How do you degrease before etching/coating/blueing, etc? I have been plauged by uneven results with just about every etching process I have tried, regardless of how I degrease. I think my biggest problem is actually minerals in the tap water, but I want to be sure I am using a cleaning method that works well, if I have to start buying my wash water at the store. I am etching in ferric from Radio Shack, diluted 4-1 in distilled water, and immersing the blades for approx. 3 minutes.
The temperature of the ferric bath is fairly low, I know this sometimes affects how agressive the etch is. There is also no aerator or equivalent in the etch tank, I agitate the blades every minute or so during the soak. I did 3 blades yesterday, 2 came out fine but the 3rd got 3 treatments and came out with different patterns of light/dark areas each time. Fixin' to pull some hair out if I can't get it right today
