How to dull a shiny nickel finish?


A discussion started in 2007 but continuing through 2019

2007

Q. Hi,

I am a home owner from South Africa. Most of the metal door handles in my house are finished to nice satin / brushed look. New doors are added, replacements are made. For unknown reasons our local suppliers cannot provide me with new door handles of the kind I have in satin finish - only the shiny look, so I ended up with several which look odd and are difficult to maintain. Is there a DIY way to dull / matte the shiny nickel (chrome?) finish. BTW, I am a chemical engineer and my wife is a chemist so we may be able to do some advanced DIY in this respect.

A. If handles are nickel plated you can blacken them with next solution:
1 lit water
0,5 gm potassium thiocyanate
5 ccm sulphuric acid
25 ccm hydrogen peroxide(30)
15 °C temp.,15 min. immersion

If handles are chromium plated oil them with any edible oil or fat (very, very sparingly) and then heat them to 300-400 °C (slow-with hot air gun). Hope it helps and good luck!

Dulling shiny nickel plated hinges

June 6, 2019

Q. I bought 26 brushed nickel pulls for my kitchen cupboards that can't be returned and now I need to match 52 showing hinges.
How can I dull these hinges?

A. Hi Chris. Getting bright nickel to match brushed nickel will be quite a trick. Bead blasting the shiny nickel plated hinges might be the most promising approach. Other than that you can lacquer them with a matte lacquer to reduce the reflectivity.
