No, that would be too strong, you're looking at vinegar level stuff. Warm vinegar can work, play on another blade first see what you can get with the color.
I'm only a casual amateur that toys with stuff every now and then for fun, so I can't really give you very precise instructions, just point you in a general direction.

Look up past forum threads from this section as well, there are people who have experimented with this a fair bit. Or start a thread about it and somebody will probably help.
