Paint stripper is applied to brass
drawer handles to remove the original coating. The parts are
brushed with tarnish remover, then rinsed and buffed on a
wire wheel. The handles are sprayed with lacquer to protect
the finish. |

Start:
Before
refinishing, the drawer handles on this dresser
had become quite tarnished.
They didn't look
bad against the original medium-brown stained
wood, but I stained the wood a deep red color,
and I felt the handles needed a cleaner look. |
 |
|
 |
I removed the screws on the inside of each
drawer and pulled the handles off.
These handles are
brass-plated metal, not solid brass. I wanted to
make these handles look better, so I decided to
try to remove the tarnish. |
|
I understand that a lot of brass
hardware is coated with lacquer to slow down the
natural tarnishing process. Dried lacquer can usually be
removed with lacquer thinner. The first thing I did was put
the handles in a plastic cup, pour in some lacquer thinner,
and brush the hardware with a paint brush. The solvent got
plenty dirty, but there was still some gunk on certain
parts. I couldn't really tell if the coating had been
removed.
Then I applied some paint stripper to the
handles, let it soak for about 15 minutes, and power-washed them.
This removed the gunk, but the tarnish still remained.
I put the
hardware in a dishpan and squirted some Brasso®
on the metal.
|
 |
|
 |
Then I used an old paint brush to dab the paste
around.
|
|
The Brasso
paste started to dry out after a few minutes.
Since the label stated that it contained
ammonia, I decided to try adding some household
ammonia to thin the paste. After some brushing,
the ammonia mixed completely with the paste. I
was able to create quite a "lather" after a few
minutes of brushing.
|
 |
|
 |
After about 30 minutes of soaking in diluted
Brasso, I put all the handles in a plastic crate
and washed them with a garden hose.
|
|
When the
handles were dry I buffed them on a wire wheel
mounted on my bench grinder.
However, I
discovered that it was easy to buff through
the brass plating, so I had to keep the
buffing to a minimum.
Wear eye protection if you do this. I
once had a wire wheel buffer throw a piece of
wire in my face. Stuck right in my forehead. |
 |
|
Buffing small parts on a wire wheel
can be tricky. If you don't hold the part tightly, the wheel
can rip it from your hands or jam it into the guard.
I suppose a small fine wire brush could also
be used for this, but that sounds like a lot of work. If the tarnish
wasn't so heavy, I could've just followed the Brasso instructions
and applied the paste to a soft cloth and rub until the tarnish is
gone.
A Confession:
Before I took these pictures, I did some
experimenting with other chemicals for removing the tarnish from the
brass drawer handles.
I wanted to try soaking a handle in strong
acid, so I poured some CLR (Calcium-Lime-Rust Remover) in a dishpan
and let a drawer handle soak for about 15 minutes. I'll note that
the instructions say "do not use on brass or copper", but I
used it anyways.
 |
The handle on top was given the acid bath. Note
that the acid didn't remove the tarnish, but it
did change the color of the brass. I'm guessing
that the acid attacks the zinc near the surface,
leaving more copper and giving the reddish
color.
The handle on the bottom had been
cleaned using Brasso, then buffed on the wire
wheel. |
|
I set each
handle on a finished drawer to compare the
color. I liked the reddish-brass better, so I
decided to acid-treat all of the handles.
|
 |
|
 |
I put all 16 drawer handles in a dishpan and
poured in some CLR. Actually I used Home Depot's
ZEP brand of Calcium-Lime-Rust remover, which
works just as well and cost less.
I didn't
even have enough liquid to cover the handles
completely, so I used an old paint brush to dab
the acid around, making sure each handle
remained wet. |
|
Warning: Acid Can Be Harmful!
If you use any type of strong
acid, you really need to wear rubber gloves and eye
protection. A face shield is even better. It's really
easy to splash a few drops of acid on yourself. If you
do, rinse right away.
Use with good ventilation. I did this work outdoors, so the smell
wasn't a problem. |
|
After the handles were dry, I installed one
screw in the back of each handle and made a "hang-hook" from a piece
of mechanic's wire. I just wrapped the end of the wire around the
screw head, and bent the other end to form a hook.
Then I set up a hanging rod in my
basement to hang the handles from while I spray-finished them. I
just supported a 10-foot piece of pipe from the floor joists, using
bungee cords to hang the pipe from a couple of nails.
I poured a
couple of ounces of nitrocellulose lacquer into
a plastic cup and thinned it about 25% with
lacquer thinner. I poured the thinned lacquer in
my spray gun and sprayed each drawer handle.
I'll note that lacquer is available in ordinary
spray cans. |

Here's a better picture of my 5-minute support
apparatus. You can see the blue bungee cord at
the upper right.
After I sprayed all the
hardware with lacquer, I let them hang for half
an hour while they dried. Lacquer dries very
fast, but it's not as durable as urethane.
When the handles were dry, I removed the wire
hooks, and they were ready to be re-installed in
the dresser. |
|
After
refinishing, the brass drawer handles looked
much newer and cleaner.
Maybe some people
prefer the "rustic" or "distressed" look of the
handles before I removed the tarnish. That's
understandable.
I felt that the original appearance didn't do
justice to the color and quality of the
refinished dresser. |
