Cleaning by hand

Cleaning, the Gun and Column Components by Hand

When cleaning by hand the gun and column components you may use any metal polishing media that is suitable for brass or stainless steel and preferably soluble in dilute ammonia, DO NOT use a media that is said to be "long life" as this will place a polymer coating on the components (the applicable solvent is acetone). The solvent dilute ammonia is a mixture of 1:10 ammonia solution (40°/o) and water, it is a solvent for tungsten as well as for media like Bluebell, Silvo or similar. Use a sharpened stick with cotton or tissue spun onto the end for cleaning difficult areas. But, take great care if you are using sharpened sticks, the only sticks that will not break are bamboo, cocktail sticks are just not good enough!

The most important point is to remove ALL of the polishing media when the cleaning process is complete

1. Clean with metal polish.

2. Wash with a suitable solvent using cotton or tissue on a stick to clean in difficult areas,

3. Wash away the solvent.

4. Immerse in alcohol and then dry quickly using a hair drier

5. Check with at least a 10X hand lens and remove any remaining stains or dust with a fluff free tissue,

Each cleaned component should be stored in aluminium foil until ready for use. Prior to fitting each component should be checked once again with a hand lens, to ensure there are no debris remaining.

The Gun Chamber

1. In the case of the gun chamber, if it is looking clean simply rub it over for a few minutes "in situ" with a clean chamois leather, deer skin or similar material.

2. If the chamber looks slightly tarnished, with light blue or yellow deposits, clean it with 10% dilute ammonium hydroxide (40%) before the chamois clean.

3. If the chamber is very dirty remove it from the microscope, "CARE", and clean it with metal polish. Follow the metal polish clean with ammonia and then the chamois leather procedures.
