We frequently
receive emails asking for information on locating parts for restoring lanterns
and other railroad artifacts.
Railroadiana collector Rob Hoffer compiled this collection of tips
from many collectors. The opinions represent the experience of many
collectors, and are offered as suggestions. See Thanks to all the
collectors who contributed information. Your milage may vary.
Brass:
BRASSO has worked fine for me in cleaning up brass nautical items.
For big brass jobs I use a strong janitorial supply called KRC-7.
It can be ordered from Chemique Chemicals in Moorestown, NJ and
is pretty reasonable. It can be diluted for the faint of heart.
It's pretty strong phosphoric acid with a few unmentionable elements
added. However, it is the only strong product that will not turn
bronze a pink or coppery color. It brings out the yellow in the
brass. It is suitable for large jobs and works pretty quickly
at full or near-full strength. Fine steel wool works after rinsing
the acid off. Rubber gloves are a must. Chemique also makes a
bizarre little chemical that you can wipe on with a cloth and
the brass will not tarnish, even when handled. They're in the
phone book and will send order forms upon request.
For non-plated brass & bronze items, I use a DILUTED solution
of Muratic Acid, available at Home Depot, Lowe's, Home Quarters,
etc. for about $2.00 a quart.
Mix the acid with water (30%/70% respectively). Take a rag, dip
it, and rub lightly. The acid will work immediately on the corrosion,
and you will immediately get a light, copper colored tarnish.
Take another rag with Brasso or other brass cleaner, and apply
it to the bell. You won't have to rub hard, and the copper-colored
tarnish easily comes off, leaving a beautiful even patina to the
item. Wear gloves and goggles!
I'd do a test patch first. Might get a pink bell. Naval jelly
will be better, but the stuff I use is best. Bells don't have
much copper in them, so pink metal might not be a problem. However,
a bronze whistle or any type of valve brass is usually another
deal.
China:
Hydrogen peroxide is a traditional weapon in the conservator's
arsenal. It's the favorite bleach for removing stains from paper,
and is very good a bleaching items with lead-based pigments (it
works great on white lead). It will work on china, but probably
very slowly.
Chlorine bleach will work more quickly on china, but most store-bought
chlorine bleach preparations contain additives that will soak
into the piece if allowed to sit in the bath for a prolonged period
of time. Oversoaking a piece will tend to weaken it.
Chloromine-T is a dry-powder chlorine bleach mix that is often
used by professional restorers. The product is additive-free,
and can be purchased through industrial supply companies. While
this is not as powerful as clorox, it won't contaminate the china.
When treating an item, soak in cold solutions only, do not oversoak,
and soak the item in cold water when you are finished to rinse
away remaining chemicals.
Another way to clean china although not really cost effective
is to use over night denture cleaner. An older collector that
I know tried this and he said that it worked good.
Locomotive Bells
Polishing a bell may not be as hard as it looks. I've done two
recently and offer the following tips. if the bell has paint on
it get this off using any commercial grade paint remover. next,
apply naval jelly in areas about 6 or 8 square inches at a time.
let it set for about 20 mins then wipe off with a damp rag and
wash off completely. it will not hurt the brass and will get through
most of the heavy corrosion quicker and better than something
like Brasso, which is only a polishing agent, not a cleaner. after
you've removed all the "green" or heavy dark tarnish
(this may take several doses of the naval jelly) go after it with
something comparable to NEVR-DULL a cotton wadding polish and
cleaner. again, work small, manageable areas at a time. when you
finish this step you may only have to give it a final shine with
Happich semi-chrome if you can find it or Blue Magic. both are
polishing creams and i buy my Blue Magic at a local hot rod shop.
they sell it for shining up chrome on cars. I have a Texas &
pacific bell in my office that i shined up using these steps and
it draws great reviews from even non-railroad types. this is a
long process; don't get in a hurry.
I have done two locomotive bells. I have a lathe big enough to
handle the bell casting, so I chuck it up and rotate it at a fairly
slow speed. If the tarnish etc. is quite bad, I first will use
a very fine sandpaper, (no coarser than 320) to clean the bell,
holding it against the rotating casting. I personally use a small
"flap wheel" on a little angle head grinder. Then, I
use a cloth buffing wheel on the grinder, and polishing rouge,
starting out with black (coarse grade) compound and then a final
polish with red (fine grade)compound. This will give you a beautiful
polish on your bell. If you don't have access to a lathe, you
could do the same thing on the bench, just use a little care to
keep your polish "even".
One addition: Work naval jelly with an old toothbrush before
washing it off. this helps break up stubborn spots. remember,
naval jelly is a mild acid so don't leave it on too long at a
time. do two applications if needed.
I washed the thing down and scrubbed it with Revere Ware Copper
Cleaner and a "scrubby thing that I snitched out of the kitchen.
This worked OK but, not good enough. I ended up going to the hardware
store and buying a buffing thing for the drill and some jewelers'
rouge. After I gave the bell a shot of paint remover the buffing
wheel and rouge seemed to work *MUCH* better. It took the better
part of all day to spruce her up. Lastly, I gave it a shot of
Happich semi-chrome which brings out the shine real nice and repainted
the yoke, clapper, and base with high gloss black paint.
A word of warning - NEVER - NEVER - NEVER repaint the inside
of a bell! This is a tip that it is old. It's like cleaning the
back of builders plates - NEVER do that either.
Silverware:
For fine stuff like silver plate, Twinkle (brand name) silver
or copper cleaner depending on material. This good cleaner will
take off the light tarnish that comes from humidity. It will also
leave a light tarnish inhibitor.
Revere Ware Instant Copper / Stainless Steel Cleaner. This stuff
works like a top on heavy copper or brass stuff. It is *NOT* recommended
for light silver stuff as it seems to be fairly abrasive.
"Never - Dull "The Magic Wadding" polish. This
is also a *GOOD* cleaner / polish combination. It is good on most
metal objects and I have used it on everything from bells to whistles
to lanterns to silver plate.
Simichrome Polish: This is in my humble opinion the *BEST* metal
polish on the market today. It is *NOT* cheap. But, it does not
take a lot to make a piece of silver shine like new money. The
shine also seems to last for about a year. A tip on this stuff
would be to use small amounts at a time.
I would like to add Hagerty's Silversmiths' Polish as one of
my favorites. It is a liquid and is non abrasive. It also contains
a "tarnish preventative". I have used it on fine silver
plated instruments for over 20 years. It doesn't "cut"
as easily as "Simichrome", which is my first choice
for really tarnished items. The only drawback to some of these
paste and liquids are the residue left in detail work.
There are also a variety of "Silver polishing cloths"
which are good for "maintenance". They are soft and
non abrasive and will remove light tarnish. Again, safe enough
for fine silver plated musical instruments.
I agree with all, except the use of Simichrome. There is a reason why
it works so well and why it takes so little time to clean . . . it is,
by all accounts, incredibly abrasive. I am told by those who work with
metal that in addition to some very harsh chemistry, it also contains
silica/silicate (in the form of finely ground glass) as well as extra
fine pumice (the stuff they use in Lava soap) which could rip the hide
of an elephant. I have had collectors who have used Simichrome over a
period of years see noticeable wear/damage to side marks on silver pieces.
I will add, that a friend who collects railroad flatware, recently
purchased a "device" he saw advertised on television.
It uses a metallic surface which is placed in a basin along with
warm water and detergent (as I recall). This sets up an electronic
effect that removes the tarnish. He said it works well, and that
he can clean hundreds of pieces of flatware in an evening. Have
not seen it first-hand, so can't comment personally.
Also, don't forget the old stand by, Brasso (a bit abrasive,
but puts a shine on brass tops like nothing I have ever seen),
as well as A-OK Metal Polish which works well on nickel plating.
For the benefit of everyone, please do not use the old "vinegar
and salt" method to clean brass. It does work, but you might
as well take the item and rub it on a concrete sidewalk, it will
work as well, and is equally as abrasive. Also, if you own a steel
wire brush, throw it away. I have seen many great lanterns and
locks ruined by using this technique. A very fine/soft brass brush
may be OK in certain circumstances, but not often. Nothing beats
non-abrasive cleaners, soft cloths and tons and tons of elbow
grease.
