Abstract
An edge surface (18) of an article (16) is treated in a fluid (52) with a minimum effect on other adjacent side surfaces of the article by contacting the edge surface to the surface of the fluid such that the fluid wets the side surfaces and forms a meniscus adjacent to each of the side surfaces. In the meniscus the fluid stagnates and quickly becomes an inactive barrier which shields the side surfaces of the article, while the edge surface of the article remains exposed for the duration of the treatment to the active bulk of the fluid.
