bolts and this set had, been rusted the exact same amount and torque to 50 foot-pounds
  • also the bolts and nuts are the exact same size I
  • Intentionally did not cause a whole lot of rust to occur with either one of these test setups because I wanted to see if wax
  • Would do anything on a mildly rusty nut and bolt
  • so
  • what we're going to do now is apply an incredible amount of heat to these nuts and bolts
  • Then drip wax directly on top of the bolt itself
  • To see if wax will work its way into the threads
  • We're gonna do that for just two nuts and bolts the other two is more of our control we're just going to apply heat and
  • Nothing as far as the wax and we'll compare how much breakaway force is required to loosen these up
  • I'll just be using a propane torch to heat these nuts and bolts up
  • We're going to apply the wax to see if this is gonna work
  • We'll go ahead and allow these bolts to cool off to room temperature and then we'll see how much torque it takes to remove them
  • We're gonna start off by seeing how much torque it takes to loosen the two bolts that only had heat applied and then we're gonna test
  • The two that had the candle wax okay the metal is totally cooled off now the entire piece of steel is
  • 79 degrees 78 79 degrees Fahrenheit
  • There are no visible traces of wax on this bolt unfortunately it does not look like this is working
  • So I'm very curious as to whether or not a penetrating fluid would do a better job than candle wax or having nothing
  • So, what i'm gonna do now is apply a lot of heat just like we did before using a propane torch and then
  • I must spray this down with seafoam deep creep
  • This is the badly rusted wheel stud lug that we heated up to about 700 degrees Fahrenheit and then
  • Used, candle wax on top of it so what
  • I'm going to do is see how much torque it takes to break it loose now
  • I'm not going to take it off once I break it loose I'm going to actually cut this nut off
  • So we can actually see if there's candle wax that's made it into the threads
  • There's no visible signs of wax on these threads it did not do a good job as far as penetrating
  • The seafoam made thorough
  • Penetration it is still on the threads even though the reciprocating saw did cause a lot of heat and we saw some of that evaporating off
  • Now it did what it's supposed to do it actually
  • penetrated and helped release the nut
  • The candle wax on the other hand it took about two and a half almost three times as much force to break the nut free
  • and there's no visible signs of candle wax on these threads well I don't know about you but if I've got a deal with the
  • rusty nut and bolt in the future I'm not going to be using candle wax it did absolutely
  • nothing for me besides make a mess now I watched quite a few videos on YouTube to figure out the different strategies to apply the
  • Wax and I tried a couple of those on this video and neither one of them seemed to work at all
  • What did work, was applying the penetrating fluid to the rusty nut and bolt
  • I don't recommend using heat
  • when you use the penetrating fluid just because it can reach Auto ignition and catch on fire and
  • Obviously you've got to be safe you don't want to do that as I like to say work smarter not harder and definitely be safe
  • Now regarding the approach I used different people have different opinions on this approach if you think I did a poor job
  • I'd like to hear your comments and what I should have done differently
  • I always learn from you guys there's a lot of different opinions and I read every comment
  • so
  • I look forward to reading your comments and I look forward to future video ideas
  • until next time please take care and I look forward to seeing you then

Description

The Project Farm Channel strives to achieve excellence in testing products and different strategies to work smarter, not harder. No hidden agendas, nothing to sell and no sponsors to please. So, is the use of a lighter and candle wax an effective strategy to remove rusty nuts and bolts? You've probably seen videos on YouTube using this approach, but where's the proof that it actually works? In this video, I use 3 different tests to measure the effectiveness of using candle wax and a lighter/propane torch. In one test, I compare a penetrating fluid against candle wax. I am not sponsored by Seafoam, Liquid Wrench, the maker of the candles, the lighter or propane torch I used. I buy all products shown in the video and am not sponsored at all. Hope you enjoy the video! Thank you very much for supporting the channel by watching the commercials and through Patreon support. https://www.patreon.com/projectfarm
