The authors describe this as the least invasive of the cleaning treatments. Wet-cleaning and solvent cleaning, like most interventive treatments, are irreversible processes. Not all textiles can be wet-cleaned and a list is provided of unsuitable textiles and materials found in composite artefacts. The treatment procedure is outlined in detail, together with advice on equipment. Solvent cleaning is used for the removal of oil-based stains that cannot be treated through washing, but little information is given as this form of cleaning is best left to professionals.
Preventive conservation is described as the key to protecting textiles during storage and display.
The use of inert materials is paramount to safeguarding their condition and correct storage using acid-free tissue and boxes, helps protect textiles from further damage. Selection of the most appropriate system, be it flat storage, rolling or hanging, is based on the size, condition and construction of the textile in question. For example, costume should only be hung if it is strong and not weighted by heavy beadwork, is strapless or bias-cut. It is important that the total weight is not taken on the shoulders but is distributed through the length of the garment. A hanging bag constructed from unbleached cotton calico protects historic costume from dust and light, while hanging with adequate room between items allows air to circulate.
