Leather Dressing

Leather dressings were at one time thought to be useful in extending the life of leather bindings. Experience has shown, however, that its benefit is primarily cosmetic and that the use of leather dressing by someone without professional expertise, does more harm than good.

Studies have shown that leather dressings can cause the leather to dry out over time.

Dressed leather may become stiff, and will be accompanied by darkening of the surface or staining.

If too much dressing is applied, or if it is applied too frequently, the surface of the leather may become sticky and attract dust.

Leather dressings can migrate through dry leather and stain the text pages of a book.

If a leather book has become stiffened through the use of leather dressing, proper handling techniques and support of the book structure will help to ameliorate the problem.

Polyester (Dupont Mylar Type D® or ICI Mellinex 516® ) dust jackets help prevent dry rotted leather from offsetting on to adjacent books and protect the covers from further deterioration as well.
