Oilskins (fabrics or skins treated with linseed oil to waterproof the material) were used for clothing and other protection. Oilskins received for conservation are usually very dirty, brittle, often split along the folds, and too stiff to open. Metal fastenings are corroded due to contact with salt water, and associated rubber and leather are deteriorated. Garments are generally worn and patched. Successful conservation treatments using polyethylene glycol waxes are described. Photographs, references. -- ICCROM
