I would paint them....but I would just take the doors down and remove the hinges from the doors and paint them separately....that way you don't run the risk of getting paint on the cabinets.

I am really more concerned with what color to choose for the hinges. Do I go Oil Rubbed Bronze with the hardware being Dark Brushed Antique Copper. If I am to get the Antique Copper look, it will take several steps to spray paint, too!

Any of these work?

I'd do ORB. By the way, I had those exact hinges on my cabinets at work and rather than buy all new I spray painted them. It's been a year and no one would ever know that they weren't always satin nickel.

Jakuvall - Unfortunately none of those hinges will work, since I need demountable hinges. Thanks though.

There is a product called Rub N Buff that will transform the color of metal. I used it on a frame before but I was also thinking of trying it on some cabinet knobs. I dont know how it would hold up to everyday use. Google images of Rub N Buff kitchen hinges. One woman said she sprayed the hinges with Glossy Clear Protectant Seal after the Rub N Buff as she did all of her kitchen hardware with it. It would be interesting to hear how this stuff is holding up over time. It is doing fine on the frame but that hangs on the wall and it is not something that you constantly touch.

I forgot about Rub n buff! That's stuff is fabulous.
Of course, you can take the doors off; I was being lazy. :)

I think since one pretty much never touches the hinges, either way would be fine. I'd just use a light touch when dusting.

Yeah! ORB or a hammered copper is my vote!
BTW. It's paint. Try both.

I will definitely try the Rub N Buff...going to go out tonight and get some. This may be my weekend project. Thanks everyone for the suggestions.

Please post how they turn out.
I want to change my brass knobs in my kitchen and since I have open concept I will have to change out the entire downstairs of my house. That is 154 hinges so pretty expensive to change out. I have the same demountable hinges you have.
