Have you tried a different brand of distilled water? I know it sounds weird but Iíve had some brands that didnít work.  Never did understand why.

Iíve been having very good luck with Mark Leeís express blue.  I did a barrel, 4140 steel, last Monday a week ago, 3 hours start to finish and got a very nice blue/black finish.  10 cycles using scotch-brite to card and I can rub as hard as I want and doesnít go through the blue.  Had a conversation with Mark Lee last week and he doesnít even plug the barrel anymore using this, but does not blue the muzzle, just polishes it when done.

Waksupi-always nice to hear of others that have successfully changed to steam.  I tried a longer steam a couple of times and didn't seem to get change after 10 minutes.  Does your longer time give you a faster or deeper color?

I believe it just benefits completing the change of the processing. For more color, more cycles. I usually repeat around a half dozen times. The lighter the layer of oxidation, the better the results.
