Grumbacher Oil Painting Restorer is a surface cleaner for completed and dried oil paintings. It revives, refreshes and conditions a painting by removing surface soil. Apply to a lint-free cloth to gently clean the surface of a work while constantly turning the cloth so as not to rub soil into the painting. Use with care around highly textured surfaces. Oil painting restorer may be removed with a clean cloth dampened with turpentine. Made in USA.
