By now I've mixed up a few gallons of this stuff. I sat these headers in it for a few days and they cleaned up rather nicely. I wasn't able to keep all of the headers in the solution all of the time but it worked well. A little final clean up and paint and these will be back to new.


I've also been working on a turbo housing. Those things are very rusty and the one I'm working on is about 25 years old. It is taking a little bit of work but I like it better than trying to sand blast it and then hope the sand gets all cleaned out and you don't toast a bearing.
