Abstract

Textile painting has characteristics that distinguish it from painting on canvas, and these differences also require a distinct conservation methodology. In this article, we discuss the removal of rust stains from a cotton textile painting created using rust printing and watercolor. The rust used in the artwork migrated across the fabric, generating stains that combined with adhesive and mold residues, altering the appearance of the work and making it more difficult to interpret. The rust stains were removed using chelating agents − citrate and oxalate − at controlled pH levels, applied in a xanthan gum gel to limit solvent migration within the fabric. Both chelating agents proved effective in cleaning and enabled a controlled treatment that meets conservation criteria for textile paintings.
