Have been using this recipe many times (found it on another channel) and it works really well and lasts much longer than Evaporust. The only thing to be aware of is that it dissolves zink. Brass, copper and aluminium seems unaffected.
After a good de-rusting be sure to rinse and quickly oil up the parts to prevent flash rust. WD-40 works fine unless the part is to be painted. For that just get primer on, but be aware that primers are porous and just slow oxidation until actually painted over and sealed from the atmosphere. Yes, warm/hot water and ultrasonic will speed the chelating process considerably. BTDT 10/10 on the video.
Nice end results. But if you look closely, the muffler has a lot of metal gone (holes) from the rust around the treaded part. So it may not be long before it is gone... Thumbs Up!
Perhaps the Chemical equation is: H3C6H5O7 (citric acid) + 3Na2CO3 (sodium carbonate) → 2Na3C6H5O7 (sodium citrate) + 3H2O (water) + 3CO2 (carbon dioxide) But molar mass and actual mass added to the water probably leaves it with a pH
Interesting! Great results. Only issue I have is that it gets spent. Evaporust lasts a very long time. Adding an air stone will accelerate the process.
So you dissolve citric acid in water to have an acidic solution, you partially neutralize it with sodium carbonate, you are left with water, smaller concentration of citric acid and sodium citrate. You could have just used less citric acid since sodium citrate is having less weight in the rust removal process.
You can find citric acid at most hardware stores (or Amazon) and sodium carbonate is washing soda, which can usually be found in the grocery with washing detergents. I live in the USA, so take that into account.
Citrus is massively too expensive to waste on rust removal. That would take approximately 20 lemons - $30 Canadian where I live. The citric acid is $2.
I also use citric acid for rust removal and for things internet says "vinegar" instead, because I hate the smell. I've found that adding heat makes rust removal significantly faster, you don't have to wait overnight if you're in a hurry. Best commercial rust remover I've used is Bilt Hamber Deox-C, it's also in powder form, and gets faster when the solution is heated.
your just using a weak vinegar to remove rust the baking soda kills the acid in the vinegar soap does let it stick yes you want to remove rust evapo rust is your only option.
@@anasalwash it's not completely neutralized since he is using 0.52mol of citric acid vs 0.38mol of sodium carbonate. So there are still free H+ ions, but less than before. Is it useful? Probably not.
I would think Evaporust and electrolysis would be a better solution than having to wait so long with that process. But it looks interesting regardless of the situation.
One problem. The mixture got neutral with both ingredients. I've done it with the acid first and then the baking soda. Reverse PH knocks the rust of big time!
Thank you AJ!
Thank you Beyond Ballistics!

I've used this solution, my experience is it it way cheaper and removes rust over many more uses than evapo rust or any other thing I've ever tried.
That’s amazing AJ, I’ll have to give it a try! Thanks for sharing!

Thanks, it is a very helpfull as we all have some rust removing to do.🐞

I want to try one of the Lazer rust removers too!!!

Correct, that is the video linked in the video description.
Attach magnesium after cleaning to stop corrosion. bake baking soda on glass and it turns to sodium carbonate needed here.
This is beyond ballistics formulation
Correct, its where I found it. I had to try it for myself.
Good info!
Interesting! Great results. Only issue I have is that it gets spent. Evaporust lasts a very long time. Adding an air stone will accelerate the process.
With hevily rusted parts Evaporust also gets spent quickly. My Evaporust sollution got spent with the 3rd use. Its not worth the money.
Good morning from Southeast South Dakota AJ
Ah. You made Enos 😂
I will try this mix.
Phosphoric acid works very well.
So you dissolve citric acid in water to have an acidic solution, you partially neutralize it with sodium carbonate, you are left with water, smaller concentration of citric acid and sodium citrate. You could have just used less citric acid since sodium citrate is having less weight in the rust removal process.
I was thinking the exact same thing.
@@dreimer2 me too, it makes little sense unless you like to watch the reaction... lots of bubbles
You should probably stick with Evapo-Rust
Isn’t it an acidic buffer solution ?

Very nice A.J.. Where can I purchase the ingredients to make up a batch of that?
You can find citric acid at most hardware stores (or Amazon) and sodium carbonate is washing soda, which can usually be found in the grocery with washing detergents. I live in the USA, so take that into account.
@pfadiva is correct, its easy to come by for most.
@@pfadiva thx for the info... I'm in the states also... Should be easy to find it...
I want to try one of the las
hydrochloric acid works much better and fast.
and vinegar or citrus acid pure works also ok..
cheers

Citrus is massively too expensive to waste on rust removal. That would take approximately 20 lemons - $30 Canadian where I live. The citric acid is $2.
2.2 pounds of Citric Acid cost me $5.66 and it will make 10 liters of solution. Its really damn cheap comparing to evaporust
@@AJRestoration vinigar is a little bit cheaper and give the same result.
but for quick result hydrochloric acid is very good.
I also use citric acid for rust removal and for things internet says "vinegar" instead, because I hate the smell.

Thats some good advice! Ill give it a shot. Heating it up makes sense.
@@AJRestoration Heat and an ultrasonic cleaner speed it up by about eight times.
Looks like it will even remove the carbon from the inside of the muffler
Have you tested just Distilled White Vinegar? I use it for fuel tanks and it can do that in about 1 hour.

There is a better and cheaper solution than Evapo-Rust for removing the rust, and it is called: Deox C
It is made in U.K. and it works amazingly well.
incorrect
th-cam.com/video/fVYZmeReKKY/w-d-xo.html
so, the only active ingredient is the soap since the acid and base neutralized each other
nope

oh dear. oh dear. oh dear.
ElementalMaker had the exact same recipe but explained the process as he went .

Elemental Maker used EDTA. Not the same.
Oh No
