I’ve used Brownells Oxpho-Blue before on various non-gun parts (tools, parts of tools. etc)
I would heat the part before dropping it in the solution, (swish it around in the solution)
once done rinse it very well with water, dry it well, then oil it to preserve the finish.
My results have come out very well, though lately, I’m becoming a fan of Cerakote type finishes.
That being said…
I got poisoned by chemicals in the Navy so now I’m cautious. I wear rubber gloves and
work in a well-ventilated area and/or wear a respirator, to avoid unnecessary exposure.
If at all you can avoid hazardous chemicals then it’s best to do so,
but if you need to work with them then always take the proper precautions.
I cringe when I see the way some work with chemicals having dealt with the long-lasting
health issues they can cause. It’s always best to err on the side of caution, a bit of
protection now is far better than dealing with the health issues later.
