Cold blueing

[Robert1998]

Hi everyone.

I have usually use birchwood Casey cold blue. You apply it and rinse thebpart in water.
The results are not great and it is expensive.

I have seen some videos where the parts are soaked in the solution. I have seen this product with 2 solutions (2 steps)

The link is in Spanish, but you will get the point

What do you think?

Thank you

Best regards

The link looks like it has nothing to do with cold blueing. The screen text, and the actual link itself are different, so this is very dodgy. I'm not even going to follow it!!

It is to a digital oscilloscope, how weird.

I've used this and seems to work fine, not sure if you can get it in Spain.

I’ve used Casey’s cold blue before. Things have to be very very clean to get a good result.
