What constitutes ROUTINE MAINTENANCE of art objects?
If common-sense environmental factors are under control then most art works will fare very well. A good rule for any periodic maintenance is to minimize it as much as possible. This minimizes the risk to the work of art. Dusting is really the only operation an unskilled person should do. Although feather dusters are common, they should never be used because they are too abrasive. A soft Japanese paste brush or other soft, high-quality brush is all that is necessary for most objects. This operation should not be required more than twice a year or there is something seriously amiss with environmental controls in general. It is very dangerous to use old recipes or suggestions for surface cleaning paintings. Although these are found in many historic books they are very dangerous in the hands of the uninitiated. It is best to consult a qualified conservator.
