Re: Citric acid bath.....amazed at the out come!

Great job, for sure!
Just wondering about the obviously missing step of "neutralization" of the frameset.
For example:
I`ve bathed an old two-tone D.I.D. chain in a citric acid bath a few weeks ago.
Comes out great, so I`ve dryed the chain before storing in a Plastik bag together with chain oil.
But after a few hours some areas started to show surface rust yikes
In fact the rust grows really speedy!

I`ve searched the internet for possible explanations.
Then I`ve found the hint to neutralize the citric acid bath before removing the bathed parts.
After this I`ve made another citric acid bath to Gerüst the chain again.
At the end I`ve added "bicarbonate of soda" (Natron) to the bath to increase the lowered pH-valide again to normal.
As a result the chain doesn`t show any effort starting to corpore again like before smile

What did you put the frame in when you soaked it? I've got a Pro Freestyle Tour I need to do that to!

For some reason I can't post pics. But I used a clear tote you use for clothes. In Canada you can get them at Canada Tire or any Hard whare store.

Thanks.....To be honest I think I just wiped it off, still looks like the same as it did when I first did it .

Yes it is in powder form. I bought mine off ebay.
Here's what is did with a 1976 R&R I cleaned up a few years ago.
It didn't hurt the decals at all. And i used powdered citric acid because vinegar can be too harsh on certain chrome finishes so i definitely din't want to eff this frame up. i got my clothes storage container from a garage sale for a buck.
