Muriatic acid called hydrochloric acid will attack the base metal if left long enough. It is recommended to wear solid rubber gloves and eye protection. Diluting the acid may involve using gas resperator as it fumes chlorine gas .I'm an Industrial chemist.

So fantastic and humbling to see people still taking trades work so seriously and learning and proving their skills. We need more of this in the world .

I had a jug of muriatic acid that I had just opened to do a project with inside of my garage. It was a beautiful 1930 Model A two door sedan with great paint and really no body work necessary. I got called away for an emergency that took me out of town for a couple of days. I had pushed the jug beneath a bench to keep it away from any child or such knocking it over, but I totally forgot to check the cap to the jug. When I returned home a few days later, the smell inside the garage was awful and virtually anything not painted on that car was rusted completely. Things on the dash, the underbelly and anywhere at all you could imagine. Boy, did I ever cry when that happened. It was one expensive mistake, so if you use muriatic acid, be sure to seal it tightly as it will get into the atmosphere as you said, and you will not believe the damage it can do to everything on the car, but inside the garage where anything of metal will be attacked, as well. Our water heater was out in the garage, and it too took a hit on metal parts due to my ignorance at that time. Be overly cautious in using it is just not enough of a warning once you flub up as I did with the stuff. ;-(

Glad you mentioned the baking soda. It makes a.big difference followed by quick drying. Good video thank you

Im fixing a 1974 CB750 Honda tank. I had a good shell but bottom was rotted. Got a second tank with a good bottom. Split both, welded good halves together. BUT, im in Florida and the humidity rusted the outside of the shell. I use muriatic to get rust out of the inside , now i know i can save the outside as well. Thank you. Oh, im from Nashua, NH, so i love the accent.

I think you've triggered a flashback... I agreed to paint a friends '67 E-Type. He was so very proud of having already stripped it with paint remover (destroying all of the rubber in the process) and putting it under a cover, outside, a couple of years prior. Many gallons of muriatic later, with lots of elbow grease, we had a finish that took best in show in Phoenix.

Thanks for the tips , I've used Ospho for years but you changed the way I will do things , thanks so much I restore old VWs and loved the piece about that young man's little vw project, I would sure love to have that

Muriatic Acid comes in different strengths. I like the 31.45% HASA from the local Pool Supplier. Must to do out doors and stay up-wind. A simple cheap paint brush is all you need. No need for abrasives or rubbing at all. Just brush it on, keep it wet and in 5 mins the rust will disappear before your eyes. Brand new metal to be had. Speaking of eyes, goggles a must! Couldn't imagine getting that in the eye. You MUST neutralize the acid. Prep a sprayer with Baking Soda and water and spray the acid. Muriatic acid reacts with baking soda to form table salt (NaCl), carbon dioxide gas (CO2), and water (H2O). It appears as a foam. After neutralizing hose it all off and dry quickly to prevent flash rusting, It's fast and easy. I just did an entire front-clip. Great results.

Happy to have found you. Just looking to remove bits of rust from a metal railing around my porch so I can paint it. Now I know more about products and application. I'm fascinated with your work. Thank you.

You are absolutely correct about media blasters and the damage they can do. You are spot on with the "cover the area with plastic for extending the acting properties of the chemicals for stripping, as you are with safety (running water, gloves, etc.). Perhaps you are my lost younger brother...we think alike in many ways, although I am retired. It is fun and rewarding to watch your videos and your sincere intent on passing artist-craftsman values to others.

Just a pro tip... I use those pad you put on the floor for aminal mistakes, they are cotton backed with plastic... you soak the pad and it forms to the shape of the metal you are working on, the plastic keeps it wet....works great, almost like it was made for it

Wowser, that is the sound of my mind exploding. Rust 911 is the sheet alright. Nicely done, I am thrilled that I found your channel. I look forward to watching many more episodes in my spare time. Great work. TY so much for creating and sharing your knowledge and experience.

I bought a case of Naval Jelly on your recommendation and it amazes me. I’ll be working on paint stripping one area and have Naval Jelly working on the rust in another and after the second application I look over and the rust is gone.

Great stuff! As a silversmith I call muriatic acid (hydrochloric) a cold pickle for copper alloys and it removes steel mill scale from hot rolled.

I like that phospheric leaves a coating so you don't get instant flash rusting, but muriatic is often way quicker but you just need to remember to neutralize it and wash it off and oil the part.

Thanks for showing the comparison of how the different products work.

Thanks for another great video Wray. The work you do is just amazing.Simon.

Great job Thank you for sharing your knowledge what a talent. This is becoming a lost art. Keep up the great content.

Glad Mark is back. Thanks Wray!

Muriatic acid is really dangerous to the skin, lungs, and any exposed metal, but it's also really fast and really cheap.The baking soda immediately after muriatic acid exposure is a must, because flash rust will happen very quickly, otherwise.

Phosphoric acid is my go to. I use 80 or 90% i cant remember but i prefer it because it leaves a protective film on the steel.

Great video as always. I plan to attend one of your classes as I'm restoring a 84 Caprice Coupe. With a wife and kids it's hard to find the time! Keep the great videos coming! Raynham, Ma.

What an amazing video - congratulations to you and your shop of perseverance - a dedication to rust and form.

I just discovered you, thanks for being here and making this! I miss Click and Clack and your voice reminds me of them. Thanks for bringing back those memories, you have a new subscriber.

To neutralize acid, you've got to use a base. Baking soda is a base, but Amonium Hydroxide is much better (fancy name for Ammonia and water). Rinse, dry, and coat with a water displacer (WD-40 or equivalent). Also, muriatic is cheaper if you skip the paint department, and go to the swimming pool care section of the hardware store. Muriatic also cleans concrete, but be careful.

Oh don't go on about your beautiful, perfect weather up there in beautiful Massachusetts! I'm down here in steamy Hotlanta, changing into my air-conditioned scuba gear so I can walk/swim out to check the mailbox. 😂 It's so hot and humid here, everything wants to either rot or rust away. Last night I dropped a pencil on the back porch. I figured I'd retrieve it in the morning once it's light outside. But this morning all I could find is a handful of compost with a pencil lead sticking out of it. We don't need doors on cars and buildings here, just need 'ports' to pour ourselves into. Have a great day up there Buddy! Keep up the great work. Love your tips and tricks, and Jason's vw (notice the lower case 😆) Thank you for posting your content. Seeing these projects is inspiring, and often has me questioning my impulse to make carbon composite parts (a well formed sheet of aluminum is so much lighter).

Thanks for showing us the Caddy Wray that is going to be a nice ride for sure

I am so fascinated by this. It's transformational.

I used Rust 911 to derust the water jackets on a couple Ford Flathead blocks. Capped off the water pump and set the deck up level one bank at a time. Let it soak about 48 hours and flushed it out. Did an amazing job! Got the idea from your videos.

Great Video! Thanks for the safety tips when using acid to remove rust!

50/50 molasses and water soak works great too. You lose no metal. Love your video! Thanks for all you teach!

Excellent video thanks Wray.

Hi Wray, John from Oz here. Molasses dips work great too. They just take a fortnight or so. Very environmental in that you can tip the tank on the lawn when finished with it!

Very good video. I learned a lot . Thank You, Ronnie.

Wonderful initiative to train the next generation, all the best.

Thanks for the knowledge!

Great vid, really informative, I think you must be the rust King!!

Great video! I am thankful for artists keeping the techniques alive! Thank you for teaching the next generation!

Muriatic Acid is also used to clean mortar from; brick, block, rock, tile, etc. One can neutralize the affects of the acid by using, a Baking Soda mix in water, or even just sprinkle the baking soda over the area or acid.

Jason's killing it on the beetle. Talented guy 👍

What great work all around... very informative,

Vinegar much cheaper and water and baking soda to naturalized the acid in the vinegar some reduce the vinegar but I like it full strength.

I learned a lot. Thank you!

I love the fact that your teaching the next generation i guess you can say thats one of the reasons im teaching myself about cars because ablot of general contractors dont teach a lot of the time because they feel someone will steal their job and when someone is willing it slows down the job a lil bit but then bosses snap

I can't even tell you how grateful I am this is such an amazing video thank you so very much you are an amazing individual with awesome Talent God bless you you are a godsend

I've been working on my 66 Barracuda, thank you I' learned some stuff here :) Been dreading the idea of getting the rust out of the inside of the car, that would be perfect. I was starting to feel overwhelmed by the project, I think the Rust911 will help a lot. I didn't want to just leave it but also baller on a budget :D

It's nice to see a comparison of rust removers.

The VW looks great!🤗

I knew Wray Schelin from United Chevrolet 1979 - He'd compliment a woman by saying she looked "devastating". His yard full of misc treasure. (I remember blue wooden racks from a rack body truck) He'd say ''I'll give you a dollar - to make it legal". Good guy - Nice memories !

Excellent video and info, GOD bless.

brilliant video as always

There are also auto dippers which can dip frames and full bodies. I've used them several times and is a great way to do a full restoration. Great video.

I restore old rusty tools using 'cleaning vinegar'. I just leave them covered in a plastic container for a few days and then wash off the crusted rust that floats to the surface and then wash off this black film that forms on the tools with soapy water, and then either paint them or oil them. Works well and is really cheap. I'm not sure how well it would work on cars unless you had a vat or something.

Bonjour, je regarde souvent vos vidéos et je trouve que vous faite du très beaux travail. Je vous remercie de partager vos connaissances avec nous.

Awesome information I have only just found your chanle, those car's your building are looking good,all the best to you and your loved ones

That sprinkler method is really slick. I like it

You don't have to neutralize phosphoric acid. It only reacts with the rust, not the bare metal. Coating with a diluted mixture is even a preservation method. Look up Ospho, original/namebrand with a bit more extensive how-to.

I was thinking about doing the Rust 911 process for the undercarriage but using an inflatable pool instead. Drive the car on top, inflate the pool and now its all self contained.

Came for the rust removal advice, stayed for this gentleman’s cool accent.

Great information thank you.👍

that Rust 911 is some nice stuff! I'll have to try it on my '71 Plymouth Fury I'm restoring

Gee wray the rust removal on the Caddy did an amazing job compared to when you started, that process works a treat great work mate.

Some real FABULOUS FAB WRK HERE!!

If you use muriatic the warmer it is the better it works. I made pizza steel using HDX from home depot and a plastic tote. It will remove mill scale from plate steel quick. If you circulate the fluid it takes less time.

Great video. Thanks for sharing this. God Bless.

I just stripped 4 layers of paint on my 69 Elco , with CITRA STRIP...check it out. Safe and does not burn or smell. Also...when down to bare metal...I used EASTWOOD FAST ETCH. Now this you need ventilation. The car stayed bare metal for 4 months, before going to paint. It stayed rust free...no rust flashing. You do however, need to follow wiping off Fast Etch, before primer. CHECK BOTH OF THESE OUT. GREAT PRODUCTS....

Acid Magic by Certol, is a very safe full strength Muriatic Buffered Acid. Won't harm skin, but just as effective as the regular stuff!

man am i glad i clicked on this video, i've only got 1/2 gal of prep and etch left only the label had come off the bottle a long time ago and i couldn't remember the name of the stuff, now i just hope i can still get it here in the people's republic of california ..... thanks

I have Muriatic acid. That’s great to know that it works great for rust. I just need to make sure to stray my item down with a baking soda solution and then wash it all alway maybe with soap and water…? It would’ve been great for you to spend some more time on that part. But I’ll look into it further thanks!

Bloody awesome!

Awesome info really appreciate it

I can't wait to see your videos

Ray, much thanks for sharing your expert knowledge. I must add that VINEGAR works miraculously well on CAST IRON. I have an ancient cast iron waffle iron from the 1600’s - 1700’s and upon applying VINEGAR to its heavily rusted exterior, the VINEGAR had a major reaction with the RUST. It left a heavy crust like precipitation that actually served as an armored shield to prevent any further rusting. I was amazed to discover that after 8 years the crusty precipitate comes and bare clean cast iron is underneath it.😃

Just a tip to anybody that uses the muriatic acid. Wear protection. If you add water to the muriatic it can react aggressively. I use it to clean out rust plugged drain pipes. I do add hot water to get it going faster, but it will fume up with cold water also. I use it to clean rust off of concrete also.

Thanks Wray

Stumbled on your channel, I have been looking for this type of rust removal, what's the ratio on the baking soda and water? How do you neutralize the acid, thanks, great video.

Cool. That rust 911 is impressive. Spraying this car would cost a little more then a sand blaster but in the long run much cheaper this way. Very cool idea

Make it custom put me onto you Wray , love the channel , I feel some binge watching catch up coming ,cheers

I think it's interesting how acids are categorized as corrosives yet they remove the corrosion. However I've seen muriatic acid remove rust and if left for too long will simply dissolve the steel away. Of course there is also soda blasting.

Once the rust is off is there anything else that needs to be done before primer is sprayed on?

Thank uou sir, looking forward on my 37 Dodge Coupe floor, foot rest panel etc.

I just coming to the end of derusting a gas tank from a GMC class c r.v. and I'll tell u these things that was learned with electrolysis rust removal 1) dial up power, if I could Dil up the amps from the battery charger it would have gone faster. 2) baking soda - refresh after every 24 hrs, and yup that's after cleaning electrode 6 times in 24 hrs, 3) size of sacrifice steel - because it's an internal job through sending unit hole I should have made a T bar set up to easily reach the side of tank, 4) using tranny fluid to seal the rust inside the tank just dump about 4 liters or a gallon of tranny fluid in roll it around cover everything, works amazing keeping new rust at bay, and just before installing tank draining the excess oil out careful watch for extra chunks lol they will appear outta no where l 5) cost yes saved me hundreds for a new tank which I don't have lol but time line well learning hard way lol, So just remember thickness of sacrifice steel and type of steel, refreshing and flushing of part, power i.e. amps not volts ! Lol, and cleaning of rods.

I noticed you using steel wool what grade is it? and is there any other scrubbing materials (Have the scotch bight)?

There's another method of rust removal that I didn't see mentioned here. Electrolysis. It leaves metal looking much the same way the Rust911 does. Zero chemicals involved.

interesting shop, thank you

Brilliant video thank u 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

Mix Molasses exactly 1 part and 9 parts water... Put in huge bathtub..lay down your rusty parts. Pressure wash it after 2 weeks.. Repeat the process in the same bath . Now its like brand new

Nice. I wasn't aware of muriatic acid for rust removal but I've played with lots of other methods. I see you're also having trouble with those ZEP sprayers. They just don't last long, even with water.

It looks like you have a lot started but is anything moving out or finished. It almost seems like your students coming through are doing all the work. Brilliant.

some good info. thanks

What are the products to mix?

I'm close.to you, here in Hampton , NH ,I've done a woodcarving of Benoit Musy driving a Maserati 300S , fantastic curves to carve!

Hi Wray, what attachment are you using between the spindle and the shrinking disc backing plate on your makita? Bending the radius and dent repair video

Awesome!

Have you ever tried citric acid? Granules mixed with water...soak submerged. Works great.

The phosphoric acid is the best since it won't eat in to the metal, and muriatic is hydrochloric acid (HCL) and chlorine is corrosive. Better option is to brush on phosphoric acid, cover with plastic, and wipe after about 15 minutes. The other advantage of phosphoric acid, is that creates a rust resistant barrier that protects the metal and also preps the metal for paint. Phosphoric acid is a wonder compound in my opinion. I use it all the time, even as a degreaser on metal and for paint prep on non rusted metal surfaces.

I have tried the rust 911 and it is great. I got the rust off of a set of VW bus rims and small parts before I ran out. Going to get more to do other parts and another set of rims. Question: what prep work is needed to paint after Rust 911 use?

First Thanks for sharing your knowledge. When rinsing your panels try using hot water or steam genie. Typically the flash rust can be avoided.

Thanks for the good video.
