The dehazer’s job is to remove ghost images, stains and telltale outlines of former print jobs formed by tiny fragments of ink embedded in the weave of the mesh. The mesh openings may be clear but these faint outlines remain. Depending on the fineness of the mesh and the kind of detail required in your next print job, ghost images can be ignored until they build up to a point where they begin to interfere with the process of exposing a new stencil. That's when you need to haul out the heavy artillery, your dehazer. This is the one you want to be careful of. Many of the popular dehazers on the market are caustic-based potassium hydroxide or sodium hydroxide (lye and soda ash). This is usually a caustic material, which is, fortunately, not required every time you reclaim a screen.
