Surface cleaning of parchment is typically completed using white vinyl erasers (solid and grated) and confined to areas where no media is present. Water baths, which sometimes use neutral detergents or alcohol as additives, can be used to clean as well as prepare the parchment for stretching as part of the conservation process. [ 19 ]

A spring pin (also called tension pin or roll pin) is a mechanical fastener that secures the position of two or more parts of a machine relative to each other. Spring pins have a body diameter which is larger than the diameter of the hole they are intended for, and a chamfer on either one or both ends to facilitate starting the pin into the hole.
γ is the liquid–vapor interfacial tension; γ SL is the solid–liquid interfacial tension; γ SV is the solid–vapor interfacial tension; S is the area of liquid–vapor interface; P is the excess pressure inside liquid; R is the radius of droplet base; Based on this equation, the excess free energy is minimized when γ decreases, γ SL ...
Feather dusters serve the same function as soft brooms or brushes, except that they are only meant to remove loose superficial dust from delicate surfaces (such as paintings and papercrafts) or around fragile items (such as porcelain and glassware). They are effective in cleaning tight areas, or areas where there are many odds and ends.
