Here is the text from a book of mine - British Military Swords 1786-1912 An Illustrated Price Guide for Collectors. It tells you about how to preserve and look after your antique swords. Hope that you find the information helpful!
The correct care and preservation of a sword is not an easy task. Many a fine sword has been ruined by overzealous cleaning and poor attempts at amateur “restoration”. If you are new to this field of collecting, the basic rule is:
IF YOU ARE NOT SURE ABOUT HOW TO PRESERVE YOUR SWORD, OR FEEL THAT YOU DO NOT HAVE THE NECESSARY SKILLS TO COMPLETE THE
PROCESS, ASK SOMEONE WHO DOES.
This “someone” might be a fellow collector with experience of restoration, a dealer who might be able to tell you him/herself, or “knows a man who knows a man“. As time goes by, you will meet people who can offer sound advice. They will be speaking from years of experience, including mistakes that they themselves made at the start!
If the restoration job is complex, it is always better to hand over your sword to an expert restorer and let them do the tricky work. Expert restorers can be found through word of mouth via dealers and collectors, and some advertise through related militaria journals and magazines. There is also a lively circle of dealers and collectors who speak to eachother through internet web sites devoted to collecting edged weapons (see page 176), and they are always more than happy to exchange tips and contacts.
You might think that after paying a considerable sum for your sword, the very last thing that you are wish to do is spend even more cash. This attitude is wrong, and if you intend to keep and preserve a fine collection of British military swords, a little extra spent on preservation will be a sound investment.
Saying this, I do not mean to frighten away the collector by saying that they cannot or should not do any kind of preservation work. Far from it. An expert should normally be called in when there are complex or detailed areas of preservation or restoration work to be addressed, particularly when this might require the sword to be taken apart or broken parts to be repaired. I have visited too many auction rooms and fairs to see the results of amateur botched repairs to hilts, blades and scabbards. Here are some basic emergency procedures that are relatively simple to undertake but vital if wishing to hold back the ravages of time, and ensure that the sword does not deteriorate any further.
BLADES AND METAL
SCABBARDS/FITTINGS
One of the first problems that you may encounter concerns the accumulation of corrosion e.g. rust. The use of a Break Free oil which dislodges the rust is recommended, but not on blades with blue and gilt finish, as it has been known to loosen the gilding. Alcohol or kerosene is light enough to clean these delicate blades, and when completely wiped clean of this, a covering of fine carabellum wax is applied. This provides a protective seal which keeps out moisture.
There are a number of specialist waxes on the market. I recommend Museum Wax or Renaissance/Becketts Wax. All these products are available from specialist hardware or gun supply shops, and a quick trawl through the internet will also locate a number of merchants who can supply mail order.
Vaseline petroleum jelly or pure mineral oil/gel will also protect the blade from future moisture, but it is important to stress that you will need to inspect the sword on a regular basis to see if any rust or corrosion has returned. Some swords have very heavy areas of rust where the use of Break Free might not be very effective and other options need to be considered.
In these cases, a very fine abrasive might be used, but you must decide whether the blade etching or hilt/scabbard plating might be damaged or worn by this method. It all comes down to how you want the sword to look, and there are some collectors who cannot resist removing the age or patina of a sword because they believe that a highly polished sword is more attractive. Thankfully, there are not a great number of these individuals, but you will continue to see swords that have been polished to a gleaming state and there is little you can do to return its character. Do not let this be a reason not to buy a particular sword. I would rather acquire a highly polished but rare piece, than none at all!
Another important point to remember is that constant handling of the sword will endanger its condition, especially when moisture from hands comes into contact with the blade. Any collector of Japanese swords will testify to the permanent damage to the blade that can result from fingermarks that have not been immediately removed. The wearing of lint free cotton gloves might sound a bit drastic but it ensures that the sword is kept dry. Remember to invest in a couple of pairs. This ensures that there is a spare pair on hand when that inquisitive friend pays a visit.
HILTS, SCABBARDS AND
LEATHER / FISHSKIN GRIPS
A toothbrush and some ammonia detergent or soapy water is effective in rooting out dirt and grime from recesses in hilts and scabbard mounts. The main priority is to save any original gilding, so do not use any abrasives in this area.
Use a good leather care product on grips and scabbards to avoid drying out. It should also have a high wax content as it will act as a long term anti-drying sealant. Regular inspection of leather fittings should be done in conjunction with the inspection of the metal parts. Try not to display swords with leather scabbards or grips too near areas of heat, particularly central heating radiators. It is probably stating the obvious but direct sunlight will never be advantageous to an antique piece. For fishskin grips I recommend a little baby oil or olive oil to allow the material to breathe again. Do not rub too hard on grips as they can be very flaky and pieces can easily come away.
