Serious rust removal!

The whole chelating thing is over my head so I'll just take your word for it.

 

That ok Saxman... I'm short so most things are over my head.
I'm basically lazy so I love how I can leave something in the solution and not have it eat the good part.
Hmmm wonder if you could make iron-fortified cookies with it after?

 

Exactly right, some spout forth with out thought.

 

My only thoughts are you will get rust through with the severe pitting. Ask me how I know.
I used an old chest type freezer as a molasses tub, free and worked great. No the molasses wasn't free just the tub.
But if the rust through s are there ,well they are there!!

 

I also use a chest-type freezer.

I also sometimes build a container "free-form"....
Concrete building blocks in the shape of what I want to clean.. lined with either super heavy plastic or pool liner or.. believe it or not, large old air mattresses cut inside out.
They have a lot of little cross pieces that need to be cut but they are water proof.

I've done that for electrolysis as well.

Kiwi 4d .. I would think you would get rust through with any method that removes all the rust if the pits were deep enough, wouldn't you?
Or (like often happens) am I missing something?

with the electrolysis method would you remove the lead from your panels 1st? i hate lead with avengence.

 

Chemical dipping on my body shell and panels was awesome ! I didn't think $2000.00 was very expensive at all for super clean metal, I know it's not in everyone's budget , but it sure beats the hell out rust,caulking , lead, paint, sound deadner and so on. I would do it again in a flash!

 

Once you use Citric Acid,you will never go back to Mollases,this stuff comes in crystals,it's enviro friendly ,no mess,no smell and the results are amazing,hope this helps, Gaz!

 

I use a stock tank that isn't steel construction. That gives me a 3' by 4' area to work in, I use the 300 gal size

 

I know this thread has been done for awhile, but I'll still chime in. I thought molasses was a crazy idea, but I thought I'd try it anyway and was super impressed! I used phosphoric acid with good results. Sand blasting and lots of grinding / sanding. This is much easier. I mixed it 1:9 with water and after two weeks everything was clean. Next is to set up a spray / drip system for my main body.
