Preservation of Bank Notes |
|
|
Hands must be washed thoroughly and gloves must be worn to prevent stains caused by sweat, grease and dirt. Bank notes must be kept in controlled environment having 45-50% humidity at 25 degrees Celsius temperature. The room or cabinet must be dust-free. Insecticides can be used to keep away insects.
The paper used to reinforce the bank notes must be acid-free. In case of paper documents or materials getting wet, preservation must be performed instantly. Leaving such paper documents or materials to air-dry will result in the paper becoming attached and inseparable.
Keeping :
All paper materials must be kept in acid-free paper boxes or plastic bags (polyester, polyethylene or polypropylene) and the humidity must be monitored. | |

Preservation of Gold Items |
|
|
Dust and dirt cleaning: Only soft brushes and douche balls are allowed. Use a cotton swab with fine cotton and dip in a mixture of distilled water and non-ionic detergent to scrub the surface of the item and cleanse several times using cotton swabs and distilled water. Grease stains can be removed using ethyl alcohol or acetone.
Keeping :
Containers should be upholstered or cushioned with soft material. Items can also be wrapped with acid-free tissue. |

Preservation of Silver Items |
|
|
Cleaning silver items can be done the same way as for gold items. An alternative is to prepare a mixture made by grinding soft prepared chalk to powder and mix with 95% alcohol to create a taste with a consistency similar to toothpaste. Then use a cotton swab to dip into the mixture and scrub the surface of the item and cleanse several times with cotton swabs soaked with distilled water.
Keeping :
Each item should be wrapped seperately with soft acid-free tissue then wrapped over with anti-tarnish paper or wrapped with soft acid-free tissue and kept in plastic bags to prevent forming of dark stains caused by sulfuric pollutants in the air.
