How To: Use Muriatic Acid to Clean Metal Before Welding - Crappy Trailer Restoration Pt. 2

[@davedovala2700]

I can see it in Danny's eyes, you being so bright and inquisitive makes teaching fun! There's no better feeling than knowing your little bits of insight will carry on.

[@emehlhar]

Good info on using that acid. A bit extra info about it people might want to know. The fumes from use and even idle evaporation are bad. They will rust any metal in the vicinity. Even as much as ten feet around the bottle. Best keep the container outside or double bagged if stored inside.

[@willysnowman]

They will rust even if the bottle is closed.

[@ke6bnl]

@@willysnowman I did some small parts for solder out doors and brought in to solder only to fine that he newly built offroad buggy frame was completely rusty along with everything in the shop. be carefull

[@sheldondyck8631]

If I were you, I’d get new trailer fenders, cut off the old ones, then weld tabs to the trailer frame and bolt the fenders to the tabs. That way they’re removable should one get damaged or whatever. Just my opinion though. Do whatever you think is right I’m sure it’ll turn out great. Cheers 🍻

[@sharkskinboy]

I used muriatic acid many years ago as an experiment to clean the rust off my old headers before painting. It worked beautifully. I used no gloves and no breathing protection though (I was young). It didn't smell great, but the only side effect was my right eye was twitching for a couple of days afterwards LOL.

[@clintwilliams5026]

Remember kids, ADD ACID (A.A.) when diluting acid do not add water to acid. Always add acid to water.

[@jacklisiecki2389]

Thanks Faye. Wow! The previous welder must have been blindfolded. I always hated working with muriatic acid - dissolves blue jeans, coveralls, and everything else really well! Thanks for another video.

[@darkfactory8082]

Ya, that trailer is actually not welded at all, it's just "weld spitted".. Who built that shoud have taken at least some time in practice before, if he wasn't practical.. The wiring job also was a disaster, should have some nice holes with grommets where it goes through metal components. It looks like they just thrown together some junk laying around... Before reusing wires, check them for peel or damage, otherwise you will always have some unexplained troubles.. =) Keep on, looking forward to see it coming redone. Muriatic acid is a bad ass thing, I've used it to clean all the profiles for my carport/crane/service bay... It worked wonderfully. Cheers, mama Faye!

[@FayeHadley]

Thank you!!! Yeah, it made me feel better about myself seeing those welds for SURE HAHA! I'm excited to see where I can take this thing!!

[@TheEvilways101]

I just weld that galvanized.. dont care. I do it outside, or with alot if ventilation fans on & hold my breath while welding & walk away for a bit & then go back… that acid i feel is waaay more dangerous

That was definitely welded with a sparklermatic 220

[@FayeHadley]

🤣🤣🤣🤣🤣

[@Banjoandguns]

I’d just use a wire wheel and acetone to clean it. Put rags away or outside when welding. Muriatic acid can do permanent lung damage it’s no joke. Evapor rust stuff is non toxic

[@BlackEpyon]

I've got muriatic acid on hand that I was using for something else. I should try i next time I need to weld galvanized. I always grind off the coating first, and weld outside. BTW, I'd recommend spray-on rocker-guard on the inside of the fenders. That'll save you from having the paint flake off from gravel spray, and rotting the fenders out from the inside.

[@billdrake9849]

Over the years I have bought and sold a lot of used trailers. So I was impressed that you bought a trailer for $100 and it even had fenders on it. You managed to tow it home without having the tires come apart or the wheelbearings freezing up. OK so was that $100 the asking price or did you negotiate that down. Also what was the cost to have the trailer sandblasted. Never had anything sandblasted before always thought about it. Thanks for the informative video

[@KrazyGoodMods]

Lots of good advise from Danny! I used muriatic acid on my truck's recovery shackle to strip the galvanize before powder coating. Besides smoking, the shackle became warm to the touch!

[@FayeHadley]

YES!!! I experienced that too! So crazy!

[@Blazer02LS]

@@FayeHadley Exothermic reaction. You can cause the same thing just by mixing the acid and water in the wrong way. "Add acid to water like you ought to"

[@RangePisteMies]

By the gods, who ever weld that trailer in the first place have no welding/fabrication skills at all🤣 Good job Faye! Thanks for Danny all help! Cheers!🍺🇫🇮

[@BlackEpyon]

You'd think they'd have tried some test beads first. The tube welds don't look half bad, but the fenders are atrocious! Likely used a cheap welder that didn't have a lower current setting. Sheet metal is easy to burn through.

[@buddyrevell6369]

If you use phosphoric acid instead, you don't have to worry about neutralizing before painting. Never heard of anyone using muriatic acid for paint prep. Always phosphoric.

[@FayeHadley]

I used phosphoric acid in another video, and also just a few days ago to keep the trailer from rusting before I paint it! It doesn't remove galvanized coating though, so it wouldn't have worked for this application!!

[@rafaelmuniz9812]

Hi my dear i loved your vídeo and you are very beautiful kisses

[@clayfist4033]

Excellent video Faye I would’ve got some little pieces of channel cut them fenders off and then bend some metal and then screw them on so it’ll be a lot stronger case you have to remove it and then the other metal I would cut out and put stronger bars across it thought of trying to re-weld the existing metal that somebody didn’t know how to weld at the time good video keep up the good work can’t wait to see you next one you’re awesome thank you

[@moparone7962]

I never wear gloves or a respirator when I use muriatic.....hey your tattoos look cool. My mom likes me, don't matter what you say...

[@FayeHadley]

BAAAHAHAHAHAHA AMAZING

[@Jpilgrim30]

Muriatic acid works great to remove bearing material from a crankshaft that had a seized rod bearing. It’s awesome stuff when used properly.

[@randombytes3998]

aren't you neutralizing some of the muriatic acid by collecting the baking soda rinse water?

[@Urs4]

When you do the welding like here, actual welding is 10% of the job, makin parts to fit and cleaning them for welding is 90%. As you have good welding machine you can cheat on preparation (as i also tend to do). But if you prepare your welding and figure out how to make them then you can do all your welding by yourself on your future projects, and be proud of yourself, if you like to weld.

[@SUMOCAT86]

It boggles my mind, why would someone keep going around the whole trailer when they can clearly see it's not working and they can't weld at all.

[@FayeHadley]

I have no idea!! Necessity??

[@armandocastillo8287]

I like what you do Faye very happy person in your wick thank you for shareing the things you do thank you

[@joubess]

Excellent safety lesson on muriatic acid, known in the chemical industry as hydrochloric acid, HCl. It is dangerous and very corrosive to metals, but at 20% solution with water can be used to clean old tile and grout and at 10% can clean dirty or stained concrete. When diluting acid, always add the water to the container first and add the acid to the water. If you add water to strong concentrated acid it generates a lot more heat and will melt the container, break it, and the solution will boil violently splashing acid all over the place, including all over you. Please encourage Danny to wear safety glasses when using his barrel of muriatic acid! You never know when a drop of any chemical is going to go flying and hit your eye. I speak as someone who has gotten a single drop of a corrosive chemical in an eye, and I was wearing my safety glasses at the time. It plopped over the top of my left lens somehow. My eye is fine. I immediately washed it out of 20 min with water then reported to medical and they drove me to an ophthalmologist. He examined my eye for damage and found a small amount of damage that would heal in a week by itself. I had to use eye drops and wear an eye patch, but it healed nicely and has not effected my vision in the long run. But, it hurt like hell and they gave me some pretty strong pain pills to use for a few days until it healed.

[@cdrom1070]

meanwhile treatment for grinder dust, when you are old, will cost you 10k a month. You made the smarter move using chemicals then going at it like a psycho baboon with a spinning rock. the HCl is easier to manage, and less harmful in the long run. You need to design your tools not to splash and stuff though (this means paying extra for beefy containers that have pouring features ETC).

[@NFSgadzooks]

FYI, some of that bubbling is flammable hydrogen gas being released from the acid reacting with the zinc. Just something to keep in mind

[@maka5955]

The requirements for self-made trailers here are tricky. That it is easier to buy about € 200 scrap where there is only the body number plate and papers left. And make a new trialer using them.

[@FayeHadley]

Oh, interesting loophole!!

[@jayinmi3706]

I almost feel like some trailer fenders from like Tractor Supply would be an easier way to go. lol But still interesting. I bought a house and there were 3 big glass jugs of this stuff in the basement. My friend wouldn't go down there, she got a bad vibe like it was haunted. We wondered if someone used it to dispose of someone. haha

[@FayeHadley]

COULD BE!!!

[@ProleDaddy]

*note to self

[@brandonGCHACHU]

I worked in a commercial AC manufacturing plant as a welder building the large galvanized AC bases. We welded galvanized steel all day outside with no respirator and no it doesn't kill you immediately like everyone on KZbin says but it certainly isn't good for you in the long haul. If you have to weld it just do it outside and wear a mask and you're fine.

[@ProleDaddy]

Sound's like your employer doesn't give a shit about their workers. I'm shocked... No I'm not.

[@cobramike13bravo63]

I usally add muradic acid to my batches of meth, it really gives it that punch to the teeth.

[@FayeHadley]

Eewww BAAAHAHA

[@boris9331]

Nice video. I use quite a few acids and caustics for cleaning. Some that work great for rust, don't work good for oil/sludge and vice versa. Simple Green aviation over night is great for loosening sludge and is very safe and non hazourdous, it's expensive but safe on precious parts like Alluminium, some parts need a couple of days in the tank with some agitation here and there to speed it up. You can use a Hot caustic cleaner e.g from Atotech (Uniclean x40), or Macdermid Enprep 114, but they require heating to high temperatures which is expensive and lots of fumes, and only for metal (no alluminium), - saves on time though. Benco B17 (Methylene Chloride / Formic Acid / Phenol mix) is great for oil/paint, but extremely hazardous and risky stuff, treat it as liquid fire or you are in big trouble, it evaporates quick if not contained. Works great. Then yes Hydrochloric (Muriatic acid) great for removing rust, just don't let it sit there for too long. Often some of the rust that hasn't come off is very loose and comes off with a very light scrubbing with a scotchbrite sponge, easy. Just use a water rinse after the acid to avoid flash rusting and dry it immediately. Blasting if done thorough will remove most/all galvanizing (zinc), but often certain areas might not be done thoroughly so some Hydrochloric acid can help remove residual bits of zinc as a safe measure. As others mentioned, not good to be using Acids or Caustics in a enclosed environment on the regular, fumes will float and land on metals, e.g nearby parts, or eventually if you use it all the time, rust the roller doors and metal roofing, it happens so slowly you won't notice it until it takes effect. I did recall Faye you said you could use Muriatic acid to clean bolts. Yes you can, but as Hydrochloric (Muriatic) acid reacts with Zinc and Chromium (when you see it fizzing), its stripping the Chromium (yellow or silver finish on bolts), then the underlying zinc off, The bolts will readily rust afterwards unless you get them zinc plated again which is costly. Best is to clean bolts just with degreaser or immerse in gasoline or whatever works to get oil off.

[@jozsefizsak]

Now playing - Crappy Trailer 2: Be Afraid. Be Very Afraid. Well anyway, I'm so relieved that you know not to weld that stuff because of its toxicity.

[@lonniehand1386]

if you put the baking soda water in the muriatic acid it will be neutralized so u can't reuse it

[@FayeHadley]

Exactly! That's how you dispose of it safely! I saved the stuff that didn't have baking soda contamination!

[@deankay4434]

I think Stevie Wonder was trying a welding class on that trailer that day. We had a "Crank-Top" Lincoln stick welder on the farm and my step dad & his dad, neither knew how to weld so by age 10 (The Oldest) I was the resident welder on broken equipment! Yes, crank-top? Anyone ever seen one? It had a 10" crank on top with a knob, a vertical pointer for amperage, and would simply lift the primary side of the transformer up or down, controlling amps by mutual induction. The more of it lowered into the secondary part of the transformer, the more amps you got. I have seen a guy re-wire one and turn it into a battery charger. Just added more press-in diodes used in the Delco 10S alternator to create a more controlled (-) negative and (+) positive. You could buy them at farm auctions for under $10 to $5 dollars. Most had a broken wire inside from moving. The old tar-soaked insulation over copper! Serious! DK, Omaha.

[@denverdanoreno]

Very informative tutorial on using muriatic acid. Hydrofluoric acid works very well but it's extremely expensive and using a Alkali soap such as lye soap. What I'm not familiar with and I guess I could do a little bit of research is should I still use baking soda to neutralize everything? But the lye soap, should do it? Stay young

[@marcussho]

Love using Muriatic acid for mill scale removal, also a weed sprayer comes in handy for neutralizing the acid!

The oil pan is cadmium-coated, not galvanized. But the principle is still the same. You might mention, (when diluting) you always add acid to water, not water to acid... just sayin.

[@VorpalForceField]

When diluting acids .. ALWAYS add acid to water .... do NOT add water to acid ... when working with strong acids monitor the temperature during dilution especially in warm weather ... solutions can get very hot.. exothermic runaway can can get hot enough to melt low temp plastics as well as generating massive off gassing.

[@abruptlyblunt]

there's no way you removed all the galvanizing from vertical surfaces by brushing on the hydrochloric acid, it runs off to fast. I guarantee that if you were to submerge that same metal you already brushed in hydrochloric acid you'd still see a lot of chemical reaction from the remaining galvanization. i'm not saying it's a bad thing, you just need to be aware of it and take two extra steps over and above being in a well ventilated area when welding galvanized metal, you need a fan blowing directly across the piece you are welding so the fumes can't rise up toward you and you need to take milk breaks every hour or so. i honestly don't know the technical reason for the milk but every old timer welder i've ever known has said when welding galvanized drink lots of milk to help protect you from the effects it can have... just sharing with a fellow or fellowette DIY'er...ps: you should have charged them a $100 to haul away that so-called trailer.....

[@mrdavidurquhart]

So how do you deal with the flash rust? Maybe you do your welding and the do another quick acid dip and neutralize dip. Then send it off to be galvanised again... I had something sandblasted once and the shop asked me if I wanted it undercoated so that's a way forward post-weld. Sorry I'm kind of obsessive. And does

[@auhsojyihst9440]

Great content. Love it. But was nervous with young lady having her arms and legs almost entirely not covered while being close to the deadly acid. A slide jump of a drop can catch your body and cause serious burn.

[@earlmcgill5867]

Another reason for not using it indoors, the vapors will attack anything metal. This will include all of your tools, wiring, and plumbing. Lessons learned the hard way.

[@mbsnyderc]

I'm not sure this trailer is worth the work those are the worst welds I've ever seen,and is made out of galvanized pipe strong vertically not so much horizontally.I wouldn't haul anything real heavy on it.

[@tabbott429]

I just used 25% viniegar/water mix to de rust parts. Its much safer and easier although you need 3 to 7 days to soak the parts so there is no scrubbing required. I restored a 58 Bel Air and every part that fit in a 50 gallon plastic drum got soaked in vinegar water mix for a week or so before i repainted them. No sandblasting needed.

[@bsrcat1]

If you're going to save your acid, make sure you remove the pan and let the baking soda drip on the floor. Whatever drips on the floor will be neutralized at that point so it won't harm anything. If you let it fall in the acid it will lower the pH and defeat the purpose of saving it.

[@seancaceres619]

Acid dip the block, neutralize it and then leave it in a drum of oil until ready to work on. If you sandblasted or mediablasted the trailer instead of using acid it wouldn't flash rust because some media is treated with (Zinc?) And leaves a film on the metal

I would not bother trying to fix someone else’s mess. If new fenders are not an option in the budget then I would cut approx 1 inch off the existing fenders getting rid of the mess then weld on an all new metal hem or flange onto the fenders. A better outcome with far less work Muriatic acid is very aggressive and very toxic on its own but the gases are also very toxic and harmful, this video was a little light on stressing the dangers and that a person should always use personal protection including glasses or shield even when using outside.

That acid has 101 uses. Cleaning all kinds of things. Metal you want to weld or solder. (we used it in a rad shop all the time), your toilet, and yes, it can be used on concrete. It is commonly used (diluted) on concrete to "etch it" before painting. Also good for cleaning electrical contacts and fixing sending units from that crappy old gas tank. In all cases, it must be rinsed and neutralized when you are done.
