How to brush vacuum an object

Removing dust and dirt by brush vacuuming (surface cleaning) can be very beneficial for many material types. However, removing dust and
residues from objects should be carefully considered as they may provide clues about where and how an object was made, even who used it.
Before you surface clean an object, ask yourself if the dirt is actually an important part of the item’s history. Do not brush vacuum if the surface of an object will be damaged, eg flaking paint.
